# [R] dynamic lists (data frames?)

```Hmm my bad,
Thanks for your replies but I think my example was a little to simple
the actual code I'm using is:

f_haardisolve<-function(v_dataset){
#pad data to make length a power of 2

l_cooef<-list() #holder for cooefficents
i_count<-1      #identity counter

while(length(v_dataset)>0){
#seperate odd and even points
v_dataset<-f_splitpoints(v_dataset)

v_dataset<-f_haarpredict(v_dataset)
v_dataset<-f_haaruplift(v_dataset)

str_idx<-paste('c',i_count,sep='')
l_cooef
\$str_idx<-v_dataset[c((length(v_dataset)/2)+1:(length(v_dataset)/2))]
#should be no wrap on the previous line

v_dataset<-v_dataset[c(1:length(v_dataset)/2)]

i_count<-i_count+1
}
l_cooef
}

In this particular case I could probably calculate the number of
iterations and use l_cooef<-names() but more is there a more generic
method for adding another column of data?
