[R] foreach returns null first object in the list

[pakoun]

Dear all,

I am sending you a copy of a demo that i am trying to make that work and
embedded in a more complicated structure. The problem is that i want to get
a list of 2 objects (matrices in specific, and thats why i am not specifing
a .combine argument if i am not wrong..), but the first element of the list
is just null. the second one is perfectly fine. Any idea?
Thank you in advance

 library(doMC)
 registerDoMC(2)

Xa<-matrix(1:100,ncol=10)
Sa<-matrix(101:200,ncol=10)
Ta<-matrix(1:100,ncol=10)
   get.Xp <- function(Xa,Sa){
             result <- Xa%*%Sa
             return(result)
   }
   get.Sa.post <- function(Xa,Ta){

             result <- Ta%*%Sa
             return(result)
   }

  func.list <- list(get.Xp,get.Sa.post)   

  post.ls <- foreach(i =1:2) %dopar% {

             fun <- func.list[[i]]
             if(i==1){fun(Xa,Sa)}
             if(i==2){fun(Ta,Sa)}

             }
 
post.ls
