Here's a question: I noticed that when I tried to create this simple
graph of rectangles and text, R appears to generate text that is
rasterized (this is seen both on the monitor and when the output is
directed to a pdf file). Any thoughts?
value.seq <- c("<4",as.character(seq(from=4,to=10)),">11")
frame()
par(usr=c(0,10,0,10) )
for (r in 1:9) {
rect(r,3,r+1,3.75, border = NA, col=heat.colors(9)[r])
#this text does not appear to be rasterized
text(r+0.5,2.75, value.seq[r], cex=0.5)
#this text appears to be rasterized
text(5.5,2.25,"expression (log2)", cex=0.5) }
Thanks,
Andrew
