将编码应用于整个数据表 [英] Apply Encoding to Entire Data.Table

问题描述

我将以下文件读入data.table中，就像这样：

I have the following file read into a data.table like so:

raw <- fread("avito_train.tsv", nrows=1000)

然后，如果我更改特定列和行的编码，例如此：

Then, if I change the encoding of a particular column and row like this:

Encoding(raw$title[2]) <- "UTF-8"

它完美地工作。

但是，如何将编码应用于所有列和所有行？

But, how can I apply the encoding to all columns, and all rows?

我检查了 fread 文档，但似乎没有任何编码选项。另外，我尝试了 Encoding（raw），但是这给了我一个错误（可能是字符向量参数）。

I checked the fread documentation but there doesn't appear to be any encoding option. Also, I tried Encoding(raw) but that gives me an error (a character vector argument expected).

推荐答案

我尝试过：

Encoding(raw$title) <- "UTF-8"

设置整个列的编码。现在可以正常工作。仍然对其他任何选项开放，因此它将在导入时自动执行。

Which sets the encoding for the entire column. That will work fine for now. Still open to any other options so it will do this automatically upon import.
