Stargazer output appears below text - rmarkdown to pdf

Question

The Problem

When using rmarkdown in RStudio, my stargazer(glm()) output gets positioned below the text that I would like it to. It gets

Answer 1

Set float = FALSE. From the manual,

float: a logical value that indicates whether the resulting table will be a 
floating table (set off, for instance, by \begin{table} and \end{table}).

In LaTeX, a table environment is a floating environment.

E.g.

stargazer(mtcars_glm, ci=FALSE, no.space = TRUE, report = c("vc*"), float = FALSE)

Answer 2

If you set float = FALSE, you will not have any of the features that come with a floating environment, such as captions (i.e. the title) or labels. Instead, consider setting an unconditional table placement with the float package. As an example, consider the following document (I use \clearpage to start the body on page 2 so we can see the adjoining pages on the screenshot):

---
title: "Untitled"
author: "Me"
header-includes:
   - \usepackage{lipsum}
output: pdf_document
---
\clearpage
\lipsum[1]
```{r setup, echo = FALSE, include = FALSE}
library(stargazer)
mtcars_glm <- glm(formula = vs ~ disp + am + cyl + mpg, family = "binomial", data = mtcars)
```

Table 1 here.
```{r tab1, results = 'asis', echo = FALSE}
stargazer(mtcars_glm, ci=FALSE, no.space = TRUE, report = c("vc*"), 
          header = FALSE, title = "Table 1")
```

\lipsum[2-3]
Table 2 here.
```{r tab2, results = 'asis', echo = FALSE}
stargazer(mtcars_glm, ci=FALSE, no.space = TRUE, report = c("vc*"), 
          header = FALSE, title = "Table 2")
```

\lipsum[4]

which gives

where Table 2 has been bumped to the following page, and the text after Table 2 has been moved up. This is how LaTeX behaves; it does not want to leave too much white space at the bottom of the page. To insist that Table 2 follows a piece of text, you can use the H specifier (which requires the float LaTeX package). Here's the same document, but note the table.placement argument in the tab2 chunk:

---
title: "Untitled"
author: "Me"
header-includes:
   - \usepackage{float}
   - \usepackage{lipsum}
output: pdf_document
---
\clearpage
\lipsum[1]
```{r setup, echo = FALSE, include = FALSE}
library(stargazer)
mtcars_glm <- glm(formula = vs ~ disp + am + cyl + mpg, family = "binomial", data = mtcars)
```

Table 1 here.
```{r tab1, results = 'asis', echo = FALSE}
stargazer(mtcars_glm, ci=FALSE, no.space = TRUE, report = c("vc*"), 
          header = FALSE, title = "Table 1")
```

\lipsum[2-3]
Table 2 here.
```{r tab2, results = 'asis', echo = FALSE}
stargazer(mtcars_glm, ci=FALSE, no.space = TRUE, report = c("vc*"), 
          header = FALSE, title = "Table 2", table.placement = "H")
```

\lipsum[4]

which gives

The table is placed after the text ("Table 2 here"), even at the expense of leaving white space at the bottom of the page. An alternative is \FloatBarrier from the placeins package; see https://tex.stackexchange.com/questions/19766/how-to-control-the-position-of-floating-images.

In general, you should leave float (i.e. tables and figures) placements to LaTeX. See https://tex.stackexchange.com/questions/39017/how-to-influence-the-position-of-float-environments-like-figure-and-table-in-lat for an extensive discussion.
