List the catalogue's themes

Source: R/catalogue.R
list_themes.Rd

Reads the short Category/Description/Examples readme in each top-level theme folder and reports it alongside the number of layers catalogued under it. Themes follow the ISO 19115 topic categories used by the data management guide. The share's _temp scratch folder is not a theme and is not listed.

Usage

list_themes(...)

Arguments

...

Passed to build_catalogue(), e.g. root or refresh.

Value

A data.frame with theme, description, examples, and n_layers, classed sciSpatial_themes so that printing it gives the same compact view list_layers() does. The full table, examples included, is there for subsetting.

list_layers().

Examples

if (FALSE) { # \dontrun{
list_themes()
} # }
