Hi, first of all, I would like to take this opportunity to thank all of you "answer guys" for giving such detailed answers. I think I've learned about as much from all these answers as from the different S/R documents I've read so far. Anyway, I ran into a incompatability between S and R, that is, R does not know the "ticks=T/F" argument to functions like axis and plot. Knowing that R is not S, I tried to do it in a different way by adding "tcl=0" to the axis call. This works fine, however, in next calls to axis, it seems to remember this tcl setting, whereas settings like tck are not remembered. Is there a rationale behind this behavior, or is this a bug? Below is the code which demonstrates this, ran in R version 63.1, on a linux machine: plot(c(1:10),c(1:10),axes=F,type="n"); box(); par()$tcl # [1] -0.5 axis(1,c(1:10),tcl=0) par()$tcl # [1] -0.5 # I expected the next command to draw tick marks, but they don't show axis(2,c(1:10)) # Draw them anyway axis(2,c(1:10),tcl=-0.5) # Show that other arguments are not "remembered" axis(3,c(1:10),tck=0.5) axis(4,c(1:10)) Greetings, Hedderik. -- http://www.swi.psy.uva.nl/usr/rijn -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
