Subject: [Rd] R CMD check [nlme|MASS] fails (PR#431)
Message-ID: <200002111158.MAA02762@pubhealth.ku.dk>

Mmmh, seems as if I really should change my options as I seem to keep
sending off empty bug-reports ;-/ Sorry guys.  Here is the content
that should have been in the last e-mail:

`R CMD check nlme' fails on my machine.  The final output in
nlme-Ex.Rout is:

> library(nlme)
> data(Soybean)
> fm1 <- nlme(weight ~ SSlogis(Time, Asym, xmid, scal), data = Soybean,
+             fixed = Asym + xmid + scal ~ 1, start = c(18, 52, 7.5),
+             control = list(nlmStepMax = 1.0))
Error in nlme.formula(weight ~ SSlogis(Time, Asym, xmid, scal), data = Soybean,  : 
	Maximum number of iterations reached without convergence
Execution halted

I presume that `R CMD check MASS' fails for some similar reason.  The
final output in MASS-Ex.Rout is:

> library(nlme)
> fp2 <- deriv(~ 0.5 + 0.5/(1 + exp(-(x-L75)/2)), 
+             "L75", function(x,L75) NULL)
> OMEi.nls <- nlsList(Correct/Trials ~ fp2(Loud, L75) | UIDn,
+    data = OMEi, start=list(L75=45), control = list(maxiter=100))
Error in nls(formula = formula, data = data, start = start, control = control) : 
	maximum number of iterations exceeded

[above message repeated another 10 times]

Error in qr(attr(rhs, "gradient")) : NA/NaN/Inf in foreign function call (arg 1)
Error in nls(formula = formula, data = data, start = start, control = control) : 
	maximum number of iterations exceeded
Error: cons memory (350000 cells) exhausted
       See "help(Memory)" on how to increase the number of cons cells.

[above message repeated about another 45 times or so]

Execution halted
> tmp <- sapply(OMEi.nls, function(X) 
+               {if(is.null(X)) NA else as.vector(coef(X))})
Error in as.list(X) : Object "OMEi.nls" not found
Execution halted

Cheers,
