Deprecated - Initialize a map with a specific extent

Description

This function is deprecated. Please use mf_map(x, col = NA, border = NA) instead.

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), extent = x, bgc)

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)
`extent`	object with an st_bbox method to define plot extent; defaults to x. extent and x must use the same CRS.

Value

No return value, a map is initiated.

Examples

mtq <- mf_get_mtq()
target <- mtq[30, ]
mf_map(target, type = "base", col = NA, border = NA)
mf_map(mtq, add = TRUE)
# or
mf_map(mtq, extent = target)
