closest.pos | R Documentation |
For two vectors X
and Y
a vector of indices I
is returned,
such that length(Y)
and length(I)
coincide and X[I[j]]
is an element of X
which has minimal distance to Y[j]
, for all
j=1,...,length(Y)
.
In case that there are multiple elements with minimal distance, the smallest
index (the index of the first element with minimal distance) is returned.
closest.pos(X, Y)
X |
Vector of elements among which to find the closest one for each
element in |
Y |
Vector of elements for which to find the clostest element in |
Returns a vector of same length as X
, with indices indicating
which element in Y
is closest.
X1 <- c(1,2,3)
closest.pos(X1, 1.7)
closest.pos(X1, c(1.3,2.2))
X2 <- c(2,1,3)
closest.pos(X2, 1.5)
