...bian is 100*100. In the original package LSODA it is possible to specify that the jacobian is banded, which makes its inversion very efficient. However, this feature seems to have been removed in the R version. Is there a way to overcome this limitation? Thanks dr.

...uot;mar")) as far as I can see, this only sets (in R-source-code par.c) the variable defaultPlot equal to TRUE. This seems to work, as now par("plt") is calculated when changing the layout. I wonder if this is a good way to do this - does it have other side-effects? Thanks, Karline Soetaert [[alternative HTML version deleted]]

...functions of other packages like nls.lm from minpack.lm and even nlm in base, while some other functions worked as expected. See example below. The symptom is that super assignments (<<-) of unmodified variables lead to "references" instead of copies.

All- I am interested in estimating a parameter that is the starting value for an ODE model. That is, in the typical combined fitting procedure using nls and lsoda (alternatively rk4), I first defined the ODE model: minmod <- function(t, y, parms) { G <- y[1] X <- y[2] with(as.list(parms),{ I_t <- approx(time, I.input, t)$y dG <- -1*(p1 + X)*G +p1*G_b dX <-

Vince, When that happens, one possible reason is that your DAE is of index > 1, which cannot be solved by daspk. The solver radau, also from deSolve can handle DAEs up to index 3, but you need to rewrite the problem in the form M*y' = f(x,y), where M is a mass matrix. If you do that for your problem, and solve it with radau, then radau complains that the "matrix is repeatedly
