[R] Help with list

[arun]

Hi,
May be this help:
Please dput() the example dataset:
Caso<- structure(list(`9` = structure(c(2, 10), .Names = c("0", "1")), 
    `13` = structure(c(2, 4), .Names = c("0", "2"))), .Names = c("9", 
"13"))


nm<-unique(unlist(lapply(Caso,names)))
 vec1<- numeric(length(nm))
names(vec1)<- nm
 do.call(rbind,lapply(Caso,function(x){ indx<- names(vec1)%in% names(x); vec1[indx]<-x;vec1 }))
 #  0  1 2
#9  2 10 0
#13 2  0 4
A.K.

I have a list that gives me the number of occurrences of numbers 1, 2, 3 and
4.


Sometimes a single in a casa just appears 0 and 1, in others only 2, and every
combination you can think of.


Eg


> Caso [1:2]
$ `9`


0 1
2 10


$ `13`


0 2
2 4


Can I turn it into a matrix consisting of 4 columns in which I put the
number of occurrences of the previous numbers, and for cases where it does
not appear any of those values put 0?


Regards,


Sebastian.
