Dear list,  

I am trying to place 3 density functions in one Figure, 1 row by 3 columns:


op <- par(mfrow = c(1, 3),pty='s')

pdf(file="Fig_den.pdf")

barplot2(tab.in,plot.grid=TRUE,xlab="number of HGT_in",ylab="density")

lines(dneg,col="red",lwd=2)

barplot2(tab.out,plot.grid=TRUE,xlab="number of HGT_out",ylab="density")

lines(dnegout,col="red",lwd=2)

barplot2(vt,plot.grid=TRUE,xlab="number of HT POGs",ylab="density")

lines(dnegpog,col="red",lwd=2)

dev.off()

par(op)


Somehow in file Fig_den.pdf these figures are on the separate pages.

However, I get exactly what I need in the console window.

Could someone please explain me what I am doing wrong when saving Figure in pdf?  

Thank you!

Galina
