[R] [FORGED] Re: bar plot add space to group data

[Jim Lemon]

Hi Rolf,
That's what comes of being in a hurry.

legend(4.1,30,c("A+","A","B","C","D","E","U"),
 fill=c("white","lightblue","blue","orange","green","red","pink"))

and I thank you for alerting me to the fact that the legend arguments
in barp don't position the legend properly. I'll fix it.

Jim
