Retrieve layer metadata from the Sequoia configuration

seq_layer.Rd

Resolves a layer key against the config defined in inst/config/seq_layers.yaml and inst/config/seq_path.yaml and returns the associated metadata: name, extension, filename, path, fullpath

Usage

seq_layer(key, verbose = FALSE)

Arguments

key

character Name of a layer key to match against the entries defined in inst/config/seq_layers.yaml. (see Details for partial matching).

verbose

logical If TRUE, display messages.

Value

A named list containing layer metadata, including:

  • key: the resolved configuration key

  • name: the layer name

  • ext: the file extension

  • family: the resolved namespace family

  • path: the base directory for the layer

  • full_path: the complete filesystem path to the layer

Details

The function resolves the input key using partial matching against the keys defined in inst/config/seq_layers.yaml.

  • If exactly one entry matches, it is selected. For example, key = "znieff1" can be used to match "v.mnhn.znieff1.poly" when this is the only key containing "znieff1".

  • If multiple entries match, the function aborts and displays the ambiguous keys, prompting the user to provide a more specific key.

Note: seq_layers.yaml is part of the package and must not be modified.

Examples

if (FALSE) { # \dontrun{
# Retrieve metadata for a layer
l <- seq_layer("parca")

l$full_path
} # }
