Declare a set (list?) of many dataframes or matrices

Hello,

I can't say I understand the question, but if you want a list of empty 
dfs and a list of empty matrices, the following will do.

replicate(10, data.frame())
replicate(10, matrix(NA, nrow = 0, ncol = 0))


Hope this helps,

Hi,

    I would like to read several datasets and would like to create a set
(list? sequence?) of many empty dataframes. How could this be done? How
could I declare a  set (list? sequence?) of many empty matrices?

    Thanks,

Miao
