Helper to get a variable from NetCDF.

Source: R/netcdf-utils.R
nc_get.Rd

This exists so we can (internally) use a file path, uri, or open NetCDF connection (ncdf4 or RNetCDF) in a simpler way.

Usage

nc_get(x, v, test = FALSE)

Arguments

x

file path, uri, or NetCDF connection

v

variable name

test

if true we make sure the connection can be open, not applied for connections themselves

Value

array of values for the requested variable

Details

This function just reads the whole array. It is equivalent to the angstroms package function 'rawdata(x, varname)'.

Examples

l3file <- "S20080012008031.L3m_MO_CHL_chlor_a_9km.nc"
fpath <- system.file("extdata", "oceandata", l3file,
package = "tidync")
lat <- nc_get(fpath, "lat")
