To remove the last character of a string in R, you can use the substr function with the range from 1 to the length of the string minus 1.
In this example,
str1
with a value of 'Hello World'
.str1 <- 'Hello World'
str1 <- substr(str1, 1, nchar(str1) - 1)
cat('Modified string is: ', str1)
Modified string is: Hello Worl
In this example,
str2
with a value of 'apple'
.str2 <- 'apple'
str2 <- substr(str2, 1, nchar(str2) - 1)
cat('Modified string is: ', str2)
Modified string is: appl
