plotellipseinter function

Plotellipseinter

Construit l'ensemble des ellipses de confiance

plotellipseinter(mat, alpha = 0.05, coord = c(1,2), nbgroup = 1,
    moy = TRUE, eig, cex = 1, color = NULL, title = NULL,
        graph.type = c("ggplot","classic"))

Arguments

• mat: Matrix with all the points
• coord: a length 2 vector specifying the components to plot
• alpha: Confidence level of the ellipses
• nbgroup: Confidence level of the ellipses
• moy: Confidence level of the ellipses
• eig: a matrix with the component of the factor analysis (in row) and the eigenvalues, the inertia and the cumulative inertia for each component. Typically, the eig output of the construct.axes function
• cex: cf. function par in the graphics package
• color: a vector with the colors used; by default there are 35 colors defined
• title: string corresponding to the title of the graph you draw (by default NULL and a title is chosen)
• graph.type: a character that gives the type of graph used: "ggplot" or "classic"
