[R] plotting POSIXct objects {was Re: Using split() several times in a row?}

Hi Gabor and Martin, Thanks very much for the information. (and Gabor for the Fold() routine included in original reply) Regarding changes, I wonder if the behavior of plot() on POSIXct objects changed also. According to Rnews Vol. 4/1, p. 31, = dp - seq(Sys.time(),len=10,by=day)

Re: [R] plotting POSIXct objects {was Re: Using split() several times in a row?}

I think you are right. Plot does seem to have changed and maybe its due to a change in plot or maybe due to a change in some routine it in turn calls. Here is another test: dd - ISOdatetime(2007, 1, 1:3, 0, 0, 0, tz = ) plot(dd, 1:3) dd.gmt - ISOdatetime(2007, 1, 1:3, 0, 0, 0, tz = GMT)
