R expression actor introduces leading/trailing whitespace
When a temporary file is used for caching length R commands, leading whitespace is being added. The list values: "OB", "BH", "CF" would become " OB", " BH", and " CF" when 'scan'ed back into the R environment.

Added the "strip.white=TRUE" parameter to calls to the scan() method in the R code we generate when dealing with character strings. According to R documentation this is used when the "sep" parameter is included (which is the case with our comma-delimited lists).
