Dear R Community,
I have encountered a problem while using the R function glm.nb.
The code that produce the error was following two lines:
group=c(1,1,1,1,0,0,0,0)
fit=glm.nb(y~group)
While the y contains 8 sets of number like:
gene275 0 1 0 0 1 5 1 0
Error message:
Error in while ((it <- it + 1) < limit && abs(del) > eps) { :
missing value where TRUE/FALSE needed
Calls: glm.nb -> as.vector -> theta.ml
In addition: There were 50 or more warnings (use warnings() to see the
first 50)
Execution halted
Information of my system:

Does anyone happen to have some hit on how to solve this?
Appreciate for any response.
Thanks in advance,
