A function for raising a matrix to a power?
Hi,
Is there a function for raising a matrix to a power? For example if you like to compute A%*%A%*%A, is there an abbreviation similar to A^3?
Atte Tenkanen
> A=rbind(c(1,1),c(-1,-2))
> A
[,1] [,2]
[1,] 1 1
[2,] -1 -2
> A^3
[,1] [,2]
[1,] 1 1
[2,] -1 -8
But:
> A%*%A%*%A
[,1] [,2]
[1,] 1 2
[2,] -2 -5

Plot timer in a for loop
Hello,
This code works fine but is so fast I can't see anything but the last plot.
for (i in nrow(X)){
plot(as.numeric(d[i,])) }
I'd like to view a plot every 500 milliseconds, nrow(X) = 400. How?
Thanks

Using RSYNC for Multiple Servers
Hi all,
Am wanting to backup three servers to a AIT tape device that is connected to
a SCO 5.0.5 server.
Apart from itself, there is one other SCO 5.0.5 system and a Slackware Linux
server.
Is it possible to use RSYNC to backup all three servers from the primary SCO
server to the tape device ?
I wish to append to the tape device also for incremental backups.
Any other suggestions appreciated.
