scaledic - A dictionary for scales

Have you ever thought it might be helpful to have additional information on a variable in a data frame giving you a longer description, the scale this item belongs to, whether it has a reverse coding, valid values, values labels? And wouldn't it be nice you could check for typos, impute missing values, build scale scores, switch between long and short labels in a graph etc. just with a few simple command within R?

This is what scaledic is aiming for. scaledic is an R package for extending data frames and tibbles with several scale related attributes. It is designed to implement (psychometric) scale information to items of a data frame. These include values, labels, sub scales, weights etc.. A couple of functions help to organize, extract, replace and impute missing values, find typos, build scale scores etc.

For now, scaledic is already working and up to the task but still in an experimental stage where I might change the basic syntax. Also documentation is poor. I am working on that.

Basically, scaledic loads a dictionary file that contains all relevant information and applies these to a data frame. Here, every variable corresponding to the ones describes in the dictionary gets a new attribute dic which contains a list with all dictionary values for that variable.

The package contains an example data frame ITRF with 4767 participants that filled out the "integrated teacher report form" questionnaire. dic_ITRF is a corresponding dictionary file for the ITRF (as the original data were collected in Germany the dictionary file has also the German item labels).
