s.corcircle {ade4} | R Documentation

## Plot of the factorial maps of a correlation circle

### Description

performs the scatter diagram of a correlation circle.

### Usage

    s.corcircle(dfxy, xax = 1, yax = 2, label = row.names(df),
        clabel = 1, grid = TRUE, sub = "", csub = 1, possub = "bottomleft",
        cgrid = 0, fullcircle = TRUE, box = FALSE, add.plot = FALSE)

### Arguments

`dfxy` | a data frame with two coordinates
`xax` | the column number for the x-axis
`yax` | the column number for the y-axis
`label` | a vector of strings of characters for the point labels
`clabel` | if not NULL, a character size for the labels, used with `par("cex")*clabel`
`grid` | a logical value indicating whether a grid in the background of the plot should be drawn
`sub` | a string of characters to be inserted as legend
`csub` | a character size for the legend, used with `par("cex")*csub`
`possub` | a string of characters indicating the sub-title position ("topleft", "topright", "bottomleft", "bottomright")
`cgrid` | a character size, parameter used with par("cex")*`cgrid` to indicate the mesh of the grid
`fullcircle` | a logical value indicating whether the complete circle sould be drawn
`box` | a logical value indcating whether a box should be drawn
`add.plot` | if TRUE uses the current graphics window

### Examples

    data (olympic)
    dudi1 <- dudi.pca(olympic$tab, scan = FALSE) # a normed PCA
    par(mfrow = c(2,2))
    s.corcircle(dudi1$co, lab = names(olympic$tab))
    s.corcircle(dudi1$co, cgrid = 0, full = FALSE, clab = 0.8)
    s.corcircle(dudi1$co, lab = as.character(1:11), cgrid = 2,
        full = FALSE, sub = "Correlation circle", csub = 2.5,
        possub = "bottomleft", box = TRUE)
    s.arrow(dudi1$co, clab = 1)
