问题描述
在文档中，format应该执行以下操作:
From the documentation, format should do the following:
现在，如何使用以下示例:
Now how does that go along with the following example:

[1] "="
任何人都可以解释发生了什么事吗?
Can anyone explain what is going on?
我在Windows上使用R.该问题出现在R 3.3、3.4和3.5中.该问题在Linux上没有出现.
I'm using R on Windows. The problem appears in R 3.3, 3.4 and 3.5.The problem does not appear on Linux.
推荐答案
您可以尝试运行Sys.getenv("LANG")来查看当前的R环境编码是什么.假设它是UTF-8，那么看到≤是有意义的，因为这是Unicode文字\u2264的UTF-8表示形式.
You may try running Sys.getenv("LANG") to see what your current R environment encoding is. Assuming it be UTF-8, then seeing ≤ makes sense, as this is the UTF-8 representation of the Unicode literal \u2264.
注意:在我的R工具中，我得到≤作为format("\u2264")的输出，与Unicode表相比是正确的.也许您的问题中有错字.
Note: I get ≤ as the output for format("\u2264") in my R tool, which is correct as compared against the Unicode tables. Perhaps you have a typo in your question.
