title: how create a sequence of strings with different numbers in R
body: <p>I just cant figure it out how to create a vector in which the strings are constant but the numbers are not. For example: </p>
  
  <pre><code>c("raster[1]","raster[2]","raster[3]")
  </code></pre>
  
  <p>I'd like to use something like <code>seq(raster[1],raster[99], by=1)</code>, but this does not work.</p>
  
  <p>Thanks in advance.</p>
