I am having difficulties creating lower case Greek letters.
For example
plot(0,0, type = "n")
text(-0.5,1, expression(beta) )
text( 0.5,1, expression(alpha) )
produce the upper case letters B and A.
Running
demo("plotmath")
In the Symbolic Names
Alpha - Omega ! 7
alpha - omega Capital greek letters
so I suspect it may have something to do with my system, but
I am at a loss as to what. Any suggestions as to what to check
would be appreciated.
I am running R version 2.1.0 on Debian Linux - version sarge.
Well, see the posting guide and follow its advice -- 2.2.1 beta is available so you are 3-epsilon versions out of date. Beyond that, you have not told us your graphics device. I suspect this is the X11() device and so an X11 font issue. Try
options("X11fonts")
$X11fonts [1] "-adobe-helvetica-%s-%s-*-*-%d-*-*-*-*-*-*-*" [2] "-adobe-symbol-medium-r-*-*-%d-*-*-*-*-*-*-*" and see if xlsfonts gives you anything sensible for the second pattern, replacing %d by *.
