Hi
1. Do not post in html
2. Post example of data, preferably by dput function
3. Based on posted data explain what do you want to achieve
4. As it seems to be biological issue did you look at Bioconductor?
Cheers
Petr

Subject: [R] hi
I have a bit of trouble here to program in r. I am anew user but i
really enjoy working with it.I have a large number of variables in a
matrix that are arranged sequentially on a line (chromosome). This
order has to be maintained whatsoever. I am to develop an r algorithm
that will develop groups as follows;i) Calculate the correlation
between successive variables and correlation matrix for all the
variables
ii) if r(i) is the maximum correlation coefficient in the successive
variable correlation then my first group has variables [x(i-k ),
...x(i),... x(i+k )]. this gives me group one of size 2k+1. note that
variables are picked on that line and order is maintained.iii) we check
for remaining correlation btn successive variables relative to the
bigger correlation matrix and select other groups. these groups don't
need to be of same size and they must not overlap.i will have divided
in to disjoint groups but maintaining the order.kindly assist me see
how i can get this done, thanks
