Hi Thomas
Rather than getting into the details of libcurl options
which are quite general and very flexible, I thought
it was easier to write an explicit ftpUpload() function
that takes care of the details.
You need a new version of the package (as it contains the function and
a small change to the C code), but I don't have the time to build the
Windows version for the next few days.
The function can be used as
ftpUpload("path/to/file", "ftp://server/path/to/target/file";,
userpwd = "login:password")
and you can deal with contents in memory too rather than from a file.
HTH,
D.

Thanks a lot Duncan
Sorry to insist with my questions but I am very lost with these Rcurl
commands...
could you point out the few ones I need to set up an ftp connection
and just upload a file ?
Greatly appreciated
Thomas

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.
curlVersion()

From 'man curl'
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
