Adjust the distance between code and figure output in knitr

I'm using knitr to write some slides about R graphics. I have the following code in my .rnw file:

\begin{frame}[fragile]

\frametitle{A Região Gráfica}

<<RegiaoGrafica01>>=
plot(0:10, 0:10)
@

\end{frame}

The output I have is

slide 02

However, I think the plot is too distant from my code. I'd like to put the plot higher on the slide, without using something like

\vspace{-10mm}

between two chunks of code (one of them with eval=FALSE and the other with echo=FALSE). I searched knitr documentation, but I couldn't find an option that helps me here.

My minimal reproducible example is below:

\documentclass[10pt, compress, usetitleprogressbar]{beamer}

\usetheme{m}

\usepackage{booktabs}
\usepackage[scale=2]{ccicons}
\usepackage{minted}
\usepackage{amssymb}
\usepackage{amsfonts}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{amsthm}
\usepackage[portuges]{babel}
\usepackage{bm}
\usepackage{icomma}
\usepackage[retainorgcmds]{IEEEtrantools}
\usepackage{mathtools}
\usepackage{multirow}
\usepackage{natbib}
\usepackage{shadow}
\usepackage{subfigure}
\usepackage{tikz}
\usetikzlibrary{shapes.arrows}
\usepackage{verbatim}
\usepackage{xcolor}

\usepgfplotslibrary{dateplot}

\usemintedstyle{trac}

I couldn't make the figure closer to my code, but I added the lines

knit_hooks$set(small.mar = function(before, options, envir) {
    if (before) par(mar = c(14, 4, 0, 4)) 
})
opts_chunk$set(fig.path='figure/beamer-',fig.align='center',fig.show='hold',size='footnotesize', small.mar=TRUE)

according to the knitr manual. Hence, my problem was solved, not because the figure is closer to the commands, but because its margins became smaller.
