My apologies! I made this much to complicated and allowed myself to become
confused with the straightforward advice given. I tried running the lines
Mr. Barradas suggested after receiving the output for as.matrix() and I
understand now. Thank you all again for your patience.

You continue to labor under false conceptions, starting with your
subject line indicating that you should be able to *see* your huge data
set in the R console.
Take a pause, have a coffee or tea and re-read the helpful advice
various people have tried to offer before continuing this thread.

Spencer, what prints into your console is not the point. As others have
said, the best way to find it if an R object is the type matrix is
is.matrix() . That will return TRUE or FALSE.

So even though a number of rows were omitted during the ‘print in’ or
visualization of the dataset into my console, the data frame is now set as
a matrix? I believe so, per Mr. Barradas’s last email. Sorry for the
confusion, I was expecting the whole dataset to load into my console and
was concern
Why do you need it to be a matrix? A data.frame is like a matrix, but
allows columns of mixed types.
as.matrix() will coerce your data frame to a matrix if you really need this.

The obvious question is "what do you mean, FORMATTED AS a matrix?"
Once you have read an object into R, you have no information about how it
was formatted.
Another question is "what do you mean, MATRIX"?
Do you mean the kind of R object specifically recognised by is.matrix,
or do you mean "rectangu

Consider ?is.matrix ?

Hello,
Look at the output of these two commands:
1) str()
str(matrix(0, nrow = 20530, ncol =173))
num [1:20530, 1:173] 0 0 0 0 0 0 0 0 0 0 ...
The important part is
num [1:20530, 1:173]
This says it's a numeric vector with dimensions 20530 and 173, it's a matrix
2) str()
str(as.data.fram
Using str(GBM.txt) produced the same output as last time, which lists the
number of objects acting on a particular number of variables for the said
dataset and a few rows read from the original file.
The result of class(GBM.txt) generates the following..
> class(GBM.txt)
[1] "data.frame"
Is this
Why did you not do as Kevin suggested??
Or, more simply, ?is.matrix
which could be found in ?matrix.
*Please* consult R's docs before posting such queries.

Hello,
I am trying to reload some data into R in order to check to see if it is
formatted as a matrix. I used the command options(max.print = 1000) to
account for the 20,000 some rows omitted previously when just using the
basic version of this function. After entering this command, the data
