用ggnet避免R输出泄漏到LaTeX中

Question

请考虑以下我通过knitr编译成。tex文档的MWE

documentclass{article}

begin{document}
<<echo=FALSE, message=FALSE, warning=FALSE>>=
library(igraph)
library(GGally)
library(network)
library(sna)
# Set up data
set.seed(123)
g <- barabasi.game(1000)
# Plot data
ggnet(g, weight.method = "indegree")
@

end{document}

插入

begin{verbatim}
## 1000 nodes, weighted by indegree 
## 
##    id indegree outdegree freeman
## 4   4       47         1      48
## 12 12       37         1      38
## 3   3       34         1      35
## 13 13       32         1      33
## 1   1       23         0      23
## 11 11       19         1      20
end{verbatim}

in my .tex.

我怎么能控制它呢?

试试results = 'hide':

documentclass{article}

begin{document}
<<echo=FALSE, message=FALSE, warning=FALSE, results = 'hide'>>=
library(igraph)
library(GGally)
library(network)
library(sna)
# Set up data
set.seed(123)
g <- barabasi.game(1000)
# Plot data
ggnet(g, weight.method = "indegree")
@

end{document}
