I would guess the ifelse (x>0,1,0) -approach would be somewhat slower if applied to a large vector or if used in simulations. Could also use: Ivec <- 1* (vec>0) Share Improve this answer … Web7 feb. 2016 · Now consider a sequence ( x n ∣ n ∈ N) of real numbers x n. By definition lim inf n ∈ N x n = sup m ∈ N inf l ≥ m x l. We are interested in the case where x n = χ A n ( x) for some fixed x. Then lim inf n ∈ N χ A n ( x) = 1 if and only if there is some m ∈ N such that for all l ≥ m we have that inf l ≥ m χ A n ( x) = 1. criminal defense attorney westbrook
