title: how to use "for loop" and "write.csv" at the same time?
body: <p>I have an array. It has lat,lon,time,and value. Time starts from 1 to 300. Here is part of  array for time=1. </p>

  <p>I want to use "write.csv" and "for loop" at the same time to read the data from array for each time step (1 to 300) and store them in individual .csv files which has "i" as index. I used this command but it seems that it doesn't work:</p>
  
  <pre><code>for (i in 1:300)    write.csv(myarray[,,i],"myarray.i.csv")
  </code></pre>
