与R中的区域设置混淆

Question

刚才我回答了在R问题中的EURO符号后删除字符.但是对于我来说,r代码适用于Ubuntu上的其他人.

这是我的代码.

x <- "services as defined in this SOW at a price of € 15,896.80 (if executed fro"
euro <- "\u20AC"
gsub(paste(euro , "(\\S+)|."), "\\1", x)
# "" 

我认为这都是关于更改区域设置,我不知道该怎么做.

我在Windows 8上运行rstudio.

@ Anada的答案很好但我们需要encoding在regex中使用unicodes时每次添加该参数.有没有办法utf-8在Windows上修改默认编码？

Answer 1

似乎是编码问题.

考虑:

x <- "services as defined in this SOW at a price of € 15,896.80 (if executed fro"
gsub(paste(euro , "(\\S+)|."), "\\1", x)
# [1] ""
gsub(paste(euro , "(\\S+)|."), "\\1", `Encoding<-`(x, "UTF8"))
# [1] "15,896.80"
