Hello,
Can't you simply call svm() with scale = FALSE ?
If the variable is constant, it cannot be scaled to unit variance (and
zero mean).
Hope this helps,

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!
