The longer form evaluates left to rightĮxamining only the first element of each vector. Shorter form performs elementwise comparisons in much the same way asĪrithmetic operators.
& and & indicate logical AND and | and || indicate logical OR.
Short forms continues to do for the entire vectors and creates a vector of results and returns it. While doing || if comparision resulted in true in first few elements, we can confidently say that any further validations will not change the result so it returns True. While doing &, if the comparision of first two elements resulted in false, comparing next set of elements will also result in False. Long form(& or ||) short circuits, which means if it can identify the result by just validating just the first element. This makes it easier to build and maintain R itself as well as the system libraries needed by R packages on Windows.
