title: How to find and replace double quotes in R data frame
body: <p>I have a data frame that looks like this (sorry, I can't replicate the actual data frame with code as the double quotes don't show up. Vx are variables):</p>
  
  <pre><code>V1, V2, V3, V4
  home,   15, "grand",    terminal,
  "give", 32, "cuz",  good,
  "miles",    5,  "before",   ten,
  yes,    45, "sorry,"    fine
  </code></pre>
  
  <p>Question: how I might be able to fix the double quote issue for my entire data frame that I've imported using the read.csv function, where all the double quotes are removed? </p>
  
  <p>What I'm looking for is the excel or word equivalent of FIND + REPLACE: Find the double quote, and replace with nothing. </p>
  
  <p>Notes:
  1) I've confirmed it's a data frame by running is.data.frame() function
  2) The actual data frame has hundreds of columns, so going through each one and declaring the type of column it is isn't feasible
  3) I tried using the following, and it didn't work: <code>as.data.frame(sapply(my_data, function(x) gsub("\"", "", x)))</code>
  4) I confirmed that this isn't a simple print issue by testing using  sql on the the data frame. It won't find columns in double quotes unless I use LIKE instead of = </p>
  
  <p>Thanks in advance!</p>
