How can I get captions on my table floats in pdf_document generated by rmarkdown?
Using
output:
pdf_document:
fig_caption: true
and
```{r, fig.cap='a caption'}
myplot
```
Generates a floating figure with myplot and the caption specified.
How do I achieve the same thing with tables generated by xtable?
```{r, results='asis', fig.cap='table caption'}
print(xtable(table), comment = FALSE)
```
I have tried using floating.environment = 'figure' in print.xtable, but to no avail.
回答1:
Or similarly,
```{r results='asis'}
knitr::kable(head(mtcars), format = 'pandoc', caption = 'Title of the table')
```
回答2:
The 'caption' is a parameter to xtable, not to print.xtable
```{r, results='asis'}
print(xtable(table, caption='Captions goes within xtable'), comment = FALSE)
```

If you are using markdown anyway, why not stick to the same (simple and nice) format. Quick example:
> library(pander)
> pander(table(mtcars$am), caption = 'foo')
