gdata

Various R programming tools for data manipulation, including:

• medical unit conversions (ConvertMedUnits, MedUnits),
• combining objects (bindData, cbindX, combine, interleave),
• character vector operations (centerText, startsWith, trim),
• factor manipulation (levels, reorder.factor, mapLevels),
• obtaining information about R objects (object_size, env, humanReadable, is.what, ll, keep, ls.funs, Args, nPairs, nobs),
• generating fixed-width format files (write.fwf),
• extracting components of date & time objects (getYear, getMonth, getDay, getHour, getMin, getSec),
• operations on columns of data frames (matchcols, rename.vars),
• matrix operations (unmatrix, upperTriangle, lowerTriangle),
• operations on vectors (case, unknownToNA, duplicated2, trimSum),
• operations on data frames (frameApply, wideByFactor),
• value of last evaluated expression (ans), and
• wrapper for sample that ensures consistent behavior for both scalar and vector arguments (resample).
