Changelog

gvsu215 0.6.6

• Correct table generation for expected chi-squared used with missing values.

gvsu215 0.6.5

• tbl_1var() and tbl_2var() will now only remove NAs for the variable(s) specified in the function call, not all NAs in the dataset

gvsu215 0.6.4

• correct error in proportion inference functions with the alternative argument not working properly
• add in examples of using the alternative argument

gvsu215 0.6.3

• Small axis adjustment to plot_bar() when using type = "percent"
• Proportion and mean hypothesis test functions now have a new argument alternative to specify which direction the test is. Options are "notequal" (the default), "greater", or "less"

gvsu215 0.6.2

• Corrected error in plot_bar() when a stacked bar chart was requested. Bar section heights will now match the actual proportion of the respective values.
• Two-sample tests and intervals now have merged, centered, grey cells to differentiate them from the group statistics.
• Flip-flopped the variable names in the titles of stacked bar charts to read *fill variable* by *x-axis variable*.

gvsu215 0.6.1

• Adjusted captions in infer_mean_* and infer_prop_*. Some intervals were not showing confidence levels and some tests were. These should be back in their regular places.
• infer_2mean_test() now has a mu0 argument to be used with the difference between the means is not equal to 0.

gvsu215 0.6.0

• plot_bar() now includes the ability to specify a stacked bar chart. fill must be a variable, then use the layout argument set to stack. (sbs, side-by-side, is the default).
• Various small fixes to documentation and vignettes

gvsu215 0.5.5

• All functions that have an na_rm argument now default to TRUE (rather than FALSE)
• KNOWN ISSUE: Table captions in pdf output have wonky spacing. This is believed to be a bug within flextable and is in progress.

gvsu215 0.5.4

• Updated spacing in tables for Word output
  • Line breaks in table headers are now forced with \n, users will need to specify their own line breaks in variable names
  • Max width of tables for non-interactive and non-HTML output (e.g., PDF and Word) is 6.9 inches. No max width is given for other outputs.
  • Note added to extending default behavior article.
• The spacing between clusters of the grouped bar chart (plot_bar() used with the fill argument set to a variable) has been increased. This was done by decreasing the width of the actual bars so having more categories in the x-axis variable might cause this spacing to decrease.

gvsu215 0.5.3

• Revert / clarify that all p-values for tests on the mean and the proportion are two-tailed

gvsu215 0.5.2

• Various calculation corrections. Mostly in functions dealing with proportion inference regarding standard error and confidence intervals.
• P-values now show as one-tailed

gvsu215 0.5.1

• One-sample inference functions have a new argument. These can be used to specify the null hypothesis value you are testing against. The null argument no longer works.
  • mu0 for means
  • p0 for proportions

gvsu215 0.5.0

• The axes for tbl_2var() were flipped so I flipped them back the right way (which is the way it was before).
• All inference functions that deal with means have a new argument: null which, by default, is set to zero. Use this argument
• Corrections to cheatsheet and extending behavior articles.

gvsu215 0.4.7

• You can now see proportions in tbl_1var() in addition to percents. Use with_prop = "yes".
• Ever wanted to make missing values disappear in one-way and two-way tables? Now you can! tbl_1var() and tbl_2var() support the na_rm argument.
• The axes for tbl_2var() were flipped so I flipped them back the right way.
• NEW FUNCTIONS / RENAMED FUNCTIONS which allow for hypothesis tests for one sample proportion and one sample mean (previously we only had support for confidence intervals)
  • infer_1prop() is now infer_1prop_int()
  • infer_1mean() is now infer_1mean_int()
  • NEW: infer_1prop_test()
  • NEW: infer_1mean_test()
• plot_box() now has a breaks argument (which works just like that of plot_hist()). The plot should also be a little smarter by adding some extra padding around the min and the max of the plot.

