View source: R/matchIndices.R

Matches two vectors with different lengths based on their maximum value.

1	matchIndices(x, y, z)

`x`	Target numeric vector.
`y`	Reference numeric vector.
`z`	A numeric element.

Uses Dynamic Time Wrapping (DTW) to match x and y. z determines the buffer size - expressed in number of data points - used to search for matching records.

A list with selected indices for x and y.

{

x <- c(2200, 4500, 4600, 6400, 1600) # target
y <- c(1100, 1150, 1200, 6400, 1600) # reference

i <- matchIndices(x, y, 1) # find best match

# plot x (blue), and selected y (red)
plot(1:5, replicate(5,0), ylim=c(0,10000), type="l") 
lines(i$x, x[i$x], type="l", col="blue")
lines(i$y, y[i$y], type="l", col="red")
