gnls(0 error: invalid variable type
...by adding an additional column.
Here are bits of info from the previous run (Gbht02.gnls):
 > Gbht02.gnls$call
gnls(model = h2 ~ Rht(b0, b1, b2, h1, t1, t2), data = gbht10, 
    params = list(b0 + b1 + b2 ~ Sisp - 1), start = c(strssb0, 
        strssb1, strssb2))
> Gbht02.gnls$coef[1:5]
b0.SispH1 b0.SispH2 b0.SispH3 b0.SispH4 b0.SispH5 
0.9354108 0.8420247 0.8681101 0.8998161 0.7892491 
Any insight and ideas of the error message? I use R2.0.0 on XP. 
TIA,
