Hi all,
I have a data frame with huge rows and columns.
When I looked at the data, it has several garbage values need to be
cleaned. For a sample I am showing you the frequency distribution
of one variables
Var1 Freq
1 : 3
2 ] 6
3 MSN 1040
4 YYZ 300
5 \\ 4
6 + 3
7. ?> 15
and continues.
I want to keep those rows that contain only a valid variable value
In this case MSN and YYZ. I tried the following
*test <- dat[dat$Var1 == "YYZ" | dat$Var1 =="MSN" ,]*
but I am not getting the desired result.
I have
Any help or idea?
