Dear All,

Greetings. I am a new user of R programming.

I have a large ASCII data file with 14 columns and 45000 rows. I tried to
load the file using read.table(), scan(), etc. functions, but failed to
load the data file properly. Missing values in my data are denoted by
"NaN". I also want to exclude these lines. I don't have a column header but
I would like to include the labels in plotting. All the data is in floats.

Can anyone give me some short examples to open my file?

Look forward for your support,

Thanking you in advance,
