Here’s the step-by-step process:


Example Data

Consider the following example character string in R:

x <- "heyho I am a string"      # Create a character string

Then, we also need to install and load the stringr package of the tidyverse environment to R:

install.packages("stringr")     # Install stringr R package
library("stringr")              # Load stringr R package


Example: str_trunc Function in R

In order to truncate our example string x, we can apply the str_trunc command as follows:

str_trunc(x, 10)                # Apply str_trunc function
# "heyho I..."

As you can see based on the output of the RStudio console, our character string was cut off after the 7th character and the last three characters where replaced by dots.
