## Plot a `Biplot` of a SelectVar class object

### Description

Plot a `Biplot` of a SelectVar class object

### Usage

    ## S4 method for signature 'SelectVar'
    Biplot(x,xlab=NULL, ylab=NULL, mainP=NULL,
    xlimi=NULL, ylimi=NULL, labelObs=TRUE,labelVars= TRUE,
    colVar= "black",colObs="black",
     pchPoints=15,Type=c("RMP","CMP","SQRT","HJ"),
     Groups=FALSE,NGroups=2 ,...)

### Arguments

`x` | DiStatis class object.
`xlab` | character for the x-label title for plot
`ylab` | character for the x-label title for plot
`mainP` | the main Biplot
`xlimi` | (vector) Bounds to x-axis
`ylimi` | (vector) Bounds to y-axis
`labelObs` | Logical. indicates whether the labels of observations are prints. Default is TRUE
`labelVars` | Logical. indicates whether the labels of variables are prints. Default is TRUE
`colVar` | character col for colours of the variables in the plot. Default is black.
`colObs` | character col for colours of the observations in the plot. Default is black.
`pchPoints` | Either an integer specifying a symbol or a single character to be used as the default in plotting points.
`Type` | type of Biplot. Options are CMP RMP SQRT or HJ.
`Groups` | Logical. If is TRUE, the variables are grouped. See `GroupProj`
`NGroups` | Only if the Groups are TRUE. Indicate the number the groups of variables.
`...` | additional parameters for plot

### Value

plotted Biplot/s of the component/s of the given SelectVar object.
