Dear all,
I created a n*2 matrix and I want to replace the ith row with a vector. Can
anyone suggest me what is the simple way to do it? Sorry for bothering you
with such simple question. I appreciate any hints or advice.
Thanks in advance.

Hi Cassie,
If your matrix is named X, and your vector y, then:
X[i, ] - y
Please read the documentation for the extraction operator. You can
pull this up by entering the following command at the R console:

You would also probably benefit from a careful reading of this manual:
Indexing
(xx - matrix(1:4, nrow=2))
vec - 5:6
xx[2,] - vec
xx
