如何避免在每个 Sexpr{} 中使用 round()? [英] How to avoid using round() in every Sexpr{}?

问题描述

在使用 Sweave/knitr 时，有没有办法避免函数 round()?在每个 Sexpr{} 中写 round(,2) 真的很烦人.我希望整个文档保留两位小数.

Is there a way to avoid the function round() when using Sweave/knitr? It's really annoying to write round(,2) in every Sexpr{}. I would like to have two decimal places through the whole document.

如果你读过动机knitr 包的a>，你大概知道我是最讨厌的人round() 在 Sexpr{} 中最多.我很久以前就向 R core 建议过 Sweave，但它被忽略了，所以我开始了自己的包.

If you have read the motivation of the knitr package, you probably know I'm the person who hates round() inside Sexpr{} most. I suggested this to R core long time ago for Sweave but it was ignored, so I started my own package.

虽然 Josh O'Brien 的回答是绝对正确的，但我应该说你真的只需要 options(digits = 2) 和 knitr，没有必要重置默认内联挂钩，因为默认挂钩尊重此选项.

Although the answer by Josh O'Brien is absolutely correct, I should say you really only need options(digits = 2) with knitr, and there is no need to reset the default inline hook because the default hook respects this option.
