Re: [R] Extracting last time value

There were errors in the code I posted. Here it is again. See my prior post in this thread for comments. Lines <- "Datetimevalue 2011062011:18:007 2011062011:39:009 2011062111:41:008 2011062111:40:006 20110622

: [R] Extracting last time value Here is a slight variation of ones you have already received. This also uses zoo. In the DF<- line we read it in as a data frame. In the z<- line we convert it to zoo using chron date/times (see R News 4/1 for more). We calculate the positions of duplicate

This should do it: > x <- read.table(textConnection("Datetimevalue + 2011062011:18:007 + 2011062011:39:009 + 2011062111:41:008 + 2011062111:40:006 + 2011062214:05:008 + 2011062214:06:00

I have a dataframe as follows: Datetimevalue 2011062011:18:007 2011062011:39:009 2011062111:41:008 2011062111:40:006 2011062214:05:008 2011062214:06:006 For every date, I want t
