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

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
