Hi,
i have a dataframe containing some values.
for eg:-

MyDataFrame<-
Name   Age   Place
-------    ------    -----------
Aby          12        USA
Raj            25        UK
Romi        32        ENG
Amy         31        IND

My requirement what is, i have a search key word[it should search from all
the columns], that i need to find out from this dataframe. If search keyword
found , it should return that particular row and column number.

For eg:- My search keyword is "ENG".
After searching, it should return particular row & column number. Here it is
" MyDataFrame[3,3] "

Can anyone help me please ?

- Antony.

You can certainly massage those values in any paste()y expression you choose.

Have you read "An Introduction to R" (ships with every copy of R)
where these sorts of questions are answered?

There are other R tutorials on the web also, if you look.
