title: R package grid disappeared?
body: <p>R package <code>grid</code> seems to be part of some recent answers here (<a href="https://stackoverflow.com/a/29346910/684229">https://stackoverflow.com/a/29346910/684229</a> or <a href="https://gis.stackexchange.com/a/62772/4630">https://gis.stackexchange.com/a/62772/4630</a>). However, R refuses to install the package and at <a href="http://cran.r-project.org/web/packages/grid/index.html" rel="noreferrer">http://cran.r-project.org/web/packages/grid/index.html</a> I learn that grid package was removed from CRAN repository! With no other information where all its features can be found... I doubt it simply got lost without a replacement?</p>
