Re: [R] Converting a dataframe column from string to datetime

You’re working too hard. Use this: tms <- as.POSIXct(strptime(v, "%a %b %d %H:%M:%OS %Y")) Take note of the fact that there are two types of datetime objects: POSIXct and POSIXlt. Your unlist() gave what seemed a strange result because you used on an “lt” object. Had you given it a “ct” ob

Re: [R] Converting a dataframe column from string to datetime

I think you want to use as.POSIXct to get the date value: > v<-c("Fri Feb 05 20:00:01.43000 2010","Fri Feb 05 20:00:02.274000 2010","Fri > Feb 05 20:00:02.274000 2010","Fri Feb 05 20:00:06.34000 2010") > x <- as.POSIXct(v, format= "%a %b %d %H:%M:%OS %Y") > x [1] "2010-02-05 20:00:01 EST" "2010-0
