Hi there,

I have a dataframe length.unique.info
> length.unique.info
abc 12  345
def  16  550
lmn  6   600
I want those names that fall under the condition (length.unique.info[,2][i]
<=5 && length.unique.info[,3][i] >=500)

abcder<-length.unique.info[which(length.unique.info[,2][i] <=5 &&
length.unique.info[,3][i] >= 500),1]

will "&&" look for both the condition.It isnt returning names is there
anything i am missing.Kindly suggest me the way to do it.

Regards
Ramya
