Initialize a map with a specific extent

Source: R/mf_init.R
mf_init.Rd

Plot an invisible layer with the extent of a spatial object.
Always use add = TRUE in mf_map calls following an mf_init call. This function is similar to mf_map(x, col = NA, border = NA).

Usage

mf_init(x, expandBB = rep(0, 4))

Arguments

x

object of class sf, sfc or SpatRaster

expandBB

fractional values to expand the bounding box with, in each direction (bottom, left, top, right)

Value

No return value, a map is initiated.

Examples

mtq <- mf_get_mtq()
target <- mtq[30, ]
mf_init(target)
mf_map(mtq, add = TRUE)
