sjmisc - Data and Variable Transformation Functions <img src="man/figures/logo.png" align="right" />

Data preparation is a common task in research, which usually takes the most amount of time in the analytical process. Packages for data preparation have been released recently as part of the tidyverse, focussing on the transformation of data sets. Packages with special focus on transformation of variables, which fit into the workflow and design-philosophy of the tidyverse, are missing.

sjmisc tries to fill this gap. Basically, this package complements the dplyr package in that sjmisc takes over data transformation tasks on variables, like recoding, dichotomizing or grouping variables, setting and replacing missing values, etc. A distinctive feature of sjmisc is the support for labelled data, which is especially useful for users who often work with data sets from other statistical software packages like SPSS or Stata.

The functions of sjmisc are designed to work together seamlessly with other packages from the tidyverse, like dplyr. For instance, you can use the functions from sjmisc both within a pipe-workflow to manipulate data frames, or to create new variables with mutate(). See vignette("design_philosophy", "sjmisc") for more details.
