    As the data size is too big I was trying to share some sample data. But later I found that a small amount of data matched perfectly but the real data does not. Here you will get the real data. The size is about 70MB..

      Your implementation of na.omit may lead to unintended side effects. As you specify it this will remove all rows where any of the columns is "NA" 

       

      Here is my result based on the data you provided. It has 3285939 rows but only 3117 rows will be left after the na.omit().

        Yeah. It removes maximum rows, but my question is if I run the script in R and PBI separately, it gives me a different result. Shouldn't it be same?
