title: Data loss during read.csv in R
body: <p>I have a .csv file to be imported into R, which has more than 1K observations. However, when I used the read.csv function as usual, the imported file only has 21 observations. This is strange. I've never seen this before. </p>
  
  <pre><code>t &lt;- read.csv("E:\\AH1_09182014.CSV",header=T, colClasses=c(rep("character",3),rep("numeric",22)),na.string=c("null","NaN",""),stringsAsFactors=FALSE)
  </code></pre>
  
  <p>Can anyone help me figure out the problem? I am giving a link to my data file:</p>
