See? "&": the unmarried model does elementwise comparisons (for when you are doing logical operations on vectors of the equal period, e. g. if in your example x<-c(1. 5,3. 5). the other one works just like c++'s or java's &&: it only looks at the first element of each vector (this is typically an unexpected downside), but in a typically better performing way: it looks from left to right, and as.
