Hi,
I would like to generate a list of all subsequence of length k from an array with length n (k < n). The result should be organized in a matrix.
So the matrix should look like the following whereas each row is one of a subsequence of len k.
[a[1:k],
a[2:(k+1)]
a[3:(k+2)]
...
a[(n-k+1):n]
Is there away to do this with sapply method?
thanks,
Ron
