r - 如何在调试 session 期间跳过命令或代码行

Question

在R语言中调试时，是否可以绕过stop()并使其成为我要单步执行的代码？

myfun <-
    function(){
        browser()
        stop("any way around this?")

        print("code that i want to step through")

        TRUE
    }

myfun()

Answer 1

你可以屏蔽停止:

> myfun()
Called from: myfun()
Browse[1]> stop <- message
Browse[1]> n
debug at #4: stop("any way around this?")
Browse[2]> n
any way around this?
debug at #6: print("code that i want to step through")
Browse[2]> stop <- base::stop
Browse[2]> n
[1] "code that i want to step through"
debug at #8: [1] TRUE
Browse[2]> n
[1] TRUE
