Hm. That highly depends on the functions you are going to use.

It is one thing to import a data.frame, but another one to do some
calculations on the data. The memory consumption highly depends on the
functions, you are using (creating copies of (parts of) the data, ...).

You won't need 1GB to calculate the mean of 10000 observations for
example. ;-)
