evaluate

evaluate provides tools that allow you to recreate the parsing, evaluation and display of R code, with enough information that you can accurately recreate what happens at the command line. Evaluate + replay works very similarly to source(), but is written in such a way to make it easy to adapt for other output formats, such as html or latex.

library(evaluate)

There are three components to the evaluate package:

• parse_all(), a version of parse that keeps expressions with their original source code, maintaining formatting and comments.
• evaluate(), which evaluates each expression produced by parse_all(), tracking all output, messages, warnings, and errors as their occur, and interleaving them in the correct order with the original source and value of the expression.
• replay(), which outputs these pieces in a way that makes it look like you’ve entered the code at the command line. This function also serves as a template for other output formats.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
