Re: [R] coping with a warning in if()

Thanks to all who responded. I've learn a lot from your comments. The best solution I can see is to use both 'missing()' and 'match.arg()' in my function. Héctor Hi, I'm sure this one is very easy I am trying to write a function where one of its arguments has two posible (strings)

Thanks to Jim and Greg, Concerning the colors of the arrows, color.scale() function from Jim's solution seems more straigthforward to me. I'm trying now to include a proper legend with color.legend() function. Héctor On 20 Jan 2009 at 22:13, Jim Lemon wrote: Héctor Villalobos wrote: Dear

[R] nls() vs lm() estimates

Hi, I'm trying to understand why the coefficients a and b for the model: W = a*L^b estimated via nls() differs from those obtained for the log transformed model: log(W) = log(a) + b*log(L) estimated via lm(). Also, if I didn't make a mistake, R-squared suggests a better adjustment for the
