Description Frequency functions Sample size functions Other helper functions Stata replica functions SAS replica functions

The helpR package contains descriptive functions for tasks such as making print-friendly bivariate tables, sample size flow counts, and more. It also contains R approximations of some common, useful SAS/Stata functions.

The helper functions `bivariate_compare`

and
`univar_freq`

create frequency tables. `univar_freq`

produces simple n and percent for categories of a single variable,
while `bivariate_compare`

compares continuous or categorical
variables across categories of a comparison variable. This is particularly
useful for generating a Table 1 or 2 for a publication manuscript.

`sample_flow`

produces tables illustrating how final sample
size is determined and the number of participants excluded by each
exclusion criteria.

`nagelkerke`

calculates the Nagelkerke pseudo r-squared for a
logistic regression model.

`ladder`

, `gladder`

, and `pwcorr`

are
approximate replicas of the respective Stata functions. Not all
functionality is currently incorporated. `stata_tidy`

reformats R model output to a format similar to Stata.

`proc_means`

is an approximate replica of the respective SAS
function. Not all functionality is currently incorporated.
