Error message with the effects package - 'Subscript out of bounds'
...t some probability graphs showing
the predicted probabilities from a logistic regression model.
However, I get an odd error message and don't know what the issue is.
When I attempt to generate the plots, I get the following error:

Plotting every probability curve
...have permutations for all possible combinations.
I've found that I can use the TeachingDemos package (see below) to
construct a gui which makes this easier, but I want to form
curve separately so that I can save them
