Error in plot.new() : the base graphics system is not registered about rcall.jl HOT 7 CLOSED

Hmm, if I insert a rprint("gc()") call in the middle, that seems to fix things. Does this mean it's a memory leak somewhere?

from rcall.jl.

The code runs well on my OS X 10.10.3 with Julia 0.3.7, RCall 0.1.2.

from rcall.jl.

I get the message at random. Not sure how to reproduce it. Your code runs well some time but not another.

Error in plot.new() : the base graphics system is not registered

from rcall.jl.

It is related to the variable baseRegisterIndex in C

unsafe_load(cglobal((:baseRegisterIndex,RCall.libR),Int32))

The normal value of baseRegisterIndex should be >=0. However, due to unknown reason, the value was changed to -1, which lead to the error.

A way to change it to -1 that I know of is

ccall((:Rf_KillAllDevices,RCall.libR), Int32, ())

from rcall.jl.

I think the problem may have been that the finalizer was being called prematurely. Hopefully this works correctly now. Please reopen if there are further problems.

from rcall.jl.

Good catch. It should be the reason. As Rf_endEmbeddedR calls Rf_KillAllDevices which sets baseRegisterIndex to -1.

from rcall.jl.

Yeah, I guess the crazy nature of the bug should have been a clue it was gc related.
