All -

I'm a novice at R and I'm having difficulty combining text and an 
expression in the same label.

  I just trying to get Yield (kg ha-1) and have the -1 as superscript. What
  I came up with doesn't work. I'm stuck at trying to concatenate it with 
any other regular text.

  yield1 = "Yield (kg ha"
  yield2 = expression(^-1)
  yield3 = ")"
  ylabel = paste(yield1, yield2, yield3)

  boxplot(yield.kgha.st~env,data=lsmeans1,
  boxwex=0.3,
  main='Chinese Hybrids',
  ylim=c(0,5300),
  sub='',
  ylab=ylabel,
  xlab='')


any help appreciated,

  Josh
