parameters
are not given as R arguments directly; the two methods for passing GRASS
parameters may not be mixed. The storage modes of values passed must match
those required in GRASS, so a single GRASS string must be a character vector
of length 1, a single GRASS integer must be an integer vector of length 1
(may be an integer constant such as 10L), and a single GRASS float must be
a numeric vector of length 1. For multiple values, use vectors of suitable
length.</p></dd>
