Correlation circle
This function produces a correlation circle.
s.corcircle(dfxy, xax = 1, yax = 2, labels = row.names(as.data.frame(dfxy)), fullcircle = TRUE, facets = NULL, plot = TRUE, storeData = TRUE, add = FALSE, pos = -1, ...)
dfxy |

labels |
a vector containing the points' labels |
xax |
an integer (or a vector) indicating which column(s) of |
yax |
an integer (or a vector) indicating which column(s) of |
fullcircle |
a logical to include the complete circle (limits are then c(-1, 1)) |
facets |
a factor splitting the rows of |

a logical indicating if the graphics is displayed |
storeData |
a logical indicating if the data should be stored in
the returned object. If |

An object of class ADEg (subclass S2.corcircle) or ADEgS (if add is TRUE and/or
if facets or vectors for xax/yax are used).
The result is displayed if plot is TRUE.
