Calculate local minimum within a local neighborhood

1	localMin(vec, neighborhood)

`vec`	a vector to be evaluated for the presence of local minimum
`neighborhood`	number of points to the left and right of a point for calculating local minima (see details).

'neighborhood = 1' will detect local minima at position 'i' defind as a point that is less than both its neighbors to the left '(i-1)' and right '(i+1)'. Setting 'neighborhood > 1' results in detecting local minima at a position 'i' defined as a point that is less than all neighboring points to the left 'c(i-1, i-..., i-n)' and right 'c(i+1, i+..., i+n)'.

a logical vector masking the positions of local minima

dat <- rnorm(n = 100, mean = 0, sd = 1)
i <- seq_along(dat)
locMin <- localMin(vec = dat, neighborhood = 1)

i_locMin <- i[locMin]
locMin <-dat[locMin]

plot(x = i, y = dat); points(x = i_locMin, y = locMin, col = "red")
