[R] [EXT] Re: adding results to plot

[David K Stevens]

This is pretty kludgy but ...

res.p <-capture.output(x.t)
res.pl <- ''
res.nul <- sapply(res.p,function(x.c) res.pl <<- 
paste(res.pl,res.c,sep='\n'))
text(x,y,rel.pl,pos=4,cex=mycex)

This will replicate the print object for the t.test that goes to the 
screen so you can add it to a plot. One note, the output of several 
lines will be left justified at the x-location but centered vertically 
on the y-location. Experimental with the cex setting to fit it on your 
plot. It will also put two blank lines above and one below so you might 
strip those out for better positioning
