"&": the unmarried version does elementwise comparisons (for when you are doing logical operations on vectors of the identical period, e. g. if on your example x<-c(1. five,three. 5). the other one works just like c++'s or java's &&: it handiest looks at the first element of every vector (that is generally an unexpected drawback), however in a commonly better performing way: it looks from left to proper, and as.
