将 csv 导入 r 时 a-hat 是什么意思（以及如何摆脱它）？

[英]What's an a-hat mean when importing a csv into r (and how do I get rid of it)?

问题描述

I'm importing a csv into r and there are a-hats (an a with a circumflex / up carat above it) all over the place that don't exist in the raw data.我正在将一个 csv 导入到 r 中，并且在原始数据中不存在的地方到处都是 a-hats（一个带有抑扬符/向上克拉的 a）。

Does anyone know what they are and how to get rid of them?有谁知道它们是什么以及如何摆脱它们？

Here is the dput(head(df)) result @foc suggested I supply:这是@foc 建议我提供的 dput(head(df)) 结果：

 structure(list(V1 = c("", "Race3 and Hispanic Origin", "Whiteâ\200¦â\200¦â\200¦â\200¦â\200¦â\200¦â\200¦â\200¦â\200¦â\200¦â\200¦â\200¦â\200¦â\200¦â\200¦â\200¦",
