Subject: Cannot rescale a constant/zero column error.
I am trying to run the R Script below, I have actually simplified it to just
this part that is causing issues. When I run this script I continue to get
an error that says "cannot rescale a constant/zero column to a unit
variance". I cannot figure out what is going on here. I have stripped down
my data file so it is more manageable so I can try to figure this out.
The data.txt file that is being read looks like this:
I have made this file very basic on purpose to see if I could get this to
work, but it is not working. Of course once I get this to actually work I
will expand the data file to match the data I am actually using.
If I change the attribute in the prcomp function to scale=FALSE of course I
can run my script. But if it is scaling...which is causing the issues, it
errors.
Any help would be GREATLY appreciated.
