This function will add extra columns to an existing dataframe. The second argument 'clmn' should specify which column(s) of the dataframe the percentage should be calculated by dividing each column's row-element by it's sum. If x is not a dataframe, it will attempt to do a simple percentage operation on whatever input was passed to x.

manip

This R-extension package contains dozens of functions useful
for: database style joins [nerge()] & aggregation [bestBy(), groupBy() & regroup()],
database migration [dbWriteTable2()], file I/O [write.delim(), read.tab()],
text parsing / data mining [m()], data structure conversion [nv(), tab2df()],
summarizing & reporting [pct(), fit.1ln.rprt()], character string manipulation [m() & pad()],
legend table making [sstable() & leghead()] & plot placement [legend.position()],
plot annotation [labsegs() & mvlabs()], data visualization [pies(), spie(), & heatmatrix()],
and data exploration [hyperplot(), plot.xy.ab.p()], batch scripting [parseArgString()].
The package's greatest contributions stem from its database style merge,
aggregation and interface functions as well as in it's extensive
use and propagation of row, column and vector names in most functions.
The latest additions are plotting functions [confound.grid() & sparge()] that intake
a dataframe & formulas to visually resolve variable confounding (Simpson, 1951).
