使xtable适合pdf文件

Question

我正在创建一个使用xtable创建表并放入pdf文件的sweave文档。它工作，但表不适合文档，一些文本丢失。有没有办法在xtable中完全匹配xtable /将xtable完全匹配到pdf文件？

这是我的数据：

dput(x)
structure(list(App = structure(c(3L, 2L, 1L), .Label = c("AppServer", 
"Db", "Web"), class = "factor"), Group = structure(c(2L, 1L, 
1L), .Label = c("Back", "Front"), class = "factor"), Owner = structure(c(1L, 
1L, 1L), .Label = "Infrasructure", class = "factor"), Server = structure(1:3, .Label = c("ServerA", 
"ServerB", "ServerC"), class = "factor"), NumberCPU = c(64L, 
120L, 120L), Description = structure(c(1L, 3L, 2L), .Label = c("Front End server to server web traffic", 
"Hold Web templates to generate dynamic content", "Keeps customer data and login information"
), class = "factor"), Cost = structure(1:3, .Label = c("$200,000 ", 
"$400,000 ", "$500,000 "), class = "factor")), .Names = c("App", 
"Group", "Owner", "Server", "NumberCPU", "Description", "Cost"
), class = "data.frame", row.names = c(NA, -3L))

这是将表放在pdf中的代码：

print(xtable(x, caption=paste("Summary of applications"),table.placement="!h",caption.placement="top", align=c('l', 'p{1.5in}', rep('c',6) )))

我建议查看xtable gallery，有很多有用的示例。基本上，如果您不想通过缩短字符串来调整表格，我会看到两个选项：

1. 使用较小的字体。
2. 使用横向模式。

在这里，我结合使用两者：

\documentclass{article}
\usepackage{rotating}

\begin{document}

<<Data,echo=FALSE>>=
library(xtable)
x <- structure(list(App = structure(c(3L, 2L, 1L), .Label = c("AppServer", 
"Db", "Web"), class = "factor"), Group = structure(c(2L, 1L, 
1L), .Label = c("Back", "Front"), class = "factor"), Owner = structure(c(1L, 
1L, 1L), .Label = "Infrasructure", class = "factor"), Server = structure(1:3, .Label = c("ServerA", 
"ServerB", "ServerC"), class = "factor"), NumberCPU = c(64L, 
120L, 120L), Description = structure(c(1L, 3L, 2L), .Label = c("Front End server to server web traffic", 
"Hold Web templates to generate dynamic content", "Keeps customer data and login information"
), class = "factor"), Cost = structure(1:3, .Label = c("$200,000 ", 
"$400,000 ", "$500,000 "), class = "factor")), .Names = c("App", 
"Group", "Owner", "Server", "NumberCPU", "Description", "Cost"
), class = "data.frame", row.names = c(NA, -3L))
@

<<tab,echo=FALSE,results='asis'>>=
print(xtable(x, caption=paste("Summary of applications"),
             caption.placement="top",
             align=c('l', 'p{1.5in}', rep('c',6))),
             size="footnotesize",
             floating.environment="sidewaystable")
@


\end{document}

请注意，您必须使用LaTex包rotating。这应该给你这样的东西：

另一种解决方案是使用一些降价后端（knitr，markdown或pander包）并使用{自动将表拆分为80个字符（或其他用户指定的宽度） {1}}。 E.g：

pander

结果可以轻松转换为pdf或LaTeX，然后直接从R > library(pander) > res <- structure(list(App = structure(c(3L, 2L, 1L), .Label = c("AppServer", "Db", "Web"), class = "factor"), Group = structure(c(2L, 1L, 1L), .Label = c("Back", "Front"), class = "factor"), Owner = structure(c(1L, 1L, 1L), .Label = "Infrasructure", class = "factor"), Server = structure(1:3, .Label = c("ServerA", "ServerB", "ServerC"), class = "factor"), NumberCPU = c(64L, 120L, 120L), Description = structure(c(1L, 3L, 2L), .Label = c("Front End server to server web traffic", "Hold Web templates to generate dynamic content", "Keeps customer data and login information"), class = "factor"), Cost = structure(1:3, .Label = c("$200,000 ", "$400,000 ", "$500,000 "), class = "factor")), .Names = c("App", "Group", "Owner", "Server", "NumberCPU", "Description", "Cost"), class = "data.frame", row.names = c(NA, -3L)) > pander(res) ---------------------------------------------------- App Group Owner Server NumberCPU --------- ------- ------------- -------- ----------- Web Front Infrasructure ServerA 64 Db Back Infrasructure ServerB 120 AppServer Back Infrasructure ServerC 120 ---------------------------------------------------- Table: Table continues below --------------------------------------- Description Cost ------------------------------ -------- Front End server to server web $200,000 traffic Keeps customer data and login $400,000 information Hold Web templates to generate $500,000 dynamic content --------------------------------------- 或pandoc转换。
