LoadSampleData: Load Sample Data for Package Examples
Description
Loads and subsets sample data stored in the internal datasets
sampleMap and sampleTimeSeries, included with the package.
Intended for use in documentation examples instead of Load(), in order
to avoid reliance on external system dependencies like 'nco' and 'cdo' and
to reduce computation time during CRAN checks.
Array of model data with the selected start dates and lead times.
obs
Array of observational data with the selected start dates and lead
times.
lat
Vector of latitudes.
lon
Vector of longitudes.
Arguments
sdates
Character vector of start dates to include (e.g.,
c("19851101", "19901101")). Must match one or more of the available
dates in the internal sample datasets: "19851101", "19901101", "19951101",
"20001101" or "20051101".
leadtimemin
Integer specifying the first lead time to include. Default
is 1.
leadtimemax
Integer specifying the last lead time to include. If NULL,
the full lead time range is included. Default is NULL.
output
Character string indicating the type of output: "areave"
for area-averaged time series data, or "lonlat" for gridded spatial
data. Default is "areave".
Details
This function is designed for use in examples and tests within the
's2dv' package. It provides quick access to precomputed datasets, helping to
avoid slow or system-dependent operations during automated checks.
