knittr: non-numeric argument to binary operator
Thanks all for the responses. As Murphy would have it, after posting my query I found the problem. I had a function defined that did some value mapping and I had a stray line of code in the function. Actually a legitimate line of code that was just in the wrong place. Cheers, Mark On Sun, Apr 26, 2015 at 5:39 PM, Jeff Newmiller

Not reproducible [1], so any response likely to be a guess. However, you likely have not put everything that is in your interactive environment into the knitr document, so you are not working with the same data in those two environments.

knittr is giving me the above error. The code it is failing on is multiplying two numeric features of a data frame. I can run the code by hand and it works fine, but when I try to knit my document, knittr chokes on the same line. When kitting: Quitting from lines 161-175 (RepData_PeerAssessment2.Rmd) Error in storm_data$PROPDMG * storm_data$property_damage_cost_factor : non-numeric argument to binary operator Calls: <Anonymous> ... handle -> withCallingHandlers -> withVisible -> eval -> eval Execution halted Running the same lines manually (CTRL+Enter) from the .Rmd file:

Call me baffled. Any pointers are greatly appreciated at this point.
