I have a simulation model that out puts dates in a standard dd/mm/yy format R reads this as a factor
Step 1 - you need to read it as plain dumb text first. In help(read.table), check out the "as.is" option. You probably want as.is=TRUE
Please check out argument colClasses. You want colClasses = "character' for that column. as.is is very confusing: it was for a long time incorrectly documented which did not reduce the confusion. I would like to deprecate it.
