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

Value

The matched call.

Examples

```if(!adegraphicsLoaded()) {
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)
par(mfrow = c(1, 1))
}```
