R 4.1 deprecated the use of download.file(method = 'wininet'). R 4.2 switched the default download method to 'libcurl' and started giving warnings for 'wininet' and http[s]:// URLs. A workaround to get it working right now would be to set options(download.file.method = 'wininet') and live with the resulting warnings while R downloads the files, but a next version of R may remove 'wininet' support altogether. In order to get it working with the 'libcurl' method, you'll need to provide some environment variables to curl: https://stat.ethz.ch/pipermail/r-help/2022-September/475917.html Not sure if libcurl would accept a patch to discover the Windows proxy settings automatically, but I don't think it does that now. -- Best regards, Ivan ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
