Moshe,
Gabor posted that same solution shortly after my reply on Thursday.
I had one of those "head banging" episodes shortly thereafter... :-)

How about adding an artificial last row containing no
1's (say a row of zeros)?

Marc and Gabor
thank you so much.
Also for making me realize how litte I know about R's potential
best,
Mario
ps I actually thought about appending that row of
zeros while waking up this morning..

We can append a row of 0's to handle that case:
with(rle(as.vector(rbind(prova, 0))), table(lengths[values == 1]))

Ah...OK. I misunderstood then. I thought that you wanted the number of
runs of 1's in each column.
This is actually easier, _if_ there is not an overlap of 1's from the
end of one column to the start of the next column:
res <- rle(as.vector(prova))
> res
Run Length Encoding
lengths: int [1:11]

Thanks Gabor. Nice solution.

I did not think about the case of overlapping of
1's from the end of one column to the start of the next,
this would actually be a problem
In the simulations I am running each column
corresponds to the path followed by an agent
across states of a stochastic process,
so I would like t
Dear Marc
thank you so much!
One thing: writing xx=[1,2,1,1] is not a typo: I
read it as the count of runs of different length starting from 1.
In "prova" I have 1 run of length one, 2 runs of
length two, 1 run of length three and 1 run of length four.
Can I abuse of your time and ask how to

Hello
I have this problem. I have a large matrix of this sort:
