package

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').
