geo_translate: Translate geometric objects

In EhrmannS/geometr: Generate and Modify Interoperable Geometric Objects

Translate geometric objects

Description

Translate geometric objects by adding a constant in x and y dimension.

Usage

geo_translate(obj, x = NULL, y = NULL, fid = NULL, update = TRUE)

Arguments

obj	gridded(1) the object to translate.
x	numeric(1) the translation constant (offset) in x dimension.
y	numeric(1) the translation constant (offset) in y dimension.
fid	integerish(.) in case only a subset of features shall be translated, specify that here.
update	logical(1) whether or not to update the window slot after translation.

Value

geom of the mathematically translated obj.

Examples

# translate several features
geo_vis(gtGeoms$polygon, linewidth = 3)
newPoly <- geo_translate(obj = gtGeoms$polygon, x = 5, y = c(-10, 5),
                        update = FALSE)
geo_vis(geom = newPoly, linecol = "green", new = FALSE)

# translate a single feature
geo_vis(gtGeoms$polygon, linewidth = 3)
newPoly <- geo_translate(obj = gtGeoms$polygon, x = 5, fid = 2,
                        update = FALSE)
geo_vis(geom = newPoly, linecol = "green", new = FALSE)
