| PackageDescription | 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'). |
