Hi, I would like to bound the lower limit of my y scale to zero, and let R chose an upper limit. Something like plot(x,ylim=c(0,)) or plot(x,ylim=c(0,na)) but nither of these do the job. I searched the docs, but I can't see a way to do this. Naturally its nothing I can't do 'by hand', I would just like to know if a correct syntax exists.
