[R] lattice: problem with cex argument.

[ernesto]

Hi,

I'm trying to plot a "bubbles" plot wich I do with the cex argument. The
problem is that it looks like it fails the conditioning and reuses the
first 100 elements of the cex vector. See the code

x <- rep(rep(1:10,10),2)
y <- rep(rep(c(1:10),rep(10,10)),2)
z <- rep(1:2,c(100,100))
w <- rpois(200,l=1)
xyplot(y~x|z, cex=w)

the plot has the same pattern in both sides but the data are different, see

> tapply(w,z,summary)
$"1"
   Min. 1st Qu.  Median    Mean 3rd Qu.    Max.
   0.00    0.00    1.00    0.99    1.00    4.00

$"2"
   Min. 1st Qu.  Median    Mean 3rd Qu.    Max.
   0.00    0.00    1.00    0.95    2.00    4.00

or the plots

par(mfrow=c(1,2))
tapply(w,z,hist)

and

xyplot(w~x|y*z)

Is this a feature or a bug ?

Regards
