Download multiple files using “download.file” function

Question

I am trying to download PDFs from a website using R.

I have a vector of the PDF-URLs (pdfurls) and a vector of destination file names (destinations

Answer 1

I think your loop is mostly fine, except you forgot to index the urls and destinations objects.

Tangentially, I would recommend getting in the habit of using seq_along instead of 1:length() when defining for loops.

for(i in seq_along(urls)){
    download.file(urls[i], destinations[i], mode="wb")
}

Or using Map as suggested by @docendodiscimus :

Map(function(u, d) download.file(u, d, mode="wb"), urls, destinations)
