Dear list, How to use functions in RCurl to download a zipped file such as the one listed in the following URL: http://bioconductor.org/packages/2.3/bioc/bin/windows/contrib/2.8/ABar ray_1.10.0.zip Following code does not work: getURL(" http://bioconductor.org/packages/2.3/bioc/bin/windows/contrib/2.8/ABar ray_1.10.0.zip ") nor : getURL(" http://bioconductor.org/packages/2.3/bioc/bin/windows/contrib/2.8/ABar ray_1.10.0.zip ",file="target.zip") P.S. How should the 'file' option in getURL function be specified? Many thanks! --- LiGang [[alternative HTML version deleted]]
