title: 'rfriend: Provides Batch Functions and Visualisation for Basic Statistical
  Procedures'
version: 3.1.0
doi: 10.32614/CRAN.package.rfriend
abstract: 'Designed to streamline data analysis and statistical testing, reducing
  the length of R scripts while generating well-formatted outputs in ''pdf'', ''Microsoft
  Word'', and ''Microsoft Excel'' formats. In essence, the package contains functions
  which are sophisticated wrappers around existing R functions that are called by
  using ''f_'' (user f_riendly) prefix followed by the normal function name. This
  third version of the ''rfriend'' package focuses primarily on data exploration,
  including tools for creating summary tables, f_summary(), summary figures, f_scan(),
  outlier detection and removal, f_outlier() and f_remove_outliers(), performing data
  transformations, f_boxcox() in part based on ''MASS/boxcox'' and ''rcompanion'',
  and f_bestNormalize() which wraps and extends functionality from the ''bestNormalize''
  package. Furthermore, ''rfriend'' can automatically (or on request) generate visualizations
  such as boxplots, f_boxplot(), QQ-plots, f_qqnorm(), histograms f_hist(), and density
  plots f_density(). Additionally, the package includes several statistical test functions:
  f_aov(), f_chisq_test(), f_corplot(), f_kruskal_test(), f_lmer(), f_glm(), f_t_test(),
  f_wilcox_test(), for sequential testing and visualisation of the similar named ''stats''
  functions. These functions, except for f_chisq_test(), support testing multiple
  response variables and predictors, while also handling assumption checks, data transformations,
  and post hoc tests. Post hoc results are automatically summarized in a table using
  the compact letter display (cld) format for easy interpretation. The package also
  provides a function to do model comparison, f_model_comparison(), and several utility
  functions to simplify common R tasks. For example, f_clear() clears the workspace
  and restarts R with a single command; f_setwd() sets the working directory to match
  the directory of the current script; f_theme() quickly changes ''RStudio'' themes;
  and f_factors() converts multiple columns of a data frame to factors, and much more.
