Hello!

I have this error in R:

In svm.default(x, y, scale = scale, ..., na.action = na.action) :
  Variable(s) ‘X.11.’ constant. Cannot scale data.

Of course, I have a column of 25 rows where the values are always 0. Why it
is not possible to have a column with 0?
I need this column because is a feature from a patient. Is there any way to
solve this error?

Thanks in advance!
