ftp connections for uploading files
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 2009/1/8 Duncan Temple Lang <duncan at wald.ucdavis.edu>:

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. On Thu, 8 Jan 2009, Thomas Loridan wrote:
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 -- Thomas Loridan King's College email: thomas.loridan at kcl.ac.uk webpage:http://geography.kcl.ac.uk/micromet/tloridan/index.htm
