[R] Memory limitation in GeoR - Windows or R?

[Edzer J. Pebesma]

Usually, with that many observations, you use
kriging in a local neighbourhood, i.e. use only the
n nearest observations in a kriging system. If n is
pretty large, this is practically equivalent to kriging
with a global neighbourhood.

There are several other R packages that provide kriging,
some of which provide local kriging, e.g. gstat does
not require calculation of the full distance matrix.
