How to Check if String is Empty in R - Step by Step Examples

How to Check if String is Empty in R ?

To check if a string is empty in R, you can use the nchar function to get the number of characters in the string.

In this example,

str1 <- ""
isEmpty <- nchar(str1) == 0
print(paste("Is string empty:", isEmpty))

[1] "Is string empty: TRUE"

In this example,

We create a variable named str2 with a non-empty string value "Hello World".
We use the nchar function on str2 to get the number of characters.
If the number of characters is 0, the string is empty.
Finally, we print the result to the console.

str2 <- "Hello World"
isEmpty <- nchar(str2) == 0
print(paste("Is string empty:", isEmpty))

[1] "Is string empty: FALSE"

In this tutorial, we learned How to Check if String is Empty in R language with well detailed examples.
