Displaying errors with sweave

Question

I\'m writing some R notes with Sweave and would like to show common errors. For example,

<>=
x = 5
#Case matters!
x*X
@
         


        

Answer 1

Wrap your error in a try() command. Then it will keep running:

> {print(1); try(x*X); print(2)}
[1] 1
Error in try(x * X) : object 'X' not found
[1] 2
