⚠️There's a newer version (3.0.1) of this package.Take me there.

gdata (version 2.19.0)

Various R Programming Tools for Data Manipulation

Description

Various R programming tools for data manipulation, including medical unit conversions, combining objects, character vector operations, factor manipulation, obtaining information about R objects, manipulating MS-Excel formatted files, generating fixed-width format files, extracting components of date & time objects, operations on columns of data frames, matrix operations, operations on vectors, operations on data frames, value of last evaluated expression, and a resample() wrapper for sample() that ensures consistent behavior for both scalar and vector arguments.
