Hello, I am using R version 1.8.1 on a linux machine (Suse 8.2.). I have problems to use readLines() with urls.
This seems to be a problem with our proxy-server. Downloading files work with download.file() with wget but not without: > download.file(url = "http://cran.r-project.org/src/contrib/PACKAGES";, destfile = > "test.txt", method = "wget", cacheOK = FALSE) This works! > download.file(url = "http://cran.r-project.org/src/contrib/PACKAGES";, destfile = > "test.txt", cacheOK = FALSE) This does not work! For readLines() there seems not to be the possibility to use wget. So I can only read the local pages which are accessible without proxy-server but not: > readLines(url("http://cran.r-project.org/src/contrib/PACKAGES";)) This does give the following response after 60 sec: >Error in readLines(url("http://cran.r-project.org/src/contrib/PACKAGES";), : cannot open the connection >In addition: Warning message: >unable to connect to 'cran.r-project.org' on port 80. After reading the help pages I checked the http_proxy environmental variable, which seems to be OK to me: > Sys.getenv("http_proxy") http_proxy "http://proxy.mh-hannover.de:8080/"; > Sys.getenv("no_proxy") no_proxy "" Setting the options options(download.file.method="wget") helps for download.file() but not for "readLines(). Does anybody has a further idea, how to manipulate readLines() so that it uses the proxy-server? Thank you Luzie -- Luzie U.
