R Plot function
Summary of R plot symbols, as specified by pch
Plot symbols (plot character: pch) in R are specified by integers 1 to 25. I can't remember them, but it's easy to draw them to see what they are.
Draw R plot characters
# draw a plot, use all 25 plot characters # specify cex=2 so they are easier to see (cex = character expansion factor) plot(1:25, cex=2, pch=c(1:25), xlab="pch", main="pch Summary (plot char)")
R is available from CRAN
