Hello!
I have two question that rose from trying to tacle the same problem in two
differnet ways.
What I want to do is to plot axes (only values or labels, no tick marks) in
such a way that 'cex' can be very small, text can be perpendicular to
the
axis (as in axis(las=2) ) and the text is stil at the right position.
Let me demonstrate with a small example:
plot(0:100/100,0:100/100,axes=FALSE)
axis(side=3,at=0:100/100,labels=0:100,las=2,cex.axis=0.1)
The text on the axis should be at the same points as tick marks, but it is
shifted right.
I tried to bypas the problem by using function 'text', which puts the
text
at the correct positions, however, it has another problem. I would like to
rotate the text, but if I use 'str=90' (to rotate the text for 90
degrees),
I get a warning massage:
Warning message:
parameter "str" couldn't be set in high-level plot() function
This suprises me, since if I read the help correctly ('?par'), then this
should not happen.
So if anyone can either hepl me to rotate the text in 'text' or to
correctly
plot the text in 'axis', I would be very grateful.

It may be a visual screen artifact of the small font size you are using. If you increase the cex.axis to 0.25 (for example), it becomes clear that the labels are in the proper position. I put up a PDF containing the plot at: www.MedAnalytics.com/Rplots.pdf I used the following code: pdf() plot(0:100/100, 0:100/100, axes = FALSE) axis(side = 3, at = 0:100/100, labels = 0:100, las = 2, cex.axis = 0.1) axis(side = 1, at = 0:100/100, labels = 0:100, las = 2, cex.axis = 0.25) dev.off() I'll leave that up for a bit for review. I presume that you have the Acrobat Reader under Windows? Relative to the use of text() for rotating axis labels, see: http://cran.r-project.org/doc/FAQ/R-FAQ.html#How-can-I-create-rotated-axis-labels_003f HTH, Marc Schwartz
Have you tried the adj parameter in par as in
axis(side=3,at=0:100/100,labels=0:100,las=2,cex.axis=0.1, adj = 0.5)
?

Hi Ales,
Think you might have made a typo, the parameter in par is "srt" not
"str",
hope that helps.
