Hello R-listers,[won't work anyway]
I am developing a function which needs to create jpeg files from some plots. To create the jpeg files I use the instruction dev.print(jpeg, file=c://graph.jpg",width=400,height=400).
Until now everything has been fine, but now I have a special plot which is formed by 3 separate plots joined with the instruction "layout":
Use dev.copy() instead (it redraws the figure, see ?dev.copy), or even better use the jpeg() device directly, if you are on Windows.
nf <- layout(matrix(c(2,0,1,3),2,2,byrow=TRUE), c(3,1), c(1,3), TRUE);
layout.show(nf);
The graphic in R is ok, but the problem comes when I try to change the size of the graphic in the function dev.print, as it seems to not expand the layout graphic to the size I have chosen (it creates an image with the right size, but expanding the margins and not the image itself, while with "normal" plots the image is expanded). Anyone could tell me how to change the size of the image?
Thank you in advance,
Juan
