Hi, It is better to show the example data using ?dput().  Here, it is not clear whether the columns are character columns or lists. ##If it is the latter case dat1 - data.frame(V1=I(list(1:3, c(1,2,4), c(2,3,4,5))), V2= I(list(c(3,6,5), c(7,10,9), 2:5)))  dat1$V3 - mapply(`c`,mapply(`-`,

Re: [R] Difference between comma separated values in column

HI, I guess this should be a bit faster. #1st case dat1$V3 - lapply(seq_along(dat1$V2),function(i) c(dat1$V2[[i]][-1] - head(dat1$V1[[i]],-1), tail(dat1$V1[[i]],1))) #2nd case dat2$V3 - unlist(lapply(seq_along(lst1[,2]),function(i) paste(c(lst1[,2][[i]][-1] - head(lst1[,1][[i]], -1),

Re: [R] Difference between times

Thank you for your reply. I discovered the OlsonNames() function to get the time-zone names in my system. Rui get a warning message when using a not recognized tz. On my system this doesn't succed. I solved as follow: dt1 = as.POSIXct(2014-04-18 09.00, format=%Y-%m-%d %H.%M, tz = Europe/Rome)

Hi. I am new to POSIX and I'd like to understand the reason of this difference. dt1 = as.POSIXct(2014-03-29 09.00, format=%Y-%m-%d %H.%M) dt2 = as.POSIXct(2014-03-30 09.00, format=%Y-%m-%d %H.%M) dt2-dt1 dt1[1] 2014-03-29 09:00:00 CET dt2[1] 2014-03-30 09:00:00 CEST dt2-dt1 Time difference of

[R] Difference between two datetimes

I have a data frame with variable datetime which is of class POSIXct. Consecutive observations are separated by 30 minutes. However, some of the differences reported by R give unexpected results. For example consider the following two consecutive entries: par.dat$datetime[5944] [1] 2010-04-04

Dear all, When I run an arima(1,1,1) on an I(1) variable, y, I get different estimates to when I first difference the variable myself, e.g y2-diff(y), and then run arima(1,0,1) on y2. Shouldn't these two approaches give the same output? Any help will be much appreciated. george

Hi, Does anybody know the difference between the Lloyd and Forgy algorithms specified for R's kmeans clustering options? I know how Lloyd works, but I cannot access Forgy's paper and could not find any specific information on the web about how it really differs from Lloyd's method. I appreciate
