具有不同列类型的xtable

Question

我试图在我的表上使用xtable的各种列类型，包括数字、latex命令和字符串。

示例：

a1 <- paste("\\multirow{2}{*}{", c(1, 2, 3, 4),"}", sep = "")
a2 <- rep(NA, 4)

riffle <- function (a,b) { 
n <- min(length(a), length(b)) 
p1 <- as.vector(rbind(a[1:n], b[1:n])) 
p2 <- c(a[-(1:n)], b[-(1:n)]) 
c(p1, p2) 
}

 a <- riffle(a1, a2)
 b <- rnorm(8, 0, 1)
 c <- rep(c("a", "b"), 2)
 d <- rexp(8, 2)*10
 tab <- cbind(a, b, c, d)
 print(xtable(tab), include.rownames = FALSE)

然而，产出并不令人满意：

 \begin{table}[ht]
    \centering
    \begin{tabular}{llll}
      \hline
    a & b & c & d \\ 
      \hline
       $\backslash$multirow\{2\}\{*\}\{1\} & 0.567183110307595 & a & 17.4277735359976 \\ 
       & -1.45110043335658 & b & 5.78849371967322 \\ 
      $\backslash$multirow\{2\}\{*\}\{2\} & 1.19040399046713 & a & 0.692481031836454 \\ 
       & 1.08180700975955 & b & 8.30343133216384 \\ 
      $\backslash$multirow\{2\}\{*\}\{3\} & 0.770520985309568 & a & 4.95384422575539 \\ 
       & 0.318790423633696 & b & 1.55130311148241 \\ 
      $\backslash$multirow\{2\}\{*\}\{4\} & 0.672622845121449 & a & 6.01311508645727 \\ 
       & 1.09581061308637 & b & 2.99998417729512 \\ 
       \hline
    \end{tabular}
    \end{table}

我想得到这样的东西：

\begin{table}[ht]
\centering
\begin{tabular}{llll}
  \hline
a & b & c & d \\ 
  \hline
   \multirow{2}{*}{1} & 0.567  & a & 17 \\ 
                      & -1.451 & b & 6 \\ 
  \multirow{2}{*}{2}  & 1.190  & a & 1 \\ 
                      & 1.082  & b & 8 \\ 
  \multirow{2}{*}{3}  & 0.771  & a & 5 \\ 
                      & 0.319  & b & 2 \\ 
  \multirow{2}{*}{4}  & 0.673  & a & 6 \\ 
                      & 1.096  & b & 3 \\ 
   \hline
\end{tabular}
\end{table}

包括数值列的不同舍入(通常在打印时使用digits命令是可行的，但不适用于我的表)

Answer 1

解决方案是在print()函数中为xtable对象使用xtable。

tab <- data.frame(a, b, c, d)
print(xtable(tab), include.rownames = FALSE, sanitize.text.function = force)

输出：

\begin{table}[ht]
\centering
\begin{tabular}{lrlr}
  \hline
  a & b & c & d \\ 
  \hline
  \multirow{2}{*}{1} &  1.26 & a & 2.43 \\ 
   & -0.42 & b & 3.60 \\ 
  \multirow{2}{*}{2} & -0.14 & a & 6.27 \\ 
   & -0.12 & b & 1.68 \\ 
  \multirow{2}{*}{3} &  0.70 & a & 2.15 \\ 
   & -1.05 & b & 0.62 \\ 
  \multirow{2}{*}{4} &  2.29 & a & 0.84 \\ 
   & -0.21 & b & 3.36 \\ 
   \hline
\end{tabular}
\end{table}
