Inf values in a matrix

Hello,

I have some Inf values in a matrix, but I don't want to replace them with
some value but rather remove the rows that contain the Inf values. Also I
would like to record the rows which were removed. Is there an easy way to
do this instead of writing loops over the matrix? Thanks.

  A <- matrix(1:100, 10)
  A[cbind(3:4, 5:6)] <- Inf
  recorded <- which(apply(A, 1, function(x) any(is.infinite(x))))
  A[-recorded,]
