title: Problem while reading csv with categories within quotes
body: <p>I want to read a csv where one of the columns contains quotes, and within the quotes the string contains commas.</p>
  
  <p><strong>CSV Header:</strong></p>
  
  <p>id,name,promo,categories,price,unit_price</p>
  
  <p><strong>CSV example row:</strong></p>
  
  <p>142251, TULI,,"Men√∫,Limpieza,Limpiadores,Pisos,Curadores",$ 73.65,$81.83 x Lt</p>
  
  <p><strong>I want to have a dataFrame like this:</strong></p>
  
  <p>id=142251</p>
  
  <p>name=TULI</p>
  
  <p>promo=</p>
  
  <p>categories=Men√∫,Limpieza,Limpiadores,Pisos,Curadores</p>
  
  <p>price=$ 73.65</p>
  
  <p>unit_price=$81.83 x Lt</p>
  
  <p><strong>I've tried doing data &lt;- read.csv(file="data.csv", sep=",", quote="")</strong> </p>
  
  <p>but I get "Error in read.table(file = file, header = header, sep = sep, quote = quote,  : more columns than column names" ERROR.</p>
  
  <p>I am aware that the solution will be very simple, but I cannot find the solution. Thanks in advance.</p>
