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
and I cant find anything that will allow me to convert them to a date.
Step 2 - you need to convert the plain dumb text to a date. R has very sophisticated date/time handling - help(DateTimeClasses) and help(strptime) will give you a starting background. See if this makes sense to you once you've read that. my.data.frame$text.dates<-strptime(my.data.frame$text.dates,"%d/%m/%y") Cheers Jason
