title: Read.csv: some rows are missing
body: <p>I use: </p>
  
  <pre><code>read.csv('....csv', as.is=TRUE, header=TRUE)
  </code></pre>
  
  <p>There is a header in the first row and without that row there are still 72139 rows but I can only read 72138 rows. And I cannot figure out why R automatically omits a row.</p>
  
  <p>I checked the first few rows and there is no problem with them.</p>
  
  <p>Updated:
  I tried another similar csv and R missed more than 10000 row......then i found my answer here...<a href="https://stackoverflow.com/questions/26094584/read-csv-in-r-doesnt-import-all-rows-from-csv-file">read.csv in R doesn&#39;t import all rows from csv file</a></p>
  
  <p>I use quote="" in my read.csv() but then you have to be careful with your character variables.</p>
  
  <p>I am still curious since some other csv files also have double quote but with fewer rows(approximately 30000) but I never had any mistake with them before...can anyone help me with this question?</p>
  
  <p>thanks</p>
