How about trying a nested subset: submydf = subset(subset(mydf, a > 1),b <= a)

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.
