Masked User Input

A micro-package for reading "passwords", i.e. reading user input with masking, so that the input is not displayed as it is typed. Currently we have support for 'RStudio', the command line (every OS), and any platform where 'tcltk' is present.

A micro-package for reading user input in R with masking, i.e., the input is not displayed as it is typed.

Currently, RStudio, the command line (any OS), and platforms where the tcltk package is available are supported. We believe this hits just about everything, but for unsupported platforms, non-masked reading (with a warning) is optionally available. See the package vignette for more information.
