更改真假是和否 [英] Change TRUE and FALSE to Yes and No

问题描述

我有下述R脚本：

x <- c('PE', 'MG', 'SP', 'GO', 'ES', 'PB', 'DF')
y <- c('PB', 'MG', 'SP', 'GO', 'ES', 'SE', 'DF')
z <- x == y

这样

> z
[1] FALSE  TRUE  TRUE  TRUE  TRUE FALSE  TRUE

不过，我想以Z （和其他逻辑变量进一步下跌的脚本），以显示是和否来代替，所以我这样做录音：

However, I want z (and other logical variables further down the script) to show "Yes" and "No" instead, so I do this recoding:

z <- ifelse(z == TRUE, "Yes", "No")

有没有办法跳过这个额外的步骤，即定义以Z 显示是，而不是真与否，而不是假。

Is there any way to skip this extra step, i.e., define z show "Yes" instead of "TRUE" and "No" instead of "FALSE".

当然，我也可以做 z，其中; - ifelse（X == Y，是，否），但我仍然在寻找有点像选项里面的参数（）的功能，我只定义一次，有它直到脚本的工作进行到底（或直到我重新定义了参数）。无法找到这样的事情？选项。

Of course, I could also do z <- ifelse(x == y, "Yes", "No"), but I'm still looking for something like a parameter inside the options() function I could define just once and have it work until the end of the script (or until I redefined the parameter). Couldn't find anything like it on ?options.

推荐答案

据我所知是没有办法覆盖的事实，研究打印 TRUE 和 FALSE 逻辑对象（我个人认为这是很好的）。

As far as I know there is no way to overwrite the fact that R prints TRUE and FALSE for logical objects (personally I think that's good).

最近的解决方案，你要寻找的可能是因素转换：

The closest solution to what you're looking for could be factor conversion:

z <- factor(x==y, labels=c("No", "Yes"))

> z
[1] No  Yes Yes Yes Yes No  Yes
Levels: No Yes
