I tried reading in your text file with the read.table statement
you provided. Everything worked fine for me - str() shows that
all values are integers, and functions such as summary()
work as anticipated.
You don't tell us *what* you are trying to do. One possible source
of error is that read.table() creates a dataframe - a list, not a matrix.
You can convert dat1
dat1 <- as.matrix(dat1)
and that might work better for your (unspecified) purposes.
If that doesn't help, providing a *working* example of what you
are doing will get you the most effective answers.
