[STATSGRASS] graphics in R

[Matteo Dall'Amico]

Thank you Jaroslaw,
I tried but "plot" doesn't seem to accept "add" as an argument:

 > plot(temp[,2],add=TRUE)
Warning messages:
1: "add" is not a graphical parameter in: plot.window(xlim, ylim,  
log, asp, ...)
2: "add" is not a graphical parameter in: plot.xy(xy, type, pch, lty,  
col, bg, cex, lwd, ...)
3: "add" is not a graphical parameter in: axis(side, at,  
as.graphicsAnnot(labels), tick, line, pos, outer,
4: "add" is not a graphical parameter in: axis(side, at,  
as.graphicsAnnot(labels), tick, line, pos, outer,
5: "add" is not a graphical parameter in: box(which = which, lty =  
lty, ...)
6: "add" is not a graphical parameter in: title(main, sub, xlab,  
ylab, line, outer, ...)

Suggestions?
Thanks,

Matteo
