How to set the "lwd" parameter in plot.xts?

I just want to set the line width of the line I'm plotting to be of a certain value. The rest (gridlines, border around graph) should remain 1.0 of width.

But if I set par(lwd=2) all lines are wider. If I set plot.xts(AAPL,lwd=2), I get an error:

Error in axis(1, at = xycoords$x[ep], labels = names(ep), las = 1, lwd = 1,  : 
  formal argument "lwd" matched by multiple actual arguments

Heres my code:

library(quantmod)
getSymbols("AAPL")
par(lwd=2)
plot.xts(AAPL)

My solution to this to pass type='n' and then call lines:

require(quantmod)
getSymbols('CPIAUCSL',src='FRED')
xts::plot.xts(CPIAUCSL, type='n')
lines(CPIAUCSL, lwd=3, col='darkgoldenrod')

This does not require the xtsExtra package, which makes other changes and is (maybe) not being actively maintained. (At least it doesn't install via the package manager, today, on R 3.1.1.)

Try using xtsExtra from R-Forge. It has lot of enhancement for plotting xts objects. 

install.packages("xtsExtra", repos="http://R-Forge.R-project.org")

You can use 

library(xtsExtra)

getSymbols("AAPL")

plot.xts(AAPL[,4], lwd = 2)

That will give you
