R help - Jan 2011 - Basic Stars Plot - help ..

Hi there Rers

I am trying a very basic stars plot:

x<-matrix(c(1,4,3,1.1,2,3,4,3,1,1,5,2), ncol = 3, byrow =
TRUE,
>>
dimnames=list(c("a","b","c","d"),c("x","y","z")))
>
> stars(x, draw.segments = TRUE, radius=TRUE)
>

Can anyone explain what I am seeing there - EACH of my plots should have 3
coloured sectors no ? - for x, y and z.  How come I am seeing only two
sectors?  Also the length of the radii show the ratio compared to the other
values of the columns (e.g. "x"), correct ? (And there is no direct
relationship between the values of a single row, or is there?)

I am using R 1.12.1 for Linux,

Many Thanks
JP

I guess you forgot the auto-scaling is done scaling the radii to [0,1] 
for the three columns of the matrix.
