## S3 method for class 'default':
crossdist(X, Y, x2, y2, \dots, method="C")
"C"
and "interpreted"
.[i,j]
entry is the distance
from the i
-th point in the first set of points
to the j
-th point in the second set of points. This is a method for the generic function crossdist
.
This function expects X
and Y
to be numeric vectors
of equal length specifying the coordinates of the first set of points.
The arguments x2
,y2
specify the coordinates of the
second set of points.
The argument method
is not normally used. It is
retained only for checking the validity of the software.
If method = "interpreted"
then the distances are
computed using interpreted R code only. If method="C"
(the default) then C code is used.
The C code is faster by a factor of 4.
