Hello,
 
I have a list with n numerical components of different length (3, 4 or 5
values in each component of the list); I need to export this as a text
file where each component of the list will be a row and where missing
values should fill in the blanks due to the different lengths of the
components of the list.
I think that as a first step I should convert my list to a data frame,
but this is not such a simple task to accomplish: I was thinking of the
following "for" loop:
 
X<-data.frame(1,1,1,1,1);
 
for (i in 1:length(list)) {
 
    X[i,]<-unlist(list[[i]]);
 
}
 
Unfortunately, when the number of elements in the components of the list
are lower than 5 (maximum), I get errors or undesired results. I also
tried with rbind(), but again I couldn't manage to make it accept rows
of different length.
 
Does anybody have any suggestions? Working with lists is very nice, but
I still have to learn how to transfer them to text files for external
use.
 
Thnak you,
