Hello,

You have an extra "argument" to getURL that is _not_ an argument: 
ftp://ftp.use.epsv/
To get the list of files just do

url <- "ftp://ftp.cpc.ncep.noaa.gov/fews/AFR_CLIM/ARC2/DATA/1985/"
filenames <- getURL(url, dirlistonly = TRUE)
fn <- unlist(strsplit(filenames, "\r\n"))

# To download the files
destdir <- "C:/Rui/Temp/"  # Adapt to your system
lapply(fn, function(x) download.file(paste0(url, x), paste0(destdir, x)))


Hope this helps,

Rui Barradas
