Hi,
I used the command ggplot as follows...
p<-ggplot(a,aes(x=a$V1,colour=a$V2,fill=a$V2))
p + geom_density(alpha = 0.2,xlim=c(-10,10),ylim=c(0,0.5))
when I say,
dev.print(device=postscript,file="/alpha/dct.pdf")
I get
Warning message:
In grid.Call.graphics("L_polygon", x$x, x$y,
list(as.integer(1L:length(x$x)))) :
semi-transparency is not supported on this device: reported only once per
page
the pdf has error
any help?
