Unconnected graph crashes skater()

[rsbivand]

This will crash R:

library(sf)
columbus <- st_read(system.file("shapes/columbus.shp", package="spData"))
library(rgeoda)
columbus_43 <- columbus[columbus$NEIG != 43,]
plot(st_geometry(columbus_43), axes=TRUE)
qw <- queen_weights(columbus_43)
geoda_o <- skater(4, qw, columbus_43[,7:9])

#*** caught segfault ***
#address (nil), cause 'memory not mapped'

#Traceback:
# 1: p_skater(k, w$GetPointer(), df, n_vars, scale_method, distance_method,     bound_values, min_bound, random_seed, cpu_threads)
# 2: skater(4, qw, columbus_43[, 7:9])

I think because there is no check that the graph is connected for the minimum spanning tree step.

The code does not work correctly in the case of having unconnected regions. The skater function crashes R. Is there a plan to fix this?