gvsu215 0.4.6

• A new argument was given to plot_bar(): orient, which can take on either “vertical” or “horizontal” and can be used to flip the axes of the plot.
• plot_bar() and plot_box() have a new argument: dodge which will take on an integer greater than 0 (default 1) to dodge x-axis labels should they overlap.
• plot_hist() will now work again with groups. Oops!

gvsu215 0.4.5

• The student cheatsheet was updated. Functions that don’t have an na_rm argument no longer show that as an option.
• The Instructor’s Guide was renamed to accurately describe its content.
• Histograms now default to showing non-overlapping x-axis values, if necessary.
• infer_chisq now removes all NAs automatically. Output now shows how many observations there were originally as well as how many were used for the output.

gvsu215 0.4.4

• tbl_num_sum() output: If missing values are removed (i.e., na_rm = TRUE) the number missing values are still shown in the table. Previously this column was removed but it still is good information to show.

gvsu215 0.4.3

• Appearance changes for some tables (such as font size and borders)
• Correct error from previous release where the function dplyr::na_if() was used without the :: syntax.

gvsu215 0.4.2

• You now can use base::read.csv() with the functions! A unique case presented itself where a missing value was recorded as “” (the empty string) and was not detected by default from `read.csv(). All functions now search character variables for empty strings and replace them with true NAs. This could be expanded in the future.

gvsu215 0.4.1

• All tables should be properly right-aligned
• Cosmetic changes in multiple plots and tables
• Add padding zeroes in the case where the rounded number is shorter than the number of digits supplied
• Clarification updates to captions/titles in plot_bar and tbl_pctile

gvsu215 0.4.0

• All arguments the previously took either TRUE or FALSE as a value have been converted into vector-style arguments. For example in plot_scatter(), the ls_line argument now accepts either “show” or “hide”. The only exception to this is na_rm, wherever it appears.
• Error and warning messages were updated. They are now slightly more user-friendly thanks to the cli and rlang packages.
• More comments were added to the source code to help me remember what I was doing six months from now.

gvsu215 0.3.8

• Corrected error in infer_paired() which had an incorrect use of the :: syntax
• Updated figures displayed in README (to now accurately show the right alignment of table body cells)

gvsu215 0.3.7

• Values in tables are now rounded with the standard “nearest digit” format for all numbers not between -1 and 1. Numbers between -1 and 1 are rounded using significant digits (i.e., non-zero digits after decimal) but use the same digits argument as the standard rounding.
• All p-value rounding has been adjusted. Any p-value less than 0.0001 will now display “< 0.0001”. Other values will display the true value and follow the rounding rules mentioned above.

gvsu215 0.3.6

• plot_hist(): the binwidth argument has been deprecated and is no longer available. Instead, use breaks which, when used, helps to line up the bins and x-axis ticks for better readability and interpretation.
• The student cheatsheet was slightly reworked to line up with textbook chapters.

gvsu215 0.3.5

• tbl_num_sum() now shows number of NAs in caption when na_rm is TRUE and does not show the “missing” column (which was all 0s in this case). This funciont will also now correctly display “NAs Removed” in the caption.
• Default table output width is now 6 inches to avoid bleeding into margins of PDF and Word documents.

gvsu215 0.3.4

• Package now depends on ggformula (rather than imports) to help avoid a potential namespace issue when users have not loaded ggformula.
• Small adjustments to plot themes
• The output from infer_chisq(., type = "expected") now shows both variable names on the table.

gvsu215 0.3.3

• Mostly internal changes
  • Small documentation updates
  • Reworked in-function variable names
  • Updated internal tests
  • Redesigned student cheatsheet, built instructor’s guide

gvsu215 0.3.2

• Updated documentation (including how to add a least squares line to plot_scatter()).
• Tried to change a legend title on a grouped scatterplot and it didn’t work? Now it does!
• A new vignette has appeared! It contains a code shell/template for each of the functions in the package. For out-of-the-box use, simply copy the code and fill in the blanks.
• Some error messages will show up less frequently.
