This looks like homework. We don't do homework. Certainly not when you
obviously haven't a) read the posting guide, b) asked your
professor/tutor, c) googled to see if you find something online, d) at
least made an effort to try, and e) read the posting guide.
Do all the points above and then try posting again.

Hello,
I have a data set with each column containing data like this:
row column1
1 1.2
2 NA
3 NA
4 3
5 5
6 NA
7 1.5
8 NA
9 NA
10 NA
11 3
12 NA
13 3
14 NA
15 NA
16 NA
17 NA
18 3
19 1.2
20 NA
From this I would like to extract the sequence containing at least
three rows of 3 in a row (exlcuding NAs). I would also like to have
the row numbers showing the place of the last number unequal to 3
befor the first 3 in the sequence and the place of the next number
after the last 3 in the sequence.
So in this example I would get 11 to 18 as the sequence rows and
row 7 to 19 as the rows showing the numbers before and after that
are unequal to three.
The rle does not work since it is not possible to exlude the NAs.
I hope you understand the question. All help is highly appreciated.
/Marine
