| make.section {oce} | R Documentation |
Combine a series of CTD profiles together to create a section.
make.section(item, ...)
item |
either a ctd object, in which case the rest of the
arguments are other ctd objects, or a list of ctd
objects. |
... |
a list of ctd objects, either given as separate
arguments (the normal procedure) or as a list. |
The ctd stations must share identical pressure values;
use section.grid to do that.
An object of class "section" (for
details, see read.section).

read.ctd reads CTD data. section
is a sample data set.
library(oce)
data(ctd)
ctd.warmed <- ctd
ctd.warmed$data$temperature <- ctd.warmed$data$temperature + 0.5
ctd.warmed$metadata$latitude <- ctd.warmed$metadata$latitude + 0.1
section <- make.section(ctd, ctd.warmed)
summary(section)
plot(section, at=c(1,2), labels=c("Original","Warmed"))
