polygonize: Error in vapply(lst, class, rep(NA_character_, 3)) : values must be length 3, but FUN(X[[1]]) result is length 1 #12

If running the example code in spex::polygonize(), you get the following error:

library(sf)
library(spex)
library(raster)
r <- raster(volcano)
r[sample(ncell(r), 3000)] <- NA
b <- brick(r, r*1.5)
psf <- qm_rasterToPolygons(r, na.rm = TRUE)
psf
Error in vapply(lst, class, rep(NA_character_, 3)) : 
  values must be length 3,
 but FUN(X[[1]]) result is length 1

This is true also for other rasters when trying to polygonize() them.

Still get this! Any idea what is causing it?

mdsumner commented 6 years ago

Can you try now from master? (Please also first give a sessionInfo() so there's a record of the env you saw this)

I can't reproduce, and that vapply is sf code

adrfantini commented 6 years ago

It's fixed!
