title: Suppress All Messages/Warnings with Readr read_csv function
body: <p>I am creating a rmarkdown pdf report. I used read_csv function from readr package to import some csv files in a folder. I used SuppressMessages/Warnings functions to hide all warnings/messages, but I still get the messages as below when trying to import multiple files:</p>
  
  <p>It seems SuppressMessages/Warnings don't work on the parsing warnings.</p>
  
  <pre><code>## Parsed with column specification:
  ## cols(
  ## .default = col_character(),
  ## `Constant USD - Accrued Sum` = col_number(),
  ## `Units Sold Sum` = col_number()
  ## )
  </code></pre>
  
  <p>Because the report is aimed for non-technical audience, the warning messages can be a distraction. What can I do to keep this message from showing?</p>
