extractFromNc: extractFromNc get data from a .nc file

In rossholmberg/pkgButterfly: Functions to calculate relevant local oceanographic variables based on Afan et. al

Description

extractFromNc get data from a .nc file

Usage

extractFromNc(file, data.variable, lat.varname = NULL, lon.varname = NULL,
  timeseries = NULL, time.varname = NULL, depth.varname = NULL,
  depth.dimension = NULL, depth.touse = NULL)

Arguments

file	.nc file containing chlorophyll levels for the entire area of influence
data.variable	character string corresponding to the relevant data subset within the .nc file (defaults to "chlorophyll")
lat.varname	if automatic searching doesn't work, specify a particular variable name here
lon.varname	if automatic searching doesn't work, specify a particular variable name here
timeseries	manually extracted timeseries data as "Date" class, to override automatic extraction from file
time.varname	if automatic searching doesn't work, specify a particular variable name here
depth.varname	name of depth variable in .nc file, auto matching used if NULL
depth.dimension	if a depth dimension is present, specify which dimension it is. auto-matching used if NULL
depth.touse	if a depth dimension is present, specify which value to use. default NULL will use minimum available depth

Value

A data.table, containing variables for date and chlorophyll level
