[R] Fill a matrix with vectors of different lengths

[Serguei Kaniovski]

Hello,

how can I best fill a (fixed) matrix with vectors of varying lengths by 
column, setting the superfluous elements to zero? Here is my code:

v<-(1,1,2,3,4,6)

binc<-function(x){
	l<-sum(x)+1
	y<-c(1,rep(0,l-1))
	for (i in x) y<-y+c(rep(0,i),y)[1:l]
}

mat<-matrix(0, nrow=sum(v)+1, ncol=length(v))
for (i in 1:length(v)) mat[,i]=mat[,i]+binc(v[1:i])

the expression in the for-loop produces an error since mat[,i] and 
binc(v[1:i]) are of unequal lengths, except on the last iteration.

Thanks in advance,
Serguei
