Error in renderPlot({ : could not find function "renderPlot" #2

I am starting Lab 4 and installed shiny and flexdashboard but am still getting the error

'''{r} Error in renderPlot({ : could not find function "renderPlot" '''

I have omitted more of the plot code, but included the first section below. I'm not sure how to proceed.

library( dplyr )
library( Lahman )
library( pander )
data( Teams )

ave.so <- Teams$SO / Teams$G  # average strike-outs per game each season 
year <- Teams$yearID

Teams$ave.so <- Teams$SO / Teams$G  # add back to data frame so you can subset

```{r}

renderPlot({

plot.new()
plot.window( 
  xlim=c(1900,2025), 
  ylim=c( ave.so.min, ave.so.max ) )
points( year, ave.so, 
        col=adjustcolor("lightgray",alpha=0.75 ), 
        pch=20, cex=1)
points( league.year, league.ave, 
        type="o",lwd=3, 
        col=adjustcolor("dodgerblue4", alpha=0.67),
        cex=.5,pch=19 )
points( 1924, 2.7, 
        col=adjustcolor("black",alpha=0.75 ), 
        pch=21, cex=1.5)
points( 2012, 7.5, 
        col=adjustcolor("black",alpha=0.75 ), 
        pch=21, cex=1.5)

})

For running Shiny, you are not suppose to run code chunks one by one but to run the entire document at once by clicking the "Run Document" option at the top.
