Displaying 1 result from an estimated 1 matches for "t_mean_cdt".

correct my method of estimating mean of two POSIXlt data frames
...ach "pair". For example, the mean
of (t_start_cdt[1] and t_end_cdt[1]). The only way I could do this
is:
hi <- cbind(as.matrix(as.POSIXct(t_start_cdt)),
as.matrix(as.POSIXct(t_end_cdt)))
hi <- apply(hi, MARGIN=1, FUN=mean)
class(hi) <- c("POSIXt", "POSIXct")
t_mean_cdt <- as.POSIXlt(hi)
rm(hi)
What am I missing conceptually about POSIXlt, and what is the better method?
thanks,
Mike
