如何将数字数据转换为R中的货币? [英] How to Convert Numeric Data into Currency in R?

问题描述

搜索了Google和SO，但找不到合适的答案.我有下表:

Searched Google and SO and couldn't find a good answer. I have the following table:

      Country     Value
23    Bolivia  2575.684
71     Guyana  3584.693
125  Paraguay  3878.150
49    Ecuador  5647.638
126      Peru  6825.461
38   Colombia  7752.168
151  Suriname  9376.495
25     Brazil 11346.796
7   Argentina 11610.220
171 Venezuela 12766.725
168   Uruguay 14702.505
37      Chile 15363.098

所有值均以美元为单位-我想添加美元符号和逗号.因此，玻利维亚的价值应为$ 2,575.684.另外，是否真的需要将行名更改为1到12?如果是这样，那么简单的方法呢?

All values are in US dollars - I'd like to add in the dollar signs and the commas. Bolivia's value should therefore read $2,575.684. Also, is there any real need to change row names to 1 through 12? If so, an easy way to do so?

谢谢.

推荐答案
