Hi Pedro --
Here's my advice, maybe others will have better ideas.
Get readLines to work, and do not worry about AnnBuilder until that is
figured out.
To get readLines to work, I suggest making only changes that are
essential. So remove the environment variables you mention, and the
options you set in R. What does
> readLines("
ftp://ftp.ncbi.nih.gov/repository/UniGene/Homo_sapiens/Hs
.info")
produce? It sounds like it will fail to connect to the ftp server. So
then try
% export ftp_proxy=http://12.16.105.41:8080
% export ftp_proxy_user="anonymous"
% export ftp_proxy_password="plopez at cnic.es"
HOWEVER, make sure that these proxy settings are correct (this depends
on your specific site; we cannot help you here). In particular the
ftp_proxy should likely be ftp://...:21 ('21' is the default ftp port,
but could be different for you; 8080 is the standard http port and
unlikely to be correct for ftp; using an http:// for ftp proxy doesn't
sound right to me, either).
In R, set
> optionsinternet.info=0)
and try
> readLines("
ftp://ftp.ncbi.nih.gov/repository/UniGene/Homo_sapiens/Hs
.info")
again. Now what is the output? If it looks like you saw earlier, e.g.,
Error in file(con, "r") : unable to open connection In addition:
Warning
messages:
1: using FTP proxy ' http_proxy=http://12.16.105.41:8080' in:
file(con, "r")
2: RxmlNanoFTPGetMore : read 0 [0 - 0] in: file(con, "r")
3: failed to get response from server in: file(con, "r")
then likely it means that your ftp_proxy is incorrect.
Hope that helps; this is really a bit of a guess on my part.
Please also arrange to send your email as plain text, as the 'helpful'
formating (e.g., parsing URLs) makes the message difficult to read.
Hope that helps, and please let us know how it goes.
