為什么觀星者以乳膠數學模式輸出此表

Question

我有這個data.frame，我正在嘗試使用stargazer轉換為乳膠代碼：

habitats_df <- data.frame(habitat = c("beach", "grassland", "freshwater"), v1 = c(0.000, 0.670, 0.032), v2 = c(0.005, 0.824, 0.012))


 library(stargazer)
stargazer(habitats_df, summary = F)

 % Table created by stargazer v.4.5.3 by Marek Hlavac, Harvard University. E-mail: hlavac at fas.harvard.edu
    % Date and time: Wed, Jan 22, 2014 - 11:11:44
    \begin{table}[!htbp] \centering 
      \caption{} 
      \label{} 
    \begin{tabular}{@{\extracolsep{5pt}} ccc} 
    \\[-1.8ex]\hline 
    \hline \\[-1.8ex] 
    habitat & v1 & v2 \\ 
    \hline \\[-1.8ex] 
    beach & $0$ & $0.005$ \\ 
    grassland & $0.670$ & $0.824$ \\ 
    freshwater & $0.032$ & $0.012$ \\ 
    \hline \\[-1.8ex] 
    \normalsize 
    \end{tabular} 
    \end{table} 

注意stargazer在數學模式下打印表格，因此它將數字括在$中。 如何在乳膠數學模式下從打印​​表中停止觀星者？

Answer 1

將不需要的任何數字列轉換為字符：

habitats_df$v1 <- as.character(habitats_df$v1)
> stargazer(habitats_df, summary = F)

\begin{table}[!htbp] \centering 
  \caption{} 
  \label{} 
\begin{tabular}{@{\extracolsep{5pt}} ccc} 
\\[-1.8ex]\hline 
\hline \\[-1.8ex] 
habitat & v1 & v2 \\ 
\hline \\[-1.8ex] 
beach & 0 & $0.005$ \\ 
grassland & 0.67 & $0.824$ \\ 
freshwater & 0.032 & $0.012$ \\ 
\hline \\[-1.8ex] 
\normalsize 
\end{tabular} 
\end{table} 

至於“為什么”，是因為否則數字的排版不正確。 如果值為負數，則數學模式將使用更長的破折號，並允許LaTeX控制打印的位數。 否則，如您在上面看到的那樣，如果您想控制位數，則必須在R中使用sprintf進行操作。

Hmisc :: latexSN做得很好。

habitats_df$v1 <- latexSN(habitats_df$v1)
habitats_df$v2 <- latexSN(habitats_df$v2)

library(stargazer)
stargazer(habitats_df, summary = F)
