oce (version 0.9-18)

read.observatory: Read observatory data file

Description

Read observatory data file, e.g. produced by VENUS

Usage

read.observatory(file, type=c("ctd"),
                debug=getOption("oceDebug"), processingLog, ...)
read.observatory.ctd(file, 
                     debug=getOption("oceDebug"), processingLog, ...)

Arguments

file

a connection or a character string giving the name of the file to load.

type

type of data; must be "ctd", the only type handled at present.

debug

a flag that turns on debugging. Set to 1 to get a moderate amount of debugging information, or to 2 to get more.

processingLog

if provided, the action item to be stored in the log. (Typically only provided for internal calls; the default that it provides is better for normal calls by a user.)

...

additional arguments, passed to called routines.

Value

• An object of class "ctd".

Details

These are a preliminary versions of functions that may be extended or deleted in a future version of Oce. Part of the uncertainty is that the format was inferred from inspection of files, and this is always a dangerous path (compared to following lear documentation on file formats) because the data archiver might alter formats in future.

Examples

library(oce)
ctd <- read.oce("data.txt")
## mooring data are not profiles, so show timeseries
par(mfrow=c(3,1))
oce.plot.ts(ctd[["time"]], ctd[["pressure"]])
oce.plot.ts(ctd[["time"]], ctd[["salinity"]])
oce.plot.ts(ctd[["time"]], ctd[["temperature"]])
