In R, I'm imported a data frame of 2,321,123 by 4 called "dataF". I converted the data frame "dataF" to a matrix
dataM <- as.matrix(dataF)
Does R have an efficient routine to treat the special elements that contain "inf" in them. For example, can you separate the rows that have "inf" elements from the matrix into a separate matrix without iterating over the entire matrix?
Also, does R have an efficient way to sort columns in a matrix?
