Hi,
   
  I am trying to extract subset of data from my original data frame 
based on some condition. For example : (mydf -original data frame, submydf 
- subset dada frame)
   
  >submydf = subset(mydf, a > 1 & b <= a), 
   
  here column a contains values ranging from 0.01 to 100000. I want to 
extract only those matching condition 1 i.e a > . But when i execute 
this command it is not giving me appropriate result. The subset df - 
submydf  contains rows with 0.01 also. Please help me to resolve this 
problem.
   
  Thanks in advance.
   
  Sachin
