To whom it may concern,

I am currently writing a program where I need to use function rep. The results I get are quite confusing. Given two vectors A and B, I want to replicate a[1] b[1] times, a[2] b[2] times and so on.
All the entries of vector B are positive integers. My problem comes from the fact that if I sum up
all the elements of B, I get a certain
value x(for example 10000). And if i calculate the length of the vector obtained after replication, I dont always get x(10000) but sometimes I get x sometimes I get 9999 instead of 10000. Has this problem been reported before? Do you need more information on my specific program. Thanks for your time and help,
Best regards,

Julien Hunt
