make occ handle sf objects as well?

[sckott]

only if we can do without depending on sf, even in suggests, - as we avoid sp by using wicket

[sckott]

library(sf)
outer = matrix(c(0,0,10,0,10,10,0,10,0,0),ncol=2, byrow=TRUE)
hole1 = matrix(c(1,1,1,2,2,2,2,1,1,1),ncol=2, byrow=TRUE)
hole2 = matrix(c(5,5,5,6,6,6,6,5,5,5),ncol=2, byrow=TRUE)
pts = list(outer, hole1, hole2)
(pl1 = st_polygon(pts))
st_as_text(pl1) 
# gives WKT needed, but this requires sf
# and internally st_as_text requires lwgeom, which will still require sf and the hard to install stack

[sckott]

not sure this is possible without requiring sf
