R; I would like to combine several matrices from a list together into one matrix

Question

I would like to combine several matrices from a list into a single large matrix. I am sure this is obvious but I am getting me feet wet with R programming. I have tried several attempts with the unlist function but to no avail. Any help would be appreciated. The following is the list:

> list(allele.freq.locus.p)
[[1]]
[[1]]$locus1.allele1
[[1]]$locus1.allele1$`123`
           locus  population allele number heterozygote

7 locus1.allele1 population2    123     10            6 
8 locus1.allele1 population3    123      6            2

I would like to generate a matrix that looks like this:

28 locus3.allele1 population3    176      7            5

are you sure its a matrix. Or is it a list of dataframes? Try `class(allele.freq.locus.p[[1]])` — Mark Heckmann, Jan 08 '14 at 10:30

These look to be data.frames, but does not matter:

do.call("rbind", list.of.data)
