tikzTest() fails #173

Closed elumbella closed 6 years ago

elumbella commented 6 years ago

I'm trying to create a tikz plot inside R. Sadly, that fails. Running tikzText() on my variable fails although it is only a vector containing strings with no special characters. The result is posted below.

Please let me know if you need additional information
