get string without ending in R
To get a string without ending in "R" using the R programming language, you can follow these steps:
- Start by defining a string variable that contains the desired string.
- Use the
substr()
function to extract all characters from the string except for the last character. - Assign the result of the
substr()
function to a new variable. - Print or use the new variable to verify that the string no longer ends with "R".
Here's an example code snippet that demonstrates these steps:
# Step 1: Define the original string
original_string <- "Hello WorldR"
# Step 2: Remove the last character using substr()
new_string <- substr(original_string, 1, nchar(original_string)-1)
# Step 3: Print or use the new string
print(new_string)
In this example, the original string is "Hello WorldR." After applying the substr()
function, the new string will be "Hello World".
