Dear friends. I am using the command plot (inside the anacor package) to construct one simple correspondence analysis graphic. The line that I am using is this: plot(COL, plot.type = "jointplot", arrows = "FALSE", conf=NULL, xlim c(-2.5,1.5), ylim = c(-1.2,3), col.r="BLUE", col.c="BLACK") An error message appears, saying that also "col.r" as "col.c" are not a graphical parameter. Do you know what I am doing wrong? Also, I want to change the colors and shape of the simbols and the location of the labels, do you know the arguments that I need to use in this package? Thank you very much!! Claudia -- Claudia Isabel RodrÃguez Flores [[alternative HTML version deleted]]
