How to remove percentage sign at last position from every value in R data frame column?

To remove percentage sign at last position from every value in R data frame column, we can follow the below steps −

• First of all, create a data frame with a column having percent sign at last position in every value.

• Then, use gsub function to remove the percent sign at last position from every value in the column.

Example

Create the data frame

Let’s create a data frame as shown below −

var<-sample(c("5%","10%","1%","6%","7%","12%"),25,replace=TRUE)
df<-data.frame(var)
df

Output

On executing, the above script generates the below output(this output will vary on your system due to randomization) −

   var
1  10%
2  12%
3   1%
4   1%
5   6%
6   5%
7   7%
8   5%
9   1%
10  6%
11 10%
12 10%
13 12%
14 10%
15 10%
16  5%
17  6%
18 12%
19 7%
20  6%
21 10%
22 12%
23  7%
24 10%
25 1%

Remove percentage sign from last position

Using gsub function to remove the percentage sign at last position from every value in column var of data frame df as shown below −

var<-sample(c("5%","10%","1%","6%","7%","12%"),25,replace=TRUE)
df<-data.frame(var)
df$new_var<-gsub("%$","",df$var)
df

Output

   var new_var
1  10% 10
2  12% 12
3   1%  1
4   1%  1
5   6%  6
