There are many possiblities. Yes, there can be a limit of what R will
diplay to you. E.g. when I load a large data frame and have R print it
to the screen I get :
> foo <- read.table('some-large-table')
> foo
[... lots of row here ...]

[ reached getOption("max.print") -- omitted 4936 rows ]]
but the data is all there:
> dim(foo)
[1] 6721 56
So the first thing you need to do is figure out if R is reading all data
or not. In case you find that you really end up with too few rows, I'd
have a look at the 'quote' option of read.table (assuming that's how you
read the file).
In order to give better advice, we'd need to know what you did and why
you think not all data is there.
