Sorry for the wrong interpretation. So how to avoid that ? I mean how to
forcefully make it character vector ?
This one , the character vector vector column is showing integer. May be I
am missing any point.
df
X1.3 name
1 1 abc
2 2 def
3 3 xyz
> typeof(df[[2]])
[1] "integer"
>
>
> df[[2]]
[1] abc def xyz
Levels: abc def xyz
Thanks
