为什么R函数print.xtableFtable忽略我的选项? [英] Why does R function print.xtableFtable ignore my options?

问题描述

我有以下代码，print.xtableFtable忽略了乳胶的其他选项.

I am having the following code and print.xtableFtable ignores the additional options for latex.

##### Contingency tables - 34Y
library(xtable)
B <- ftable(prereg34Y_sub$employmentStatus34Y, prereg34Y_sub$ethnicity34Y, dnn=c("Unemployed", "NonBritish"))
sink("CTFemaleNonBrit34Y.tex", type="output")
print.xtableFtable(xtableFtable(B, method = "compact"), table.placement = "h!")
sink()

输出为:

% latex table generated in R 3.3.1 by xtable 1.8-2 package
% Sat Oct 22 18:08:35 2016
\begin{table}[ht]
\centering
\begin{tabular}{l |rr}
\hline
Unemployed $\vert$ NonBritish & \multicolumn{1}{l}{    0} & \multicolumn{1}{l}{    1} \\ 
\hline
0                              & 2065 &   68 \\ 
1                              &   31 &    2 \\ 
\hline
\end{tabular}
\end{table}

表的位置是ht而不是h!.有人知道为什么吗?

The position of the table is ht instead of h!. Does anyone have an idea why?

推荐答案

table.placement参数似乎没有从print.xtableFtable传递到print.xtable，但是您可以设置可选的全局options(xtable.table.placement = "h!")在运行print(xtableFtable(B))

It doesn't seem that the table.placement argument gets passed along from print.xtableFtable to print.xtable, but you can set the optionally globally options(xtable.table.placement = "h!") before running print(xtableFtable(B))

示例

library(xtable)

# table.placement doesnt seem to work
B <- ftable(mtcars$am, mtcars$cyl, dnn=c("Unemployed", "NonBritish"))
print(xtableFtable(B), table.placement = "h!")     
# % latex table generated in R 3.3.1 by xtable 1.8-2 package
# % Sat Oct 22 18:00:52 2016
# \begin{table}[ht]
# ---
# ---

# But works for other data types
B2 <- table(mtcars$am, mtcars$cyl, dnn=c("Unemployed", "NonBritish"))
print(xtable(B2), table.placement = "h!")
# % latex table generated in R 3.3.1 by xtable 1.8-2 package
# % Sat Oct 22 18:00:52 2016
# \begin{table}[h!]
# ---
# ---  

因此要全局设置选项

options(xtable.table.placement = "h!")
print(xtableFtable(B))
# % latex table generated in R 3.3.1 by xtable 1.8-2 package
# % Sat Oct 22 18:00:52 2016
# \begin{table}[h!]
# ---
# ---
