Re: [R] please help me

You need better starting values: f - function(x) { c0 - x[1]; ce - x[2]; ae - x[3] sum((v - c0+(ce*(1-exp((-u)/ae^2) } g - 4^(0:8) g - c(-g, g) g - expand.grid(c0 = g, ce = g, ae = g) start - g[which.min(apply(g, 1, f)), ] nls(v ~ c0+(ce*(1-exp((-u)/ae))), data = data1, start = start) On
