具有各种列类型的 xtable

xtable with various column types

我正在尝试在我的 table 上使用 xtable 和各种列类型,包括数字、乳胶命令和字符串。

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,输出并不令人满意:

 \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}

包括数字列的不同舍入(打印时使用 digits 命令通常可行,但不适用于我的 table)

解决方案是在 print() 函数中为 xtable 对象使用 sanitize.text.function = force

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}
