Please specify your rpy2 version.
I am running your code without segfault with rpy2-2.04 (to be released shortly) and R-2.9.0/Python 2.4.6 R-2.9.0/Python 2.5.4 R-2.9.0/Python 2.6.2 Trying updating your Python version, then your R version. There were reports of people seeing mysterious segfault disappear with version R-2.8 L. https://bitbucket.org/lgautier/rpy2/issue/6/segfault-when-calling-robjectsrtable On Tue, 2009-04-28 at 11:35 -0700, Kylee Kim wrote: > Hi, > > > I am getting segmentation fault error for robjects.r.table() and > trying to understand why this happens. > Here is simplified example. > > > import rpy2.robjects as robjects > r = robjects.r > mylist = ['a', 'a', 'b', 'd', 'b'] > myNumList = [1,2,3,4] > > > print robjects.IntVector(myNumList) > > > > #>>> print robjects.IntVector(myNumList) > #[1] 1 2 3 4 > > > print robjects.StrVector(mylist) > > > #>>> print robjects.StrVector(mylist) > #[1] "a" "a" "b" "d" "b" > > > print r.factor(robjects.StrVector(mylist)) > > > #>>> print r.factor(robjects.StrVector(mylist)) > #[1] a a b d b > #Levels: a b d > > > # Both of the following produce a segmentation fault error. > r.table(robjects.StrVector(mylist)) > r.table(r.factor(robjects.StrVector(mylist))) > > > I want to pass output of r.table into r.barplot. > > r.barplot(r.table(robjects.StrVector(mylist))) > > > > My environments are: > Python 2.4.1 > > R version 2.7.1 (2008-06-23) > > > > Any advise on usage of r.table() and r.barplot() is much appreciated. > > > Thanks in advance, > Kylee > > > p.s. here are some corresponding R outputs. > > mylist = c('a', 'a', 'b', 'd', 'b') > > mylist > [1] "a" "a" "b" "d" "b" > > table(mylist) > mylist > a b d > 2 2 1 > > barplot(table(mylist)) > ------------------------------------------------------------------------------ > Register Now & Save for Velocity, the Web Performance & Operations > Conference from O'Reilly Media.
