Hi, I think I'm missing something obvious here but I can't seem to be able to scale tick marks and labels individually in persp. For example: x <- matrix(rnorm(100), 10) par(mfrow=c(2, 2)) persp(x, phi=35, theta=35, ticktype="detailed") persp(x, phi=35, theta=35, ticktype="detailed", cex=2) persp(x, phi=35, theta=35, ticktype="detailed", cex.lab=2) persp(x, phi=35, theta=35, ticktype="detailed", cex.axis=2) What am I doing wrong (or is persp only accounting for cex)? Setting the plotting options with par before each call produces the same result as above Cheers, Claus -- ***************************************** Claus Thorn Ekstr?m <ekstrom at dina.kvl.dk> Dept of Mathematics and Physics, KVL Thorvaldsensvej 40 DK-1871 Frederiksberg C Denmark Phone:[+45] 3528 2341 Fax: [+45] 3528 2350
