title: Download URL links using R
body: <p>I am new to R and would like to seek some advice.</p>
  
  <p>I am trying to download multiple url links (pdf format, not html) and save it into pdf file format using R.</p>
  
  <p>The links I have are in character (took from the html code of the website).</p>
  
  <p>I tried using download.file() function, but this requires specific url link (Written in R script) and therefore can only download 1 link for 1 file. However I have many url links, and would like to get help in doing this.</p>
  
  <p>Thank you.</p>
