title: Opening an ASCII file using R
body: <p>I am trying to open an ASCII file in R.This file is exported from a software of thermal camera. It has temperature values of crop. I am using following code:</p>
  
  <pre><code>library(raster)
  r = raster("AA092800_1.asc") 
  plot(r)
  </code></pre>
  
  <p>but  every time i am getting follwing error 
  "not recognised as a supported file format
  Error in .rasterObjectFromFile(x, band = band, objecttype = "RasterLayer",  : 
    Cannot create a RasterLayer object from this file."</p>
  
  <p>on examining the file, i found that there are commas instead of decimal points, I replaced all the commas with decimals but still the same problem  exists. </p>
  
  <p>Please help me out.</p>
  
  <p>The ASCII file is attached herewith.<a href="https://drive.google.com/file/d/0B9ck19W85MFURnUtMXItaFJZRFU/view?usp=sharing" rel="nofollow noreferrer">original ascii file</a></p>
