- In R (as in other languages) you may do things in different ways. Sometimes it doesn’t matter which way you choose, but sometimes it really does. Once you’d need to extract elements from vector or matrix, another time you’d like to know the index of a specific element.
- Insert random NAs in a vector in R. July 30, 2014. By Patrick (This article was first published on Paleocave Blog » R, and kindly contributed to R-bloggers) Share Tweet. I was recently writing a function which was going to need to deal with NAs in some kind of semi-intelligent way. I wanted to test it with some fake data, meaning that I was going to need a vector with some random NAs
- I'm implementing an algorithm that involves lots of adding and removing things from sets. In R, this is slow because as far as I know, adding or removing things from a vector is slow, since the entire vector has to be re-allocated.
