Trying recipes::step_ica() with several k columns I did anything I can...
Rscript --vanilla --max-ppsize=500000
...etc.
Error in fastICA::fastICA(n.comp = 5, X = as.matrix(training[, col_names]), :
'Calloc' could not allocate memory (283147929 of 8 bytes)
Is this the ultimate limit of my system?
Is there nothing more I can do, except reducing the cols,
or renting a new server?
