Hello,
First of all, I really like Rccp and would like to thank you all for your work.
I try to debug an cpp file, which I source from R, using the lldb debuger.
sourceCpp("source.cpp")
Everything is woking fine, but I dont get how can I show the content of
specific datatypes. Like NumericVector or CharackterVector.
E.g.:
(lldb) fr v myvec gives me:
(Rcpp::CharacterVector) myvec= {
Rcpp::PreserveStorage<Rcpp::Vector<4> > = (data = 0x000055555899e970)
cache = {
p = 0x00007fffffffc070
}
}
How it is possible to get the values of the vector in lldb?
I think, that the struct CharacterVector only stores the Memory address of the
data.
I have the same problem with NumericVectors, which are stored as double.
If I tried to access them (format as double, 2072 bytes) but I didn´t get the
expected values:
(lldb) memory read –format f 0x000055555899e970
(llldb) memory read -s2072 -fu -c2072 0x000055555899e970 --force
Maybe I have a mistake. I would be very happy if someone could help me.
I've already posted this question on Stackoverflow, but have not received an
answer.

Bests,
