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)
  • 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 it’s 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.

gvsu215 0.3.1

Updates

  • plot_bar() will now show colors correctly when type = "count" is specified.
  • tbl_num_sum() will no longer show NAs when no NAs are present and na_rm = FALSE is given.
  • The second variable entered in infer_anova() is now coerced into a factor so that degrees of freedom are correctly calculated.

New Functions

You now may use infer_2mean() and infer_2prop() to perform a two-sample proportion or mean test, respectively. The main perk to this is the conf_int argument. When specified to TRUE, a confidence interval will be given in addition to the hypothesis test output.

These functions are provided as an alternative to infer_2prop_int(), infer_2prop_test(), infer_2mean_int(), and infer_2mean_test(). Rather than having two functions for intervals and tests, you can now do it in one function if you so choose.

gvsu215 0.3.0

Major Changes

Other Changes

  • The package vignette (README) has been changed to import images of all tables. The HTML output of the code does not work well with GitHub and the tables don’t appear there.

gvsu215 0.2.0

Major Changes

  • Two functions have been renamed. one_way() is now tbl_one() and two_way() is now tbl_two(). The old functions are not available.
  • plot_scatter(): The default value for legend_title is now NULL (which is then supplied with the variable name). You can still supply a new string for the legend title.

Other Changes

  • two_way() (tbl_two()) output cleaned up
  • plot_box() and plot_hist() will now not do scientific notation between certain ranges of numbers
  • corr() now shows the observations used (since this is not always just a sum of n1 and n2 missing)
  • added confidence interval to infer_paired()
  • The two-sample family of functions now show the correct levels of the grouping variable and the respective calculations about them.

gvsu215 0.1.1

  • general fixes to output layout and theme, especially to two_way()
  • rounding corrections
  • plot_scatter() now allows for a least squares line to be drawn in
  • bug fix in num_sum()

gvsu215 0.1.0

  • All package functions are now usable
  • All functions are documented
  • All functions have tests
