title: R Read.table: sep when there are more than 1 occurence
body: <p>I have a big list of the format
  Variable = Value.
  99% of the list is in this format. However, very few entries need to have a = within the value part. So they look like Variable = Value = something</p>
  
  <p>So my read.table function throws an error:</p>
  
  <pre><code>Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings,  : 
    line 2 did not have 2 elements
  </code></pre>
  
  <p>Is there a way to avoid this without having to change the original file?
  This is my read table command:</p>
  
  <pre><code>VarNamesDescription&lt;-read.table(paste(FilePathVariableDescription), sep="=", skip=0, header=FALSE,stringsAsFactors=FALSE)
  </code></pre>
  
  <p>EDIT:
  Cell with one =</p>
  
  <pre><code>AABB NA=HOLDING NV
  </code></pre>
  
  <p>Cell with two =</p>
  
  <pre><code>AA=ETX Sml = PrM013)
  </code></pre>
