"nnwhich"(X, ..., k=1, method="C")
"lpp"
).
"interpreted"
or "C"
.
k
th nearest neighbour.
X
, identifying the nearest neighbour of each point.
If nnwhich(X)[2] = 4
then the nearest neighbour of
point 2 is point 4.Alternatively a matrix with one row for each point in X
and one column for each entry of k
.
method="C"
the task is performed using
code in the C language. If method="interpreted"
then the
computation is performed using interpreted R code. The R code is
much slower, but is provided for checking purposes.

X <- runiflpp(10, simplenet)
