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: > storm_data$total_damage <- + (storm_data$PROPDMG * storm_data$property_damage_cost_factor) + + (storm_data$CROPDMG * storm_data$crop_damage_cost_factor) > str(storm_data$total_damage) num [1:902297] 25 2.5 25 2.5 2.5 2.5 2.5 2.5 25 25 ... > Call me baffled. Any pointers are greatly appreciated at this point. -- Cheers, Mark Mark Drummond m...@markdrummond.ca When I get sad, I stop being sad and be Awesome instead.
