concatenate,adp-method {oce} | R Documentation |
This function concatenates adp objects. It is intended
for objects holding data sampled through time, and it works by pasting
together data linearly if they are vectors, by row if they are matrices,
and by second index if they are arrays. It has been tested for the following
classes:
adp-class
,
adv-class
,
ctd-class
,
and
met-class
. It may do useful things for other classes, and
so users are encouraged to try, and to report problems to the developers.
It is unlikely that the function will do anything even remotely useful
for image and topographic data, to name just two cases that do not fit
the sampled-over-time category.

## 1. Split, then recombine, a ctd object. data(ctd) ctd1 <- subset(ctd, scan <= median(ctd[["scan"]])) ctd2 <- subset(ctd, scan > median(ctd[["scan"]])) CTD <- concatenate(ctd1, ctd2) ## 2. Split, then recombine, an adp object. data(adp) midtime <- median(adp[["time"]]) adp1 <- subset(adp, time <= midtime) adp2 <- subset(adp, time > midtime) ADP <- concatenate(adp1, adp2) ## Not run: ## 3. Download two met files and combine them. met1 <- read.met(download.met(id=6358, year=2003, month=8)) met2 <- read.met(download.met(id=6358, year=2003, month=9)) MET <- concatenate(met1, met2) ## End(Not run)
