在Rmarkdown中显示来自新窗口图的图

Question

I am new to rmarkdown and I would like to show a plot which is normally produced in a new window. This plot is called from a function that displays it in a new window using plot.new() and dev.new() and also adds several plots in that window. How can I return this to the report?

the following does not return the plots...

```{r  fig.keep='all', fig.width=10, fig.height=5}

Draw_matrix_plots(data)

```

and the function skeleton I am calling which draws four plots in a new window:

Draw_matrix_plots <- function(data){
  plot.new()
  dev.new(width=7, height=8)
  layout(matrix(c(1,2,3,4), 2, 2, byrow = TRUE),heights=c(3,3))
  hist(data$A)
  hist(data$B)
  hist(data$C)
  hist(data$D)
}

Thanks

I think you just don't need the dev.new(), the following code produce

 ---
title: "Test"
ouptut: pdf_document
---

# R code

```{r  fig.keep='all', fig.width=10, fig.height=5}
Draw_matrix_plots <- function(){
  layout(matrix(c(1,2,3,4), 2, 2, byrow = TRUE),heights=c(3,3))
  hist(rnorm(100))
  hist(rnorm(100))
  hist(rnorm(100))
  hist(rnorm(100))
}
Draw_matrix_plots()

```

You can check that the figures are created in the /figure folder. I have the same with html_document as an output. Does that help ?
