R encountering fatal error and quitting the session

Question

[anjalivasudevan98]

Hey everyone,

I am trying to run a multiple-output Random Forest prediction using the randomForestSRC package using the rfsrc() command. I'm trying to run with ntree = 10, using my response variables [ 21 ] using a dataframe of [ 3670x217 ].

Line of code I'm trying to execute:

#training the RF model
rf_model <- rfsrc(response_formula_subset, data = train_data, na.action = "na.omit", ntree = 10)

R keeps showing this message with the symbol of a bomb saying R encountered a fatal error, needs to quite session and asking to restart the session.

I tried using a subset of the data (as you can see in the code, the subset includes only 5 responses). There would be roughly just under 200 predictors.

Really helpful if someone can explain why this is happening!

Thanks in advance!

Looks like a memory related problem. Have you tried with save.memory = TRUE ?

Just tried it, displaying the same error and R crashes
