[R] error bars

[S Ellison]

You have likely failed to install the required package or load the right library for the function you are trying to use. 

R 2.13 doesn't have an errbar function natively either, so there must have been such a package present in your R 2.13 installation. I have functions by that name in Hmisc and sfsmisc but I don't know whether either of those the one you were looking for; you'll have to go back to your code to see which library it used to load.
