Various R Programming Tools for Data Manipulation

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, elem, env, humanReadable, is.what, ll, keep, ls.funs, Args,nPairs, nobs),
  • manipulating MS-Excel formatted files (read.xls, installXLSXsupport, sheetCount, xlsFormats),
  • generating fixed-width format files (write.fwf),
  • extricating 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).
