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.

Subject: [R] Help with list
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.
