 
I guess I will just get over my laziness and use the rep function instead! But my goal was more to point out the weird names attribution behaviour. 
 
I'm using named vectors of dates that can be associated to 2 stages (incubation and rearing in nesting birds) to overlay a vector of observed data and a vector of theoritical data to see if the stages match on same dates. A data frame could also be used for this task, but I thought that vectors are a bit simpler and faster to create.
