Generate a netCDF populated with data from a generator

Generate a netCDF populated with data from a generator

generate_raster(fname, varnames = c("data"), generator = stats::runif,
  nrow = 18, ncol = 36, extent = c(-180, 180, -90, 90),
  attrs = list(), append = FALSE)

Arguments

fname

of the generated netCDF
varnames

character vector of variable names to write to fname
generator

a function that will be called with no arguments to produce values to populate the variables
nrow

number of rows in the generated netCDF
ncol

number of columns in the generated netCDF
extent

vector of (xmin, xmax, ymin, ymax)
attrs

List of attributes to associate with the file, or with each variable. Each attribute is described by a list, with the following properties:

var

Variable with which the attribute is associated, or NULL for a global attribute

key
