R: plotting mass points

plotMP

R Documentation

plotting mass points

Description

A utility function for plotting two dimension non-parametric distribution. The function uses the persp() function.

Usage

plotMP(x, y, prob, theta = 20, phi = 20, expand = 0.5, col = "lightblue", 
      xlab = "intercept", ylab = "slope", ...)

Arguments

`x`	a vector containg points in the x axis
`y`	a vector containg points in the y axis
`prob`	vector containing probabilities which should add up to one
`theta, phi, expand, col`	arguments to pass to the `persp()` function
`xlab`	the x label
`ylab`	the y label
`...`	additinal argument to be passed to `persp()`

Details

  gamma_1 <- c( 2.2, 1.2, 0.1, -1, -2.3, -4.6 , 5.1, -3.2, 0.1, -1.2)
     prob <- c(0.1, .05, .12, 0.25, 0.08, 0.12, 0.10, 0.05, 0.10, 0.03 )
  plotMP(gamma_0, gamma_1,prob)
