Write several statements into an anonymous function in R

Question

I want to include a plot into some MS Word document using the reporteRs library.

Here is how I include my plot :

doc = addPlot(doc, 
  fun = function() plot(
    km.as.one,
    mark.time=TRUE,
    conf.int=FALSE,
    cex=1,
    col="blue",
    xlab = "Délai en années", ylab = "Pourcentage",
    lty=1:3,
  ),
  vector.graphic = TRUE, width = 5, height = 4,
  par.properties = parProperties(text.align = "center")
)

My problem is that I would like to add some error bars, customize the axis and maybe add the title, by adding something like following :

axis(1, at = seq(0, 36, by = 6))
with (data=summary.km.as.one, expr=errbar(time, surv, upper, lower, add=TRUE, pch=0.5, cap=0.02))

I have to write this outside of the plot statement, but I couldn't find how to write it in the anonymous function.

Is it even possible to write several statements in an anonymous function ?

If yes, what is the right way, and if not, is there any workaround ?

Just add braces { } and you can add multiple lines:

doc = addPlot(doc, 
  fun = function() { 
    # line 1
    # line 2
    # etc...
  },
  vector.graphic = TRUE, width = 5, height = 4,
  par.properties = parProperties(text.align = "center")
)
