[R] need to plot multiple spatial maps side-by-side in a single window using sf plot function in R

[Bert Gunter]

It seems that sp uses the lattice package and spplot() for multiple
plots. These are completely incompatible with base plot's par(mfrow
=...) multiple plotting. I think you need to study how lattice works.
In particular, see ?plot.trellis and ?xyplot for some relevant info.

You might also do better posting this on r-sig-geo,
https://stat.ethz.ch/mailman/listinfo/r-sig-geo , where expertise on
this sort of thing is more likely to reside.
