ggplot support for SpatGraticule

Maschette commented 6 days ago

Hi, This may be covered by another function but I couldn't see it in your list of data types.

Is there a way to plot SpatGraticule with ggplot2?

thanks, Dale

Currently I don't identify many methods for SpatGraticule objects, on terra so my workaround here would be converting it to SpatVector and then using geom_spatvector(), based on https://github.com/rspatial/terra/blob/43681fd1af25775ee1565a4fd1bb5b4830b1c985/R/graticule.R#L211-L212

  crs = crs(lux)
)

Maybe add vect.SpatGraticule method to terra @rhijmans ?

rhijmans commented 6 days ago

I have added a vect<SpatGraticule> method to terra 1.8-3. Thank you for suggesting it.
