Put tables and graphs in the right place (Sweave document)

[José Fernando Zea Castro]

Hello.

I've got some problems putting the tables and graphs (generated in R)  in a specific position in my document. I'm using a Sweave file.  The figures and tables appear in other pages and sometimes in different sections, There are a lot of solved questions about that issue for latex documents, but I can't find specific information for knitR.

Thank you in advance

There is nothing special in knitr -- just use the LaTeX tricks you
found to solve the floating problem, which is very common and in some
cases not trivial to solve in LaTeX.

Thank you, but are there some options in the chunks to place in the desired place the figures and tables?, for example those two chunks:

<<tabla1b, echo = FALSE, results = 'asis'>>=

xtable(table1, caption ="titletable1", label = 'MyT1')

@

<<figura1 fig.lp="figura1:", fig.cap = 'Title figure',echo=FALSE >>=

boxplot(y ~ group)

It is hard to define the "desired" place for floating environments in
LaTeX. It is a problem that bothers many people and there are also
many "solutions", as you have realized. The float package is one of
them, corresponding the "H" position. See one example here:

https://github.com/yihui/knitr-examples/blob/master/067-graphics-options.Rnw

fig.pos="H" only works for figures, of course. For tables, it depends
on which R package you use; the position may or may not be supported.
In typesetting, I believe "many tables and figures" almost surely ends
up in a mess due to the restriction of pages:

even exist in theory as long as this restriction is there.
