More precisely:
I build a set of vector and a dictionary with string as keys and those
vectors as values. I build an R dataframe object from this dictionary and
run a series of regression using this dataframe. I do this repeatedly and
some variable names are shared between dataframes, someting like
-create dataframe with d=r.as_data_frame(dict(x1=...,x2=..,x3=,x4=..,x5...)
call r.lm('x1~x2+x3',d) and a whole lot of
other
-create new dataframe d==r.as_data_frame(dict(x3=..,....)) where
some of the variable names were in the previous dataframe
i do not really understand either why this occurs randomly. I suspect a race
condition between the garbage collector and the computing process ( do you
know how the R gc is triggered?). Most crashes seem to occur during the
construction of the dataframe.
I will try to get a reproducible scenario which triggers the crash.
Thanks,
Laurent
