h_grid: Generate grid of plausible bandwidths for condensed summary.

In hadley/bigvis: Tools for visualisation of big data sets

Description

By default, the bandwidths start at the bin width, and then continue up 50 (n) steps until 20 (max) times the bin width.

Usage

h_grid(x, n = 50, max = 20)

Arguments

x	a condensed summary
n	number of bandwidths to generate (in each dimension)
max	maximum bandwidth to generate, as multiple of binwidth.

See Also

Other bandwidth estimation functions: best_h; rmse_cv, rmse_cvs

Examples

x <- rchallenge(1e4)
xsum <- condense(bin(x, 1 / 10))
h_grid(xsum)

y <- runif(1e4)
xysum <- condense(bin(x, 1 / 10), bin(y, 1 / 100))
h_grid(xysum, n = 10)
