Hi all,

I know that I can for instance draw to plots in one using

nf<-layout(matrix(c(1,2),1,2,byrow=FALSE))

Imagine I have 3 files:

plot1.jpeg
plot2.jpeg
plot3.jpeg

Anyone knows if I can read them and put on one colum and three rows reading
directly from the jpeg file?


Yes, there are many packages around,

One idea:

download.file("http://www.user2007.org/photos/r-cake.jpg";, jpfile <- 
tempfile(), mode="wb")
library("ReadImages")
jp <- read.jpeg(jpfile)
par(mfrow=c(3,1))
plot(jp)
plot(jp)
plot(jp)


Best,
Uwe Ligges




Many Thanks
