Hi, I am using R a lot to make plots relating to radioactivity, I am often using expression() to label the plots with nuclide names written with superscripts, e.g. expression(paste(Releases of , { }^{99},Tc, (TBq/year)))-ywtext But, is there any simple way to change the number and name

You implicitly (probably) used na.omit on your dataset, and it added an na.action attribute to the data frame. Try not doing that (e.g. bu using na.action = na.fail and search the archives for the same question about model.tables). Are there any missing values in your dataset? If so, you should

It's a difference in the `libc'. Asking for more precision than the arithmetic has is asking for fairly random results. The differences are as likely to be in the *printing* as in the computations. On Fri, 31 Jan 2003, Bob Gray wrote: Does anyone know precisely what is different about the
