conplot {EMMIXskew} | R Documentation |
These functions are called by EmSkew.contours,EmSkew.filter and EmSkew.flow to plot the contours of (skew) mixture density after fitting to the data.
conplot(x, y, pro, mu, sigma, dof, delta, distr, grid = 300, nrand = 6000, levels = seq(5, 95, by = 20), col = "white") conplot2(x, y, pro, mu, sigma, dof, delta, distr, grid = 300, nrand = 6000, levels = seq(5, 95, by = 20)) conplot3(x, y, pro, mu, sigma, dof, delta, modpts,distr, grid =300, nrand = 10000, levels = seq(5, 95, by = 20)) mypanel2(x,y,...) mypanel3(x,y,...) mypanel4(x,y,...) panel.density(x, col=1,...)
x |
A vector of observations on variable x. |
y |
A vector of observations on variable y. |
pro |
A vector of mixing proportions in the (skew) mixture model. |
mu |
A matrix with each column corresponding to the mean or location vector of one mixture component. |
sigma |
An array of covariance matrices for each component of the mixture distribution. |
dof |
A vector of degrees of freedom when "distr"ibution is "mvt" or "mst". |
delta |
A matrix with each column as skew parameter vector of one component when "distr"ibution is "msn" or "mst". |
distr |
A three letter string indicating component distribution, "mvn"=normal distribution, "mvt"=t-distribution,"msn"=skew normal distribution, "mst"=skew t-ditribution. |
modpts |
The mode points. |
grid |
An integer for the number of grid points in one direction. |
nrand |
A large integer for the number of random numbers being drawn. |
levels |
A vector of contour percentage levels for the plots. It should be in the range of 0 to 100. |
col |
The colour of contour lines. |

In most case, users do not call this function directly, instead they call the function emmix.flow.
