Hey, Does anyone know of an equivalent to the LaTeX \perp (perpendicular) symbol for adding to R plots? Parallel is easy enough ("||"), but I haven't been able to find a way of adding perpendicular. The plotmath documentation doesn't mention how to do it, so I'm inclined to think that it doesn't exist - but surely there must be some way of achieving the desired result,

Hey Felix, So basically what you want is a figure containing a block of four plots, with a main title for the figure? If that's the case then something like this should work: # BEGIN CODE # par(oma=c(0,0,1,0), mfrow=c(2,2)) for(i in 1:4){ plot(NA,xlim=range(0,10),ylim=range(-5,5)) title(paste("Plot ",i,sep="")) } par(mfrow=c(1,1), oma=c(0,0,1,0)) mtext("Main

Hey, The syntax is: if(condition){ #COMMANDS_A } else{ #COMMANDS_B } Hope this helps, -Matt On Fri Apr 27 15:07 , elyakhlifi mustapha <elyakhlifi_mustapha at yahoo.fr> sent: >hi, >I don't understand my error when I submit this program > >> for(k in LR) { >+ donRep[[k]] >+ M[[193]] >+

Hi there, I've written a script for reading 3D simulation data into R, rendering it using RGL, and then saving the resulting plot using the snapshot3d() function. The results are fantastic! However, whenever RGL plots anything it automatically brings the viewing window into focus. Since I'm producing a large number of plots in a loop, my machine becomes almost unusable for the

Hey all, I'm trying to create a plot of two semi-transparent regions. The reason they need to be partially transparent is so that I can see if there's any overlap. Here's some example code: # BEGIN pdf(file="test.pdf",version="1.4") plot(0,0,type="l",ylim=range(-3,3),xlim=range(-1,5)) polygon(c(0,1,2,3,4,3,2,1,0), c(0,1,2,1,0,-1,-2,-1,0),
