I have a simple (so simple, it's embarrassing) problem. I've imported a csv file with only two columns. The column headings are clearly indicated as such, yet when I try to specify some function in the console with reference to the column heading (e.g., table(heading)), I keep getting the error "object 'column heading' not found".
I've double-checked my spelling, etc. I'm sure there is something very simple that I'm not doing, but none of the suggestions I've found through a Google search have worked and all seem to be way too complicated.
Hope to find an answer here.
