[R] creating a "report" table from a set of lists

I've been trying to figure out how to accomplish the following...

I've got a list (returned from a function) and I would like to "cbind()" the
lists together to create a "cross tab" report or simply bind them together

the function returns a list that looks like the following:

> all$BM
[1] "BM"
[1] 3
[1] 54.05435
[1] 20
[1] 26
[1] 5.339182


so there are different variable types in the list (meaning I can't use
cbind?) to create a table with more than one column for stringing together
multiple species. I tried to use rbind and got similar results. Tried
unlist, but the values get cast into strings (which would be alright be
simply reporting values, but I would like to maintain the types (for using
digits=xxx arguments). I've used unlist and rbind, then turn the matrix to

> t(rpt)
               BM                  DF
species        "BM"                "DF"
vbar.nobs      "3"                 "33"
vbar.pctse     "8.77458627230236"  "2.67841483098916"
count.nobs     "20"                "20"
count.se       "0.254175654140783" "0.630267278307595"
...blah, blah, blah....
count.pctse    "39.1039467908896"  "8.34791097096152"
combined.pctse "40.0763274125113"  "8.76707041068808"
basal.area     "26"                "302"
expf           "5.33918184530697"  "48.4101260565985"

which is the desired result, but without the quotes

> print.matrix( t(rpt), quote=F )
               BM                DF
species        BM                DF
vbar.nobs      3                 33
vbar.sum       54.0543454534738  584.712753385096
count.nobs     20                20
count.sum      13                151
...blah, blah, blah....
basal.area     26                302
expf           5.33918184530697  48.4101260565985
volume         100               100

but would still like to be able to control the number of digits that are
printed for the doubles....

Am I even close, or is there more engineering I need to do here?
