[R] barplot -issues with axis and labels not appearing

[Jim Lemon]

Hi Pierre,
I get a reasonable plot using the following code:

par(mar=c(6,4,4,2))
barpos<-barplot(unlist(GEP.data2),
 main="Global Portfolio Weights",
 col.main="gray", col=blues9,
 cex.axis=1, ylim=c(-1,1), las=2,
 cex.lab=1, cex=0.8)
axis(1,at=barpos,labels=rep("",8))

For one thing, you don't need the "beside=TRUE" argument as there is
only one vector of values to display. The small value for "cex.axis"
made the tick labels unreadable on my display. If you would like to
have the bar labels horizontal, have a look at the "staxlab" function
in the plotrix package.

Jim

Thanks Pierre
