scatter.fca {ade4} | R Documentation

## Plot of the factorial maps for a fuzzy correspondence analysis

### Description

performs the scatter diagrams of a fuzzy correspondence analysis.

### Usage

    scatter.fca(x, xax = 1, yax = 2, clab.moda = 1, labels = names(x$tab),
        sub = NULL, csub = 2, ...)

### Arguments

`x` | an object of class `fca`
`xax` | the column number for the x-axis
`yax` | the column number for the y-axis
`clab.moda` | the character size to write the modalities
`labels` | a vector of strings of characters for the labels of the modalities
`sub` | a vector of strings of characters to be inserted as legend in each figure
`csub` | a character size for the legend, used with `par("cex")*csub`
`...` | further arguments passed to or from other methods
