[R] replacing zeros with above/below numbers ?

[ce]

Yes , indeed this is what I am looking for :

a[ a == 0.0 ] = NA
na.approx(a,na.rm="FALSE")

Thanks a lot.

You seem to be treating zeroes as unknown values. Perhaps you should consider setting them to NA and using the na.approx function from the zoo package.
