R encoutered a Fatal Error. The session was terminated.

[Rafael Lionello]

Dear all,

I am trying the run compareGroups in a data frame with 900 obs and 140 variables.

I want to compare these variables across four groups (Y = 4). Many of this variables are categorical Likert scales, with five levels.

tab <- compareGroups(clu. ~ ., data = base, na.action=na.pass)

However, it is generating the following error: R encoutered a Fatal Error. The session was terminated.

Apparently, it is a memory issue, because when I reduce the pool of variables (eg., selecting just variable with 4 ou less levels), it works. I have tried different strategies, but nothing works. Also, I have been able to run similar data frames in comparegroups in the past. So, the problema could be a recently updating which I conduct in my computer.

Any help is very appreciated.

Best, Rafael.
