[R] appending to a vector

Which one is more efficient? x2=c() for (i in 1:length(x)) { x2=c(x2,func(x[i])) } or x2=x for (i in 1:length(x)) { x2=func(x[i]) } where func is any function? Dirk -- View this message in context: http://r.789695.n4.nabble.com/appending-to-a-vector-tp3449109p3449109.html Sent from the R
