Histogram of a random vector

hist.rv shows a grid of histograms generated from random draws of the random vector argument.

# S3 method for rv
hist(
  x,
  grid = c(4, 5),
  xlim = x.range,
  main = paste(xname, "simulation"),
  freq = FALSE,
  ...
)

Arguments

x: an object
grid: a vector of two numbers, indicating the size of the grid to plot the histograms
xlim: x limits
main: main title
freq: logical; if FALSE, plots as probability density, as it should.
...: Other arguments passed on to hist
