Rescale a genetic map by multiplying all positions by a constant
rescalemap(object, scale=1e-6)If the input is a map object, a map object is returned; if
the input is a cross object, a cross object is returned.
In either case, the positions of markers are simply multiplied by
scale.
An object of class cross (see
read.cross for details) or map (see
sim.map for details).
Scale factor by which all positions will be multiplied.

This function is included particularly for the case that map positions
in a cross object were provided in basepairs and one wishes to quickly
convert them to Mbp or some other approximation of cM distances. (In
the mouse, 1 cM is approximation 2 Mbp, so one might use
scale=5e-7 in this function.)
