Try system() with curl or a decent ftp client (I don't see that package
RCurl covers this, but it might despite its description only mentioning
HTTP).
It does support FTP, and all of the protocols that are supported in
the installed libcurl, so it depends the configuration options for
libcurl itself.
The protocols it handles can be found via the curlVersion() function, e.g.

curl offers a busload of useful tricks like proxy support, user authen-
tication, ftp upload, HTTP post, SSL connections, cookies, file trans-
fer resume and more. As you will see below, the amount of features will
make your head spin!
Ftp protocols (and there are more than one) are fiendishly complicated,
especially if proxies are involved.
BTW, this is yet another case where knowing your OS would have helped
give a more precise answer. See the posting guide.

Hi all,
I would like to upload some plots I create wth R via ftp or something
similar but I don t really understand which command/syntax I should
use:
should I go for make.socket + write.socket or try and create
environment variables like frp_proxy_user and then ftp my files? how?
many thanks for your help
Thomas
