I've added some examples to my above comment. My example is perhaps a little closer to 'median(x <- 10)' than you were asking for, but I think it illustrates the point that using '=' will not always have the desired result in places where '<-' would.
- hessenwolf 16y agoMy problem is that between work in work and work in startup I need to write in about 8 languages. This applies in all languages: vec1 = rnorm(100) system.time(vec1) mean(vec1) And, I can get my colleagues to fix it when I screw up, even though they are not R-heads.
- ltjohnson 16y agoYou gotta do what you gotta do, but your example probably doesn't do what you want in R. > system.time(vec1 <- rnorm(1000000)) user system elapsed 0.200 0.000 0.199 My computer takes .2 seconds to generate the million random normals and assign them to vec1. > vec1 = rnorm(1000000) > system.time(vec1) user system elapsed 0 0 0 My computer only takes 0 seconds to evaluate the existing vec1 of length one million.
- hessenwolf 16y agoAh - sorry - I was being a bit t'ick, and didn't twig the time thing. Should I require it, I will keep it in mind. Thank you.
