I am having trouble reading in a large (92 columns x 73050 rows = 6720600
cells) data file into a data.frame using read.table because of the way
read.table allocates memory.

I can use scan with nmax = 6720600 and the data will fit into memory, but I
would like to create a data.frame from the data.

What is the best way to do this?  Is there something equivalent to nmax in
With best wishes and kind regards I am
