[R-sig-dyn-mod] deSolve warning and error messages

[Ogurtsova, Ekaterina]

Dear Thomas,

Unfortunately,  my R code is quite sophisticated. However, If you insist, I can write down something short and easy (see below). 
But the problem, in the first place, is not that I have warnings. 

For example:

DLSODA-  At current T (=R1), MXSTEP (=I1) steps   
      taken on this call before reaching TOUT     
In above message, I = 
[1] 10
In above message, R = 
[1] 88.8862

And I have an algorithm how handling this situation later in the code.  But I'm annoyed by the messages and just want to suppress them.

---
Here an artificial example just to reproduce a message:

library(deSolve)

lng<-100
times<-seq(1,100, length=lng)
y<-diag(2)

simpleFun<-function(t,y, parms=NULL){
  	p <- array(y,dim=c(2,2))

  	age<-1:101
 	 tab<-cbind(
    		  -seq(0.1,5,length=101)
    		, seq(0.8,0.1, length=101)
    		, seq(0.1,5,length=101)
   		 , -seq(0.8,0.1, length=101)
 	 )
	  i<- max(which(age<=t))

 	 q<-array(tab[i,],dim=c(2,2))
 	 vec<-c(p%*%q)
 	 return(list(vec,NULL))
}

res<-suppressWarnings(
		lsoda(y=diag(2), times=times
     			 , func=simpleFun
    			  , parms=NULL
     			 , maxsteps=10 )
	)

And the output

>DLSODA-  At current T (=R1), MXSTEP (=I1) steps   
>      taken on this call before reaching TOUT     
>In above message, I = 
>[1] 10
>In above message, R = 
>[1] 1.4032
>

Thanks a lot!

Dear Ekaterina,

thanks for your report, can you please give us a minimal reproducible example?
