trying URL 'ftp://ftp.wcc.nrcs.usda.gov/data/snow/snow_course/table/ history/idaho/13e19.txt' ftp data connection made, file length 5026 bytes opened URL downloaded 5026 bytes ## R end.

Dear list, I am trying to download a text file from an ftp site using download.file(). I used the following code: url <- "ftp://ftp.wcc.nrcs.usda.gov/data/snow/snow_course/table/history/idaho..." dest <- "c:/test/downloadtest.txt" download.file(url, dest) I get this error message, indicating that R is unable to open the connection: trying URL 'ftp://ftp.wcc.nrcs.usda.gov/data/snow/snow_course/table/history/idaho... Error in download.file(url, dest) : ? cannot open URL 'ftp://ftp.wcc.nrcs.usda.gov/data/snow/snow_course/table/history/idaho... I'm sure there is a simple solution that allows R to open this connection, but after reading the "url" help file for an hour, I can't seem to find the solution. Is anyone willing to help me solve this problem? thanks in advance for any advice, Zack
