[R] adding zeroes after old zeroes in a vector ??

[skan]

Hello

Imagine I have a vector with ones and zeroes

I write it compactly:
1111111100001111111111110000000001111111111100101

I need to get a new vector replacing the "N" ones following the zeroes to
new zeroes.

For example for N = 3
1111111100001111111111110000000001111111111100101  becomes
1111111100000001111111110000000000001111111100000

I can do it with a for loop but I've read is not a good practice,  How can I
do it then?

cheers


My vector is a zoo series, indeed, but I guess it doesn't make any
difference.
