Get layer visibility for a theme — gq_theme

Returns which layers a theme shows or hides.

Usage

gq_theme_layers(theme, template = NULL)

Arguments

theme: Character. Theme name, e.g. "High Detail - Crossings".
template: Character. Optional template name to restrict to.

Value

A data.frame with columns: template, theme, layer_key, visible. Returns an empty data.frame if the theme is not found.

Details

Without template, a theme name that ships in more than one template returns every template's rows concatenated — check the template column, or pass it, when you want one project's answer. High Detail - Crossings is the live example: it ships in both templates, so it returns 64 rows rather than 32.

Examples

# both templates come back concatenated — check the template column
xing <- gq_theme_layers("High Detail - Crossings")
table(xing$template, xing$visible)
#>                       
#>                        FALSE TRUE
#>   bcfishpass_mobile        5   27
#>   bcrestoration_mobile     5   27

# a theme only one template ships
head(gq_theme_layers("Land Tenure", template = "bcrestoration_mobile"))
#>               template       theme                        layer_key visible

#> 2 bcrestoration_mobile Land Tenure                      bing_aerial   FALSE
#> 3 bcrestoration_mobile Land Tenure                      conservancy    TRUE
