Example 1: Reproduce the Error – unexpected SPECIAL in X
This Example shows how to replicate the error message “unexpected SPECIAL in X” in R.
Let’s assume that we want to apply the %in% operator. If we just execute this operator without any other R code, the error “unexpected SPECIAL in “%in%”” occurs:
%in% # Reproducing the error # Error: unexpected SPECIAL in "%in%"
Operators such as %in% always need to be used in combination with other R codes.
Example 2: Fix the Error – unexpected SPECIAL in X
The R code below illustrates how to fix the error “unexpected SPECIAL in X”. For this, we have to add values in front and behind the %in% operator:
3 %in% 1:5 # TRUE
The RStudio console returns the logical value TRUE – looks good!
