Let’s jump right to the examples…

Example 1: Reproduce the Error – unexpected ‘}’ in X

This Example illustrates how to reproduce the R programming error “unexpected ‘}’ in X”. Consider the following if statement:

if(TRUE) { "x" }}        # Reproducing the error
# Error: unexpected '}' in "if(TRUE) { "x" }}"

The RStudio console returned the error message “unexpected ‘}’ in X”.

The reason for this is that we used one curly bracket too much at the end of our code. This can easily happen when if else statements or in user-defined functions are getting more complex.

Example 2: Fix the Error – unexpected ‘}’ in X

Example 2 shows how to properly apply curly brackets in R. Compare the following syntax with the R code of Example 1:

if(TRUE) { "x" }         # Fixing the error
# [1] "x"

This time, the if statement worked fine, because we used only one curly bracket at the end of our code.
