Examples
## Attention: calculation is currently time-consuming.
## Not run:
# A 3-dimensional example data set D1
n <- 200
x1 <- rnorm(n, 0, 1)
y1 <- rnorm(n, 0, 1)
z1 <- rnorm(n, 0, 1)
D1 <- data.frame(cbind(x1, y1, z1))
colnames(D1) <- c("x", "y", "z")
# Specification of the grid and calculation of the halfspace location depth at each grid location.
G <- gridfun(D1, grid.size=20)
G$H <- hldepth(D1, G, verbose=TRUE)
dm <- depmed(G) ## Calculation of the depth median
## End(Not run)
