grd_snap_next

grd_snap_previous

These functions can be used in <code>grd_cell()</code> and
<code>grd_cell_range()</code>. These functions differ in the way
they round 0.5: <code>grd_snap_next()</code> always rounds up
and <code>grd_snap_previous()</code> always rounds down. You can
also use <code><a href="/link/floor()?package=wk&version=0.9.4" data-mini-rdoc="wk::floor()">floor()</a></code> and <code><a href="/link/ceiling()?package=wk&version=0.9.4" data-mini-rdoc="wk::ceiling()">ceiling()</a></code> as index
snap functions.

Provides a minimal R and C++ API for parsing
well-known binary and well-known text representation of
geometries to and from R-native formats.
Well-known binary is compact
and fast to parse; well-known text is human-readable
and is useful for writing tests. These formats are
useful in R only if the information they contain can be
accessed in R, for which high-performance functions
are provided here.
