I'd like to create diagrams for dynamic web-pages via a cgi-script that itself uses R. Sadly, I found out that the png and jpeg devices need an X-server :-( , so I cannot use these nice devices. Does any one have any experience using R for on-the-flycreation of graphics for web-pages...?
One possibility is to generate a pdf file, then redirect the user's browser to
that file. Here are a few relevant lines from such a cgi script:
## Inside the R code:
pdf("mynewgraph.pdf")
## Graphics commands
dev.off()
## After R has run:
print "<META HTTP-EQUIV=Refresh CONTENT='0; URL=mynewgraph.pdf'>";
