I have a column called Region in a data frame which is of character type. It has certain junk values as below which I want to remove:
"#VALUE!","10.1","10.2","138","145","161"
But when I try to remove using things like subset they don't get removed as follows:
subset(pro_202_data,Region != c("#VALUE!","10.1","10.2","138","145","161"))
I have tried using only !=
but that also doesn't work.
Please help.
Does this answer, I've created a dataframe with what you've provided and tried to filter out first two rows, you can try similarly for your entire dataframe.
> pro_202_data
Region
1 #VALUE!
2 10.1
3 10.2
4 138
5 145
6 161
> subset(pro_202_data, !(Region %in% c("#VALUE!","10.1")))
Region
3 10.2
4 138
5 145
6 161

You can subset like this:
Single vector:
x <- c("#VALUE!","10.1","10.2","138","145","161")
x[!x=="#VALUE!"]
[1] "10.1" "10.2" "138" "145" "161"
Dataframe:
df <- data.frame(
Region = c("#VALUE!","10.1","10.2","138","145","161"), stringsAsFactors = F
)
df[!df$Region=="#VALUE!",]
[1] "10.1" "10.2" "138" "145" "161"
Note the addition of the ,
to select all columns of the dataframe.
