HI all,
I'm failing to understand why the following is happening.
In this plot I rely on two text functions both using parse.  The second one works properly by writing a gamma symbol 5 times, the first one only works properly four times.  The only difference is that I add a string to the paste function of that which does work properly.  Why does it behave like this?
thanks so much!

plot(1,1,type='n',ylim=c(-2,2))
for(gam in seq(-1,.25,length=5)){
 #doesn't repeat gamma symbol properly
  text(.8,gam,parse(text=paste("gamma",gam,sep='')),cex=.75,adj=0)
 
# however this works if an additional string is included in the paste function
  text(1,gam,parse(text=paste("gamma","~hi",gam,sep='')),cex=.75,adj=0)
}
