三种可能的解决方案。一个使用reporttools和xtable,一个使用tidyverse工具和stargazer,第三个使用base-r解决方案。
第一的,
我想建议你看看reporttools有点离开 stargazer,但我认为你应该看看它,
# install.packages("reporttools") #Use this to install it, do this only once
require(reporttools)
vars <- ToothGrowth[,c('len','dose')]
group <- ToothGrowth[,c('supp')]
## display default statistics, only use a subset of observations, grouped analysis
tableContinuous(vars = vars, group = group, prec = 1, cap = "Table of 'len','dose' by 'supp' ", lab = "tab: descr stat")
% latex table generated in R 3.3.3 by xtable 1.8-2 package
\begingroup\footnotesize
\begin{longtable}{llrrrrrrrrrr}
\textbf{Variable} & \textbf{Levels} & $\mathbf{n}$ & \textbf{Min} & $\mathbf{q_1}$ & $\mathbf{\widetilde{x}}$ & $\mathbf{\bar{x}}$ & $\mathbf{q_3}$ & \textbf{Max} & $\mathbf{s}$ & \textbf{IQR} & \textbf{\#NA} \\
\hline
len & OJ & 30 & 8.2 & 15.5 & 22.7 & 20.7 & 25.7 & 30.9 & 6.6 & 10.2 & 0 \\
& VC & 30 & 4.2 & 11.2 & 16.5 & 17.0 & 23.1 & 33.9 & 8.3 & 11.9 & 0 \\
\hline
& all & 60 & 4.2 & 13.1 & 19.2 & 18.8 & 25.3 & 33.9 & 7.6 & 12.2 & 0 \\
\hline
dose & OJ & 30 & 0.5 & 0.5 & 1.0 & 1.2 & 2.0 & 2.0 & 0.6 & 1.5 & 0 \\
& VC & 30 & 0.5 & 0.5 & 1.0 & 1.2 & 2.0 & 2.0 & 0.6 & 1.5 & 0 \\
\hline
& all & 60 & 0.5 & 0.5 & 1.0 & 1.2 & 2.0 & 2.0 & 0.6 & 1.5 & 0 \\
\hline
\hline
\caption{Table of 'len','dose' by 'supp' }
\label{tab: descr stat}
\end{longtable}

在乳胶中你会得到这个很好的结果,
第二,
受此 SO 答案的启发,使用tidyverse工具和stargazer,
# install.packages(c("tidyverse"), dependencies = TRUE)
library(dplyr); library(purrr)
#> ToothGrowth %>% split(. $supp) %>% walk(~ stargazer(., type = "text"))
#> =========================================
#> Statistic N Mean St. Dev. Min Max
#> -----------------------------------------
#> len 30 20.663 6.606 8.200 30.900
#> dose 30 1.167 0.634 0.500 2.000
#> -----------------------------------------
#> =========================================
#> Statistic N Mean St. Dev. Min Max
#> -----------------------------------------
#> len 30 16.963 8.266 4.200 33.900
#> dose 30 1.167 0.634 0.500 2.000
#> -----------------------------------------
#>
第三,
一个专属的base-r
by(ToothGrowth, ToothGrowth$supp, stargazer, type = 'text')
#> =========================================
#> Statistic N Mean St. Dev. Min Max
#> -----------------------------------------
#> len 30 20.663 6.606 8.200 30.900
#> dose 30 1.167 0.634 0.500 2.000
#> -----------------------------------------
#>
#> =========================================
#> Statistic N Mean St. Dev. Min Max
#> -----------------------------------------
#> len 30 16.963 8.266 4.200 33.900
#> dose 30 1.167 0.634 0.500 2.000
#> -----------------------------------------
#> ToothGrowth$supp: OJ
#> [1] ""
#> [2] "========================================="
#> [3] "Statistic N Mean St. Dev. Min Max "
#> [4] "-----------------------------------------"
#> [5] "len 30 20.663 6.606 8.200 30.900"
#> [6] "dose 30 1.167 0.634 0.500 2.000 "
#> [7] "-----------------------------------------"
#> ---------------------------------------------------------------
#> ToothGrowth$supp: VC
#> [1] ""
#> [2] "========================================="
#> [3] "Statistic N Mean St. Dev. Min Max "
#> [4] "-----------------------------------------"
#> [5] "len 30 16.963 8.266 4.200 33.900"
#> [6] "dose 30 1.167 0.634 0.500 2.000 "
#> [7] "-----------------------------------------"
