Hello,
I am attempting to randomly select a data of equal length from my dataset.
My dataset is of equal length each ranging from 1 to 16 rows. Since they are
of equal length, I can form a matrix of equal length and rows or concatenate
them into a data of 16n x 2 matrix where n is number of samples.  I have
reproduced small part of the data below.

Now the problem is how to select as many  samples of the same length (i.e.
16 rows) as possible from the two dataset below.  If the first is taken as
X1 and the second as X2, manually selecting from the 4th row of X1 to 3rd
row of X2 gives a data of length 16, from 5th row of X1 to 4th row of X2
gives a data of length 16, etc. This implies choosing any row from X1 and
counting 15 rows down from that to get 16 rows. I can then concatenate these
new samples to the original sample and sort them out to do my work.

Doing this random selection manually when my  dataset becomes larger may not
be good. I will be obliged should anyone suggests how I can do this in R.

Thank you

Best regards
Ogbos
