如何在R图中显示đ，ư，ơ，ă [英] how to display đ, ư, ơ, ă in R graphs

问题描述

我尝试在R图表中放置越南语标签。我使用RStudio并保存我的代码使用UTF-8编码。它处理我放在代码中的越南字符，我的意思是一切显示在代码中正确。但是，在我创建的图表中，虽然许多字符显示正常，但几个重要的字符不正确显示，包括

đ - 显示不正确d

ư - 不正确显示为u

ơ - 不正确显示为o

ă - 不正确显示为

不幸的是，这使我的图表看起来不专业，不可信。

非常感谢。

@krlmlr：这是一个简单图形的代码：

  knorelative.count < （nrow = 5，ncol = 1）
 knorelative.count [，1]<  -  c（1579,638,215,100,120）
 
 par（mar = c ）
 barplot（prop.table（knorelative.count），beside = TRUE，
 yaxt =n，ylim = c（0，.6），
 legend = c ，
nửabiết，nửakhôngbiết，
biếtnhiềuhơnkhôngbiết，
tấtcảđều，
khôngbiếtnhiềuhơnbiết b $ b轴（2，at = seq（0，.6，.1），labels = paste（100），
 main =ngờ * seq（0，.6，.1），％，sep =），las = 1）
  

当我运行这个时，主标题中的đ，以及图例中的两个Æ和đ变成d和o。

解决方案

您通常使用十六进制代码更安全地指定unicode字符：

  plot（1：4，rep （1,4），pch = c（\\\đ，\\\ư，\\\ơ，\\\ă），cex = 4）
  

I am trying to put Vietnamese labeling in R graphs. I use RStudio and save my code using UTF-8 encoding. It handles the Vietnamese characters I put in the code well, I mean everything shows up in the code properly. However, in the graphs I make, while many characters display OK, several important ones do not show up properly, including

đ - which displays incorrectly as d

ư - which displays incorrectly as u

ơ - which displays incorrectly as o

ă - which displays incorrectly as a

Unfortunately this makes my graphs look unprofessional and untrustworthy.

I would really appreciate it if someone can help me figure this out.

Thanks much!

@krlmlr: Here's my code for a simple graph:

knorelative.count <- matrix(nrow=5,ncol=1)
knorelative.count[,1] <- c(1579,638,215,100,120)

par(mar=c(2,4,4,2))
barplot(prop.table(knorelative.count),beside=TRUE,
        yaxt="n",ylim=c(0,.6),
        legend=c("không ai biết",
                 "không biết nhiều hơn biết",
                 "nửa biết, nửa không biết",
                 "biết nhiều hơn không biết",
                 "tất cả đều biết"),
        main="Người khác trong gia đình, họ hàng biết hay không")
axis(2,at=seq(0,.6,.1),labels=paste(100*seq(0,.6,.1),"%",sep=""),las=1)

When I run this, the đ in the main title and the two ơ's and the đ in the legend turn into d and o.

解决方案

You are often safer specifying unicode characters by their hex codes:

plot(1:4,rep(1,4),pch=c("\u0111","\u01B0","\u01A1","\u0103"),cex=4)
