As with many aspects of the tidyverse, its non-standard evaluation (NSE) implementation is not something entirely new, but built on top of base R. What makes this one so challenging to get your mind around, is that the Honorable Doctor Sir Lord Gener…

eval是在caller的作用域里运行传给它的代码: var x = 'outer';   (function() {     var x = 'inner';     eval('x'); // "inner"   })();   在 ES5,可以分为direct调用或者indirect调用,和是否在strict模式调用   (1,eval)('1+1')  为indirect调用,(1,eval)仍然返回一个eval函数 同样下面这些也是非直接调用: (eval, eval)('.…

var a=10,b=20; var s=a+b+((a/b)+(a+(a-b)))+(11)/a; var r=eval(s); console.log(r); 只要不报错,说明公式正确, 报错公式错误…
