減小繪圖的大小

你好，我在 R 中的 knitr 中有這個圖，我想將其傳輸到我的 Latex PDF 文件中，但它太大了，填滿了頁面的 3/4：

compPlot ( mdata$GDP, fitted( cesNewton), xlab = "Real Values",
ylab = "Fitted Values", col="red", main="Newton Method",  
cex.main=1, cex.lab=0.75, cex.axis=0.75)

我怎麼能讓它變小並居中在頁面中間？

\documentclass{article}

\begin{document}


<<>>=

library(micEconCES)

library(readxl)

DATA_FOR_2 <- read_excel("~/Documents/DATA FOR  2.xlsx", 
col_types = c("text", "text", "text", "text", "text", 
"numeric", "numeric","numeric", "numeric", "numeric", 
"numeric", "numeric", "numeric", "numeric", "numeric", 
"numeric", "numeric", "numeric", "numeric", "numeric", 
"numeric"))

mdata <- DATA_FOR_2[-c(46:62), ]

cesKmenta <- cesEst( yName = "GDP", xNames = c( "Capital", "Labour" ), 
data = mdata, method = "Kmenta", vrs = TRUE )

library( "miscTools" )

compPlot ( mdata$GDP, fitted( cesKmenta ), xlab = "Real Values",
ylab = "Fitted Values", col="red", main="Newton Method",  
cex.main=1, cex.lab=0.75, cex.axis=0.75)

\end{document}

抱歉，我不知道如何新增可重現的數據，我只是列出了我匯入的 Excel 工作表

您必須使用 chunk 選項來控制輸出，並閱讀這個重要頁面：https://yihui.name/knitr/options/

這是一個可以回答您問題的 MRE

\documentclass{article}

\begin{document}
\SweaveOpts{concordance=TRUE}
\begin{figure}
\centering
<<minimal, fig=TRUE, height=12>>=
data(mtcars)
plot(mtcars[,1:2])
