starcoord {dprep} | R Documentation |
This function displays a star coordinates plot introduced by Kondogan (2001).
starcoord(data, main = NULL, class = FALSE, outliers=NULL, vars = 0, scale = 1, cex = 0.8, lwd = 0.25, lty = par("lty"))
data |
The dataset |
main |
The title of the plot |
class |
This logical variable is TRUE for supervised data and FALSE for unsupervised data |
outliers |
The instances to be highlighted as potential outliers |
vars |
The variables to be scaled |
scale |
The scale factor |
cex |
A numerical value giving the amount by which plotting text and symbols should be scaled. |
lwd |
The width of the lines representing the axis |
lty |
The type of the lines representing the axis |
This plot is not recommended for a large number of features (say more than 50).
