String pad to the column in R

String pad to the column in R, padding the string to the left, right, or on either side of the column can be done in three ways. We’ll look at how to do it in this lesson.

In R, add a padding string to the left of the column.

In R, add a padding string to the right of the column.

In R, pad the string to the left and right (on both sides) of the column.

Let’s start by making the dataframe.

df<-data.frame(State = c('Kerala','TN', 'AP','HYD','GOA'),
Score=c(622,247,455,174,321))
df

   State Score
1 Kerala   622
2     TN   247
3     AP   455
4    HYD   174
5    GOA   321

Pad String to the left of the column with the width and pad arguments in the R str_pad function pads “#” to the column. The default setting will be left.

String pad to the left column

library(stringr)
df$StateNew<-str_pad(df$State,width=12,pad="#")
df

As a result, the final data frame will be

  State Score     StateNew
1 Kerala   622 ######Kerala
2     TN   247 ##########TN
3     AP   455 ##########AP
4    HYD   174 #########HYD
5    GOA   321 #########GOA

String pad to the right column

Pads “#” to the right side of the column in R str pad function with width and pad arguments and side=”right.”

library(stringr)
df$Staterighte<-str_pad(df$State,width=12,side="right",pad="#")
df

  State Score     StateNew  Staterighte
1 Kerala   622 ######Kerala Kerala######
2     TN   247 ##########TN TN##########
3     AP   455 ##########AP AP##########
4    HYD   174 #########HYD HYD#########
5    GOA   321 #########GOA GOA#########

String pad to the left and right column

With the width and pad arguments and side=”both,” the str pad function pads “#” to both sides of the column.

library(stringr)
df$Stateboth<-str_pad(df$State,width=12,side="both",pad="#")
df

  State Score     StateNew  Staterighte    Stateboth
1 Kerala   622 ######Kerala Kerala###### ###Kerala###
2     TN   247 ##########TN TN########## #####TN#####
3     AP   455 ##########AP AP########## #####AP#####
4    HYD   174 #########HYD HYD######### ####HYD#####
5    GOA   321 #########GOA GOA######### ####GOA#####
