Hello,
I have a sample data frame which looks like this
day od month
1 1 0.1 2
2 3 #VALUE! 1
3 5 0.4 12
4 7 0.8 10
5 11 - 3
6 14 s 7
7 18 -- 12
8 27 19 7
Now i wish to filter all the non numeric values and replace it with "NA". The
data frame is actually huge and the non numeric characters vary from "-" to a
string to absolutely anything!!!
Can anyone please help ?
Thank you,
Warm Regards,
Nandini
