Hello, I am both new to this forum and to R. Therefore apologies if I am posting a request for help for something overly simple and/or that has already been covered in past posts. I would really appreciate some simple and straightforward help on how to plot a Rickers growth curve with confidence intervals and to determine r and K. My data is in the very simple form of year and population size. I would like to know how to get these curve parameters in graphical form and as numerical outputs. If someone can help me with some really simple script from start to finish I would be so appreciative. Thank so much in advance -- View this message in context: http://r.789695.n4.nabble.com/Plotting-Rickers-curve-in-R-with-confidence-intervals-tp4483757p4483757.html Sent from the R help mailing list archive at Nabble.com.
