title: Joining xts objects using try fails in R
body: <p>My aim is to download stock prices using the quantmod library for a large number of ticker symbols (~700) and merge the results in a single dataframe which I will save as a csv file.  I have a list of ticker symbols but not all of them are downloadable by quantmod.</p>
  
  <p>So when I pass the list with the ticker symbols to the getSymbols() method, once it encounters a problem with a particular ticker symbol it stops and returns an exception.  I am trying to circumvent this behavior with a for loop and the try method, but I fail.</p>
  
  <p>Let's look at some code:</p>
  
  <p>When I try to download two ticker symbols that are downloadable and then merge them into one xts object I succeed:</p>
  
  <pre><code>library(quantmod)
  df = getSymbols('AA', from = '1993-06-01', to = '2019-04-16', auto.assign = FALSE)
  df1 = getSymbols('A', from = '1993-06-01', to = '2019-04-16', auto.assign = FALSE)
  df_all = merge(df, df1, join = 'left')
  </code></pre>

  <p>However my implementation of a combination of a for loop and try methods fails and returns bizarre (to me) results:</p>
