netcdf_create_from_list: Create NetCDF File from R list

Description

Internal function that creates a NetCDF file given a list.

Usage

netcdf_create_from_list(filename, variables, time_dim, coord_dim, value_column = "value", guess_time = FALSE, guess_coord = FALSE, verbose)

Arguments

filename

a path to a NetCDF file to write the variable into, which will be overwritten if it already exists.

variables

a list

time_dim

the name of the time dimension, if one exists

coord_dim

the name of the coordinate dimension, if one exists

value_column

if any variables are data frames, which column contains the values (default: "value")

guess_time

whether to guess time dimension; this would be a numerical column in the data frame given which is not the value_column; only one such column must exist

guess_coord

whether to guess the coordinate dimension; this would be a column with varying value which is not the time or value column

verbose

if TRUE, will print variables as they are read

Value

A list of factors in extra dimensions, if any

Details

The list of variables must follow the following rules. Each element of the list must itself be one of:

1) a list with two keys; the first key must be named "values" and contains a numeric vector; the second key must be named "dimension" and contains a string giving the dimension name.

2) a data frame with a value_column column (see option 'value_column') and any number of other columns indicating one or more dimensions

3) a numeric vector of length one, with no dimensions

The name of the list elements itself is used to create the corresponding variable in the NetCDF file.
