Error in get_shape_details_internal(shape) :

[frankgalloro]

I'm getting the following error when trying to follow along with the example documented here.

Error in get_shape_details_internal(shape) : 
  trying to get slot "bbox" from an object (class "sf") that is not an S4 object

I'm currently working with a fresh install of R studio and only have the libraries either referenced in the example or the dependents of those libraries installed.

Hi @frankgalloro, could you provide a reproducible example (https://www.tidyverse.org/help/)?

Here's the reprex of the example.

library(geogrid)
library(sf)
#> Linking to GEOS 3.6.1, GDAL 2.2.3, proj.4 4.9.3
library(tmap)

input_file <- system.file("extdata", "london_LA.json", package = "geogrid")
original_shapes <- st_read(input_file) %>% st_set_crs(27700)
#> Reading layer `london_LA' from data source `C:\Program Files\R\R-3.5.1\library\geogrid\extdata\london_LA.json' using driver `GeoJSON'

original_shapes$SNAME <- substr(original_shapes$NAME, 1, 4)

par(mfrow = c(2, 3), mar = c(0, 0, 2, 0))
for (i in 1:6) {
  new_cells <- calculate_grid(shape = original_shapes, grid_type = "hexagonal", seed = i)
  plot(new_cells, main = paste("Seed", i, sep = " "))
}

@frankgalloro please install the development version (devtools::install_github("jbaileyh/geogrid") and let us know if it works now.

[frankgalloro]

The development version is working!

Can't thank you guys enough!
