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))
