[R] converting a list to a data.frame

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:  


for (i in 1:length(list)) {  



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,
