I'm having a problem viewing a silhouette plot created as a pdf file
in Adobe Acrobat. The code below produces a silhouette plot which,
when saved as a pdf file, has bars that are not visible in Adobe
Acrobat. A similar problem was noted earlier in the archives (from
which I took this code) but for a png file. The archive emails
suggested it may have been a resolution problem however did not have a
simple workaround, which I assume may exist.
Note also that the bars of the silhouette plot below are viewable in
the MAC "preview" app.
library(cluster)
nmat <- matrix(rnorm(2500*300), ncol=300, nrow=2500)
rmat <- matrix(rchisq(1000, 300, 50), ncol=300, nrow=1000)
mat <- rbind(nmat, rmat)
pr <- pam(mat, 2)
plot(silhouette(pr))
Any help would be appreciated,
Many thanks,
Joe Retzer
