[R-sig-ME] lmer maxiter not working?

[Jeff Evans]

Addendum:
	I have tried this now on XP 32 bit (R 2.8.0) and Ubuntu 64 bit
(2.8.1) with the same errors. 

Thanks again,

I have been trying to change the number of iterations allowed by lmer in
lme4 but it always runs for exactly 300 iterations.


mp1 <- lmer(Siliques ~ State * Year +
AdultsJuneD + RosOctD + SumSrv + WinSrv +
soilsPC1 + soilsPC2 + 
WinClimPC1 + WinClimPC2 + WinClimPC2_2 +
(RosOctD*Year | Site) + (1 | ID),
data=dat.gm,
family="poisson",
verbose=TRUE,
control = list(maxIter = 100))

299:     3796.3537: 0.669478 0.895477 5.18862e-10 0.612108 
300:     3796.3537: 0.669478 0.895478  0.00000 0.612108 ......
Warning message:
In mer_finalize(ans) : iteration limit reached without convergence (9)

changing to:
...control = list(maxIter = 10000))

still only runs for 300 iterations with same warning

Any thoughts?

particulars:
?lme4? version 0.999375-28
R version 2.8.1 (2008-12-22)
Vista Ultimate 64 Bit sp1

Thanks,
Jeff
