The script is complete. When I start, the environment is empty. The warnings are issued for these "ghost" variables well before they are created later in the script. Somehow previous incarnations are lingering around and being unhappy even after they were "deleted". Jeff Newmiller has suggested a solution I have yet to try.

However, sometimes when I re-rerun a script I get warning messages (see below for example) regarding some variables (objects) when these variables do not exist in my current environment. These ghost variables had existed at one time, but were subsequently removed by the rm(list=ls()) command or by the broom icon in RStudio. What's happening and how do I exorcise the ghosts? Warning messages: 1: Unknown or uninitialised column: 'K'. 2: Unknown or uninitialised column: 'NDAfit'. 3: Unknown or uninitialised column: 'NDAfit'. 4: Unknown or uninitialised column: 'NDAfit'. 5: Unknown or uninitialised column: 'NDAfit'. 6: Unknown or uninitialised column: 'NDAfit'. 7: Unknown or uninitialised column: 'NDAobs'.
