How to download file from internet via R

Question

I have an url, and I want to download the file via R, I notice that download.file would be helpful, but my problem seems different:

Answer 1

Setting the mode might be required to treat the file as binary data while saving it. If I leave that argument out, I get a blank file, but this way works for me:

url <- "http://journal.gucas.ac.cn/CN/article/downloadArticleFile.do?
attachType=PDF&id=11771"
destfile <- "myfile.pdf"
download.file(url, destfile, mode="wb")
