The longer form is appropriateįor programming control-flow and typically preferred in if clauses. The longer form evaluates left to rightĮxamining only the first element of each vector. These notes explain how to move data between R and Excel and other Windows applications via the clipboard. Shorter form performs elementwise comparisons in much the same way asĪrithmetic operators. & and & indicate logical AND and | and || indicate logical OR. 1715 is a bill in the United States Congress. The operators, & and are generic functions: methods can be written for them individually or via the Ops (or S4 Logic, see below) group generic function. Short forms continues to do for the entire vectors and creates a vector of results and returns it. Raw vectors are handled without any coercion for, &, and xor, with these operators being applied bitwise (so is the 1s-complement). Horton is developing Oaks at Cedar Grove, an Express Series, single-family home neighborhood in South Fulton County. 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. Praise for previous editions: Gandrud has written a great outline of how a fully reproducible research project should look from start.
