Plot of the factorial maps of a correlation circle
performs the scatter diagram of a correlation circle.
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)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 |
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 |
possub |
a string of characters indicating the sub-title position ("topleft", "topright", "bottomleft", "bottomright") |
cgrid |
a character size, parameter used with par("cex")* |
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 |
The matched call.
