Latex symbols in R (\perp and \parallel)

I am sure this is a one-liner, but I cannot find the R command to generate the LaTex symbols \perp and \parallel.
I took Dieter Menne's and Brian Ripley's examples, extended them slightly with Hershey font analogues, and posted the results at http://wiki.r-project.org/rwiki/doku.php?id=tips:graphics-misc:symbols I couldn't find the "parallel" symbol in font 5 anywhere. I tried to create a table of the contents of font 5 (R code below), but none of the permutations I tried worked ... z <- expand.grid(0:16,0:15) ch <- sapply(z[,1]+16*z[,2],function(x) format(as.hexmode(x),zero.print=TRUE)) d <- data.frame(z,ch) d <- d[c(-1,-272),] plot(d[,1],d[,2],type="n") text(d[,1],d[,2],paste("\x",d[,3],sep=""),font=5)
