Dear all, For local machine, "list.files" works well to list all files recursively in particular directory. But , is there a function can be used to list all files in particular directory on a FTP site? I use functions of RCurl package to do something like: =========================================================== library(RCurl) getURL("ftp://ftp.ncbi.nih.gov/pub/geo/DATA/SOFT/GDS/")->inter ###inter give some meaningful results getURL("ftp://ftp.ncbi.nih.gov/pub/geo/DATA/supplementary/samples")->i nter2 ###above command did not work Error in curlPerform(curl = curl, .opts = opts, .encoding = .encoding) : RETR response: 550 =========================================================== Any suggestions? Many thanks! --- Ligang [[alternative HTML version deleted]]
