我想自定义xtable
以导出到LaTeX。我知道这里有一些问题xtable
,但我找不到我正在寻找的具体内容。
以下是我的表格的示例:
my.table <- data.frame(Specifiers=c("","Spec1", "Spec2", "Spec3"),
Values1 = c("N=10", 1.03, 1.71, 2.25),
Values2 = c("N=20", 1.32, 1.79, 2.43))
colnames(my.table)[1] <- ""
创造了:
Values1 Values2
1 N=10 N=20
2 Spec1 1.03 1.32
3 Spec2 1.71 1.79
4 Spec3 2.25 2.43
实际上,此表是从。data.frame
{。}}导入的.csv文件中导入的my.table <- read.delim("filename.csv", sep=",", header=TRUE)
现在我用xtable
创建一个LaTeX表:
latex.tab <- xtable(my.table, caption=c("Stats"))
print(latex.tab, file="Summarystats.tex",
floating.environment='sidewaystable',
include.rownames=FALSE,
booktabs=TRUE,
latex.environment=NULL)
以下是生成的LaTeX代码:
\begin{sidewaystable}[ht]
\begin{tabular}{lllllll}
\toprule
& Values1 & Values2 \\
\midrule
N=10 & N=20 \\
Spec1 & 1.03 & 1.32 \\
Spec2 & 1.71 & 1.79 \\
Spec3 & 2.25 & 2.43 \\
\bottomrule
\end{tabular}
\end{sidewaystable}
好的,现在这就是我要改变的地方:
1)在第二行之后而不是在第一行之后插入\midrule
。
2)通过在\rowcolors{2}{gray!25}{white}
(或普通sidewaystable
)环境中插入table
来替换此表行的颜色。
3)将柱名旋转45°
4)在我想要使表格居中的情况下,插入\centering
而不是center
- 环境。
关于如何实现这一目标的任何想法?

你需要一些预处理,额外的参数传递给print.xtable
和一些后期处理:
my.table <- data.frame(Specifiers=c("","Spec1", "Spec2", "Spec3"),
Values1 = c("N=10", 1.03, 1.71, 2.25),
Values2 = c("N=20", 1.32, 1.79, 2.43))
colnames(my.table)[1] <- ""
# Pre-processing: rotates column names by 45 degrees
head = apply(as.array(names(my.table)), 1, function(x) paste("\\rotatebox{45}{", x, "}"))
head = paste(head, c(rep("&", length(head)-1), "\\\\\n"), collapse="")
latex.tab <- xtable(my.table, caption=c("Stats"))
ltable = print(latex.tab, file="", # File is empty, post-processing needed
floating.environment='sidewaystable',
include.rownames=FALSE,
include.colnames=FALSE, # No colnames
booktabs=TRUE,
latex.environment="center", # Or NULL
# Adds some extra-text after the rows specified in pos.
# Adds new \midrule and comments old one.
# Adds pre-processed names of columns
add.to.row=list(pos=as.list(c(0, 0, 1)), command=as.vector(c(head, "%", "\\midrule\n"))))
# Post-processing: replaces \begin{center} with \centering
ltable = sub("\\begin{center}\n", "\\centering\n", ltable, fixed=TRUE)
ltable = sub("\\end{center}\n", "\n", ltable, fixed=TRUE)
# Post-processing: adds alternating colours
ltable = sub("\\begin{tabular}",
"\\rowcolors{2}{gray!25}{white}\n\\begin{tabular}",
ltable, fixed=TRUE)
# Writes output to the file
cat(ltable, file="Summarystats.tex")
如果您需要其他标签环境而不是tabular
1)添加新变量:
TABULAR = "tabular"
2)将它的值传递给print.xtable
,如下所示:
...
tabular.environment=TABULAR,
...
3)更改交替颜色的后处理:
ltable = sub(sprintf("\\begin{%s}", TABULAR),
sprintf("\\rowcolors{2}{gray!25}{white}\n\\begin{%s}", TABULAR),
ltable, fixed=TRUE)
结果:
