title: DPLYR filter- why do i get error with object? Error in filter_impl(.data, quo) : Evaluation error: object 'Email' not found
body: <p>I'm trying to filter email accounts that contain the domain "gmail"</p>
  
  <p>here's how it goes:</p>
  
  <pre><code>library(dplyr)
  GMAIL&lt;- read.csv(file.choose())
  GMAIL &lt;- data.frame(lapply(GMAIL, as.character), stringsAsFactors=FALSE)
  GMAIL2&lt;-GMAIL
  GMAIL2 %&gt;%
  filter(Email, contains("gmail"))
  </code></pre>
  
  <p>the error i get is:
  Error in filter_impl(.data, quo) : 
    Evaluation error: object 'Email' not found.</p>
  
  <p>And my Data "GMAIL" only has one column named "Email"</p>
  
  <p>I would also like to make a new dataset with the filtering result, how can I also accomplish this?</p>
  
  <p>Thx in advance</p>
