Crashing rfsrc.fast and rfsrc

[RacioBR]

Hi,

I am trying to develop a Random Forest for a strong imbalanced data (99,7% vs 0,3% sucess) with 205.546 observations and 35 variables. I am using Xubuntu (see some Hardware info below) and when I tried to run the following command:

rfsrc.fast(DependentVariable ~ .,dataUsed, ntree = 1000, perf.type = "gmean", do.trace = TRUE, statistics = TRUE)

I received the following output:

"Trees Grown: 1, Time Remaining (sec): 999 Trees Grown: 82, Time Remaining (sec): 34 Trees Grown: 165, Time Remaining (sec): 26 Trees Grown: 242, Time Remaining (sec): 22 Trees Grown: 323, Time Remaining (sec): 19 Trees Grown: 402, Time Remaining (sec): 17 Trees Grown: 483, Time Remaining (sec): 14 Trees Grown: 564, Time Remaining (sec): 12 Trees Grown: 642, Time Remaining (sec): 10 Trees Grown: 723, Time Remaining (sec): 8 Trees Grown: 802, Time Remaining (sec): 6 Trees Grown: 884, Time Remaining (sec): 4 Trees Grown: 966, Time Remaining (sec): 1

RF-SRC: ERROR RF-SRC: Stack imbalance in PROTECT/UNPROTECT: 5 + 1 versus 7
RF-SRC: Please Contact Technical Support.<simpleError in doTryCatch(return(expr), name, parentenv, handler): RF-SRC: The application will now exit.

Error in rfsrc(data = list(RegiaoBrasil = c(1L, 1L, 1L, 1L, 1L, 1L, 1L, : An error has occurred in the grow algorithm. Please turn trace on for further analysis."

Apparently, some problem with C. I used RStudio initially and got mostly the same output using Rscript in Terminal (only adding "Calls: rfsrc.fast -> do.call -> rfsrc Execution halted")

Any clue how to solve this?

Thanks in advance.

Rinaldo.

Remove the option for statistics. Try the following and see if you still get this error:

rfsrc.fast(DependentVariable ~ .,dataUsed, ntree = 1000, perf.type = "gmean")

Worked. Thanks.
