在一个旧的.Rnw
文件中,我正在使用RODBC
包读取Excel工作表并显示包含复选标记的乳胶表。
最近,我尝试更改用于读取excel文件的方式,并使用XLConnect
包而不是RODBC
包,但是遇到了一个问题。我无法使对勾符号正确显示。请注意,我传递给xtable进行打印的对象与上一个对象相同,但是结果不一样!
在这里使用我使用的the excel file。
这是有效的.Rnw
。 (我知道代码绝不是最佳)。文件编码为UTF-8,我使用knitr
和XeLaTeX

那是我编译时得到的(这是预期的结果)
这是我面临问题的.Rnw。你能告诉我我需要改变什么吗?

编辑
在下面的代码片段对中,我尝试最小化示例,而忽略了一些无关的部分。再次,第一个是行得通的。同时,我注意到无论在gsub
中使用什么字符串作为替换(在第二个示例中),结果始终相同!

答案 0 :(得分:2)
问题是您的gsub
行的格式。
替换:
dfr <- apply(df,2,function(x) gsub("√","\\\\Checkmark",x)) # √ <U+221A>
使用
dfr <- apply(dfr,2,function(x) gsub("\u221A","\\\\Checkmark",x)) # √ <U+221A>

我在Windows 10以及RStudio和R3.5.1上使用knitr和XeLatex进行排版测试。
.rnw文件在编译时会创建一个中间.tex文件作为输出,然后将其转换为pdf。您必须将正确格式的代码\u221A"
传递给pdf格式应用程序。
