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.
