Hello again Jim
It seems that ashift() from the same package *doesn't* do what you want.
But you can use shift() as follows:
> myshift <- function(x){shift(x,1-which.max(x))}
> a <- matrix(runif(30),5,6)
> a
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] 0.268955362
Hello Jim
you can use ashift() from the same library which does (I think) what you
want.

Dear List,
I have a 2,000x10,000 array of time domain data which when plotted draws
a distinct pulse. The matrix is 10,000 pulses of length 2000. I would
like the pulse to be shifted so that the peak (which.max of the pulse
data) is consistently at point 400.
I don't want to use loops as it'
