Returns the path to a small file installed with blueterra.
Usage
blueterra_example(
name = c("hitw", "hoyo", "slope", "sampling_rectangles", "bathy", "zones", "sites",
"synthetic_bathy", "synthetic_zones")
)
blueterra_examples()
blueterra_extdata(file = NULL)Arguments
- name
Example name. Use
"hitw","hoyo", or"slope"for reduced bathymetry rasters from the southwest Puerto Rico shelf margin near La Parguera;"sampling_rectangles"for the accompanying vector layer;"bathy"and"zones"as short aliases; or"synthetic_bathy"and"synthetic_zones"for test fixtures.- file
File name under
inst/extdata.
Value
A normalized local file path.
blueterra_examples() returns a tibble describing installed example
files.
Details
The primary examples are reduced analysis rasters and sampling rectangles from the southwest Puerto Rico shelf margin near La Parguera. The synthetic files are retained for numerical tests where a simple known surface is useful.
Examples
hitw <- blueterra_example("hitw")
rectangles <- blueterra_example("sampling_rectangles")
