You need to tell us what compare() in S-PLUS does; i.e., what does it take

Telling us what the function looks like in S-PLUS is of no use, since most
likely the code cannot be used in R

I have codes as follows to get the ecdf plots:
day.hos2-c(6,4,6,6,4,6,5,4,7,5,6,6,8,6,17,9,8,4,6,3,5,8,7,12,5,10,6,4,6
,13,7,6,6,25,4,9,96,6,6,6,6,9,4,5,5,4,10,5,7,6)
day.hos3-c(5,6,7,6,4,5,6,6,6,6,19,7,5,9,8,8,7,5,6,20,40,5,8,7,7,5,6,13,
Yes, you're exactly right. You can use the mcmcsamp() function to sample from
the posterior of an lmer object. This returns an object of mcmc class and you
can do all of your diagnostics using the coda package.

Hi,
How can I accomplish this in R. Example:
R1 R2
3 101
4 102
3 102
18102
11101
I want to find Sum(101) = 14 - i.e SUM(R1) where R2 = 101
Sum(102) = 25- SUM(R2) where R2 = 102
TIA
Sachin
Using the built in data.frame iris sum each of the first 4 columns for
each value of the 5th column.
rowsum(iris[,-5], iris[,5])

Thanx Marc and Gabor for your help.

This worked for my example data frame but not when I used it on my
actual data frame because some of the levels of x have only one element.
However, when I replace 'sample' with 'some' (from the car package),
it works like a charm!
Many thanks to Andy and Gabor for their help!

Liaw,
Hi everyone,
I'd like to project two pcas onto one device window.
I plot my first PCA:
biplot(prcomp(t(cerebdevmat)), var.axes=FALSE, cex=c(1,.1),
pc.biplot=TRUE)
Now I'd like to project the features of another PCA onto this graph.
Any suggestions?
I know this is easily done in MatLab
