"order" issue
..., and then AGAIN from max to min in the positive values!!!
Why isn't everything order from max to min, and that's it?
Thank you!!!
Attached is the txt file I use; try:
x=x[order(x[,2]),]
What I get is:

selectFGR - variable selection in fine gray model for competing risks
Dear All,
I would like to use R function 'selectFGR' of fine gray model in competing risks model. I used the 'Melanoma' data in 'riskRegression' package. Some of the variables are factor. I get solution for full model but not in variable selection model. Any advice how to use factor variable in 'selectFGR' function. The following R code is produced below for reproducibility.

plot(pam.object) error with R-1.7.0 on Red-Hat 8.0 i686
I don't know if there is some fault in compiling or a bug of the new
R-1.7.0 version:
cl.pam.2 <- pam(as.dist(1-cor(mel.data)),2)
plot(cl.pam.2)
perform a right partitioning and silhouette plot on the old R-1.6.2
instead
"Error in clusplot.default(x$diss,...... ;
x is not numeric"
is the output on the new R-1.7.0.
Same platform: RH8.0 i686.
Some suggestions?

I can't reproduce this in either R-devel or 1.8.1, and termplot hasn't
