In R when a function is defined it captures a reference to the current execution environment. This environment is used to bind values to free variables in the function (free variables are variables whose names are not defined in the function or in the function arguments). An example is the ...
For this, we use the which function again, but this time we specify the arr.ind to be equal to TRUE: mat_pos<-which(mat==4,# Set arr.ind = TRUEarr.ind=TRUE)mat_pos# Print position matrix of value 4 The output of the previous R syntax is shown in Table 2: We have created a...
错误一:如果你忘记写def func(num):如下: for num in range(1,10): if num==5: print("I find '5'") return func(5) 则报错:SyntaxError: ‘return’ outside function 错误二:缩进错误也会报同样的错: def func(num): for num in range(1,10): if num==5: print("I find '5'") return...
We used the input values 5 and 3 and our function returned the value 8 (i.e. 5 + 3 = 8).Looks good!However, is the return command really needed? That’s what you will learn in the next example.Example 2: R Function without returnLet’s delete the return command from our function...
Error in bug() : could not find function "bug" 这里由于函数关系简单我们很容易就知道了错误的原因,但很多时候你根本不知道出错的函数是什么地方为什么被调用的,此时traceback()可以看到出错之前R函数调用的路径,并返回一个调用栈(call stack),即调用函数的有序列表。
