[R] Function try and Results of a program

[Evgenia]

Hello, users.

Dear users,

*******I have a function f to simulate data from a model (example below used
only to show my problems)

f<-function(n,mean1){
a<-matrix(rnorm(n, mean1 , sd = 1),ncol=5)
b<-matrix(runif(n),ncol=5)
data<-rbind(a,b)
out<-data
out}

*********I want to simulate 1000 datasets (here only 5) so I use
S<-list()

for (i in 1:5){
S[[i]]<-f(n=10,mean1=0)}

******I have a very complicated function  for estimation of a model which I
want to apply to Each one of the above simulated datasets

fun<-function(data){data<-as.matrix(data)
sink(' Example.txt',append=TRUE)
          cat("\n***********************\nEstimation
\n********************\nDataset Sim : ",
            i )
d<-data%*%t(data)
s<-solve(d)
print(s)
out<-list (s,d)
out
}
results<-list()
for(i in 1:5){
     tmp <- try(fun(data=S[[i]]))
     results[[i]] <- ifelse(is(tmp,"try-error"),NA,tmp)
}

####My problem is that results have only the 1st element of the result lists
of fun (i.e. only ####although tmp gives me both s and d. 

Thanks 

Evgenia
