R cropping the right hand border of a chart

I created a chart using chart_Series but I want to remove the RHS y axis labels by cropping within R, rather than using an external program

library(quantmod)
getSymbols("SPY", from="2013-01-01", to=Sys.Date())


myTheme <- chart_theme()
myTheme$rylab <- FALSE

chart1 <- chart_Series(SPY,theme=myTheme)

add_TA(SMA(SPY[,4],20),on=1)

But how can I crop the chart to remove the right hand border and also the labels on the rhs y axis?

Thanks for your help.

You can set margins using par.

par(mar=c(bottom, left, top, right))

The default is

par(mar=c(5,4,4,2)+.1)

Margins are expressed in lines. See ?par for more information.

EDIT: it seems I misunderstood the question, but the answer still lies in par!

par(bty='c')

Will plot a "C" box (i.e. only top, left and bottom).
Other possible values of bty include:

n : no box (you can add a customized box using the box function)
7 : only top and right
l : only bottom and left
] : no left border
u : no top border

If needed you can also pass bty directly to plot such as:

plot(x, y, bty="n")
