How to keep a table on the same page?

TeX - LaTeX Asked by Anusha on January 7, 2021

I have a report with many summary tables of regression output and converted them into tables using pander in the Rmarkdown document. Even though all tables are less than one page, they sometimes break and continue on two pages, which is hard to read.

I created the .tex file from .Rmd and converted longtabs to booktabs as a way but couldn’t compile the document. Also, since there are so many tables, adding pagebreak or newpage is not an optimal solution either.

Here is a minimal example of the .Rmd file. The code here is to be pasted in a .Rmd file. How can I make the table be on the same page?

                      message = FALSE,
                      warning = FALSE,
                      error = TRUE,
                      fig.cap = " ",
                      number_sections = TRUE)
```
```{r}

```{r}
m5 = lm(log(Volume)~log(Girth)*log(Height)+Girth^2+Girth^3+Girth^4 + Height^2+Height^3+rnorm(31)+rpois(31, 1),data=trees)
pander(m5)
```

I don’t know how to keep all the chunks intact in this code here. Sorry if that causes confusion. It is converting the markdown code to formatting.

I suggest that you use kable or xtable rather than pander. You will get a table formatted using standard LaTeX syntax and lets you invoke all the kable or xtable formatting capabilities. The following simple .Rmd file is adapted from here: Prettier Result Table With broom And knitr. It does the following:

  1. Fit a linear model to the cars data
  2. Tidies the model output
  3. Formats the model output as a LaTeX table.

Specifically regarding your question about not floating the table, the example sets the table float with [H], so that it does not float at all. This is done with the kable_styling function from kableExtra. If you have a longtable, just add that option to kable().

This is the output from knitting the .Rmd file:

enter image description here

This is the Rmd file:

---
title: "TeX.SE"
output: 
   pdf_document:
     keep_tex: true
header-includes:
   - usepackage{caption}
   - usepackage{booktabs}
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
options(tinytex.clean = FALSE)
```

## Fit the model

```{r cars}
lmfit <- lm(mpg ~ wt, mtcars)
lmfit
```

## Cleanup model output and format table

Use texttt{broom}'s texttt{tidy} function to create a data frame of the model output and output that dataframe using texttt{knitr}'s texttt{kable} function: 

```{r output}
library(broom)        # tidyr
library(magrittr)     # %>%

library(knitr)        # kable
library(kableExtra)   # kable_styling
tidy(lmfit) %>% kable(format="latex",booktabs=TRUE,
                      caption="My table caption",digits=2) %>% 
                kable_styling(latex_options = "HOLD_position")
```
raggedright Add texttt{longtable} to texttt{kable} as required. For example: partexttt{kable(longtable=TRUE, format="latex", booktabs=TRUE, caption="My table caption")}

This is the LaTeX code for the table of regression parameters extracted from the .tex file created by compiling the .Rmd file.

begin{table}[H]
caption{label{tab:output}My table caption}
centering
begin{tabular}[t]{lrrrr}
toprule
term & estimate & std.error & statistic & p.value\
midrule
(Intercept) & 37.29 & 1.88 & 19.86 & 0\
wt & -5.34 & 0.56 & -9.56 & 0\
bottomrule
end{tabular}
end{table}

As you can see, it is just regular LaTeX code with the [H] option applied for table placement.

Here is an improved version of your table. I have remove all unnecessary code clutter and added the siunitx package to improve the alignment of the numbers.
