plot.confound.grid

confound.grid

Plot a grid of x y plots showing how a third confounding variable 'z' changes the slope.

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).
