How to set max ppsize in R?
r
Solution
I found a similar problem and that the actual issue was related to expansion of formulas into a model matrix. If you can get the data into that format without using formulas and then use the overload in the svm command (like many other models) that takes an X and y value instead, your probably may go away like mine did.
Problem
I am experiencing an error in R that says: ``` > Error: protect(): protection stack overflow ``` I have learned through googling that I need to increase: ``` > --max-ppsize ``` R-manual:Memory This can only be set when starting R so I write the following in the command prompt: ``` C:\Program Files\RStudio\bin\rstudio.exe --max-ppsize=5000000 ``` The error still occurs. I am running a 1500R x 26000C dataset. How do I solve this problem? Edit: The problem occurs in a standard SVM() function, where I pass a dataset of the size 600R x 26.000C. It does not happen when the dataset is 600R x 12.000C. ``` > model <- svm(TARGET ~ ., data = ds, type = "C-classification", kernel "linear", scale = TRUE, cost = c, cross = k) ```
