R-helpers:

I'm trying to retrieve the contents of a directory from an ftp site
(ideally, the file/folder names as a character vector):
"ftp://e4ftl01.cr.usgs.gov/MOTA/MCD12C1.005/"
# (MODIS data)

Where I get the following error via RCurl:
require("RCurl")
url <- "ftp://e4ftl01.cr.usgs.gov/MOTA/MCD12C1.005/"
filenames = getURL(url,ftp.use.epsv=FALSE,ftplistonly=TRUE)
> Error in function (type, msg, asError = TRUE)  : RETR response: 550

Through some sleuthing, it turns out the ftp site does not support NLST
(which RCurl is using), but will use "ls" to list the directory contents --
is there any way to use "ls" remotely on this site?  Thanks!
