problem adding curve/abline
...872*x), from=0, to=22, add=T, lwd=1, col="blue",lty=1) After having to add plot.new() in the front, the line does or not show up, or shows up but wrongly placed. I thought this might be because of the subset, so I wanted to do something like this: modsumm=nls(weight~exp(a+b* size), data=engsAGG2[seizon=="summer"], start=list(a=0,b=0)) which returns: "undefined columns selected" Thanks in advance for the reply.
