I have a series of dates and times in one column. They are all in the format "%m/%d/%Y %H:%M:%S"; however, they are character values.
I have a number of problems: 1) if I use antdist$ts[1] to just examine the FIRST value of the timestamp (ts) column, it shows that there are 144873 Levels, and it should only have 1 Level with the first value of "6/1/2013 08:07:39"; how do I delete the remaining levels? 2) I need to change this column to a factor, so that I can use it in functions and graph it, etc. It's useless in this format. I think that once I can remove the levels, I can use as.Date or as.POSIXct to do this, but I need to figure out what's happening in the first part of the question. Here's the R code for just looking at the first value of the timestamp column: > antdist$ts[1] [1] 6/1/2013 08:07:39 144873 Levels: 6/1/2013 08:07:39 6/1/2013 08:07:41 6/1/2013 08:07:43 6/1/2013 08:07:45 ... 8/2/2013 11:47:51 Here's a photo of what the first few rows of the timestamp column look like using View(antdist): <http://r.789695.n4.nabble.com/file/n4687977/Capture.jpg> Thank you, thank you, thank you for your help! -- View this message in context: http://r.789695.n4.nabble.com/MULTIPLE-LEVELS-for-a-SINGLE-VALUE-in-a-dataframe-how-do-I-remove-these-tp4687977.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
