Re: [R] Inf and NA

Take a look at this: x <- matrix(1:9, 3) x[2,2] <- Inf x[3,1] <- NA rowMeans(x * is.finite(x), na.rm = TRUE) I at first thought you could simply use x[is.finite(x)] but that looses the matrix-ness of it so instead, we use the fact that 0 * Inf = NaN which gets killed by na.rm = TRUE. Also see my

Hi all, I have a csv matrix "KT.csv" and it has Inf and NA I want to calculate the mean of each row so I use rowMeans(KT,na.rm = TRUE) but with this Inf cannot be omminted. I´m trying to use before running rowMeans(KT,na.rm = TRUE) KT<-range(KT,finite=TRUE) but it doesn´t works... Do you kno
