Correspondence Analysis Factorial Planes

Description

It plots factorial planes of a correspondence analysis

Usage

planfac(dudi, x = 1, y = 2, rotx = FALSE, roty = FALSE, roweti=row.names(dudi$li),
                        coleti=row.names(dudi$co), titre = NULL, axislabel = TRUE, col.row = "black", 
    col.col = "blue", cex = 0.8, cex.row = 0.8, cex.col = 0.8, all.point = TRUE, Trow = TRUE, 
    Tcol = TRUE, cframe = 1.2, ucal = 0, cex.global = 1, infaxes = "out")
sutil.grid(cgrid,scale=TRUE)    

Arguments

dudi object of type dudi.coa or dudi.acm
x number indentifying the factor to be used as horizontal axis. Default x=1
y number indentifying the factor to be used as vertical axis. Default y=2
rotx TRUE if you want change the sign of the horizontal coordinates. Default FALSE
roty TRUE if you want change the sign of the vertical coordinates. Default FALSE
roweti selected row points for the graphic. Default all points
coleti selected column points for the graphic. Default all points
titre graphic title
axislabel if it is TRUE the axis information is written
col.row color for row points and row labels. Default "black"
col.col color for column points and column labels. Default "blue"
cex global scale for the labels. Default cex=0.8
cex.row scale for row points and row labels. Default cex.row=0.8
cex.col scale for column points and column labels. Default cex.col=0.8
all.point If if is TRUE, all points are outlined. Default all.point=TRUE
Trow if it is TRUE the row points are outlined. Default TRUE
Tcol if it is TRUE the column points are outlined. Default TRUE
cframe scale for graphic limits
ucal quality representation threshold (percentage) in the plane . Default ucal=0
cex.global scale for the label sizes
infaxes place to put the axes information: "out","in","no". Default infaxes="out". If infaxes="out" the graphic is similar to FactoMineR graphics, otherwise the style is similar to the one in ade4, without axes information when infaxes="no"
...
cgrid
scale

Details

Plot the selected factorial plane. sutil.grid is used by planfac

Value

It graphs the factorial plane x,y using $co, $li of a "dudi" "coa" object. If ucal > 0, the function inertia.dudi is used to calculate the quality of representation on the plane
