Dear Ross,
I apologize, there was careless cut and paste, I am sorry. And my message took
long to appear on the list because I accidentally used an email address other
than the one I subscribed with, so that it had to be cleared manually before it
appeared. Thanks to the moderator for allowing it, by the way, and to you for
pointing the error.
I was a bit behind at the time (R 2.13.1, but 2.13.2 was out). I am way behind
now, as I did not have time to upgrade to 2.14. I cannot be certain this is
still an issue, but I would like to at least post a correct example.
pdf(file="/Users/dchabot/Documents/Programmes R/test.pdf") # works
plot(1:10)
dev.off()
pdf(file="~/Documents/Programmes R/test.pdf") # works
plot(1:10)
dev.off()
quartz(file="~/Documents/Programmes R/test.pdf", type="pdf") # does not work
plot(1:10)
dev.off()
quartz(file="/Users/dchabot/Documents/Programmes R/test.pdf", type="pdf") #
works
plot(1:10)
dev.off()
Only the 3rd example does not work:
> quartz(file="~/Documents/Programmes R/test.pdf", type="pdf") # does not work
Erreur dans quartz(file = "~/Documents/Programmes R/test.pdf", type = "pdf") :
Impossible de créer le périphérique cible Quartz, le type fourni n'est
peut-être pas supporté.
> plot(1:10)
> dev.off()

In his reply to my post, Prof. Ripley said that tilde expansion had to be
implemented into each graphics device. I did not know that, I thought it was
built-in R because of its Unix roots. So I guess we now have the answer. It is
not a big deal having to write the complete path, it just took me by surprise.
I would like to offer to add tilde expansion to quartz(), but I am not
qualified to do so.
