Examples

Run this code
# Create an array from R
file_path <- tempfile(fileext = '.nc')
a <- array(1:9, dim = c(member = 3, time = 3))
# Store into a NetCDF twice, as two different variables
ArrayToNc(list(var_1 = a, var_2 = a + 1), file_path)
# Read the dimensions and variables in the created file
fnc <- NcOpen(file_path)
fnc_dims <- NcReadDims(fnc)
var_names <- NcReadVarNames(fnc)
# Read the two variables from the file into an R array
a_from_file <- NcToArray(fnc, vars_to_read = var_names)
NcClose(fnc)
# Check the obtained array matches the original array
print(a)
print(a_from_file[1, , ])
