Description Usage Arguments Value Author(s)
Can specify a different col, lty and/or lwd for each line
(defaults are all 1). unique.lines
will work out a
unique combination of col and lty for each row of x (num
rows <= 64)

x 
a matrixlike object of data, with each row to be plotted in a single line (if type draws lines) 
auto.log 
if the data is in the range [0,1] then it can be converted to log10. Useful if x contains pvalues. 
symmetrical 
If the data in x is centred approx
about 0, then setting to 
unique.lines 
works out a unique combination of line colour and type (col and lty) such that the lines plotted are as unique as possible (ie 8 coloured solid lines, then 8 dotted etc) 
lty.cor 
If x contains records that are correlated, and perhaps anti correlated, setting to TRUE will work out which lines are anti correlated, and plot them as dashed lines, with all of the correlated lines drawn as solid lines. 
legend.pos 
see

none – used to plot.
