Hi all. how does one send the eval commands to the when running R code
blocks to RSS to the background? currently when i evaluate a long code
block it freezes Emacs until the process is done. here is an example code
block i use:
#+BEGIN_SRC R :session R1 :results output
log.sga.270 <- glm(NSGA ~
IQRfintempmabirth+sinetime+costime+age_centered+age_centered_sq+cig_preg+cig_pre+med_income+p_ospace+gender+prev_400+
diab+hyper+lungd+diab_other+prevpret+as.factor(kess)+as.factor(MRN)+as.factor(edu_group)+as.factor(byob)+parity,data=bd,family=binomial)
summary(log.sga.270)
#+END_SRC
thx so much in advance

I didn't run this, but have trained machine learning models in the
past which run for a while. You should be able to do C-g to un-freeze
the cursor in Emacs, while the code will still be executed in your R
session. Try doing C-c C-c to start that block, C-g, and then C-x b to
switch to the R1 buffer. You should see that the cursor isn't on a
prompt, which means R is busy, yet you're free to move around in your
org buffer and keep writing or doing whatever you want, even though
the R session is tied up.
Best regards,
John
