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

Z
