"file" is one of 113 CURLOptions ============== library(RCurl) "file" %in% listCurlOptions() ============== The following system command does work. curl http://bioconductor.org/packages/2.3/bioc/bin/windows/contrib/2.8/ABar ray_1.10. 0.zip -O I wonder how CurlOptions such as "file" or/and "write" could be set in RCurl package to fulfill the above curl functionality. Any suggestions? --- LiGang
