glm warning message

[Mike Trianni <mstdfw@yahoo.com>]

I have the following data frame, XX;

 NNN   OOO
 1  11   0.0
 2  11   0.0
 3  11   0.0
 4  12   0.0
 5  12   0.4
 6  13   0.5
 7  13   0.6
 8  13   0.7
 9  13   0.8
10  14  0.9
11  14  1.0
12  14  1.0
13  14  1.0
14  14  1.0

When I perform the following glm;

 

glm(OOO~NNN, family=binomial, data="">

 

in S-plus 6.2 there is no 'Warning message', but in S-plus 7.0 I get the following 'Warning message';

 

Warning messages:
  non-integer number of successes in a binomial glm in: glm.fitter(x = X, y = Y, w = w, start = start, offset = offset, family = family, maxit = control$maxit, epsilon =
 control$epsilon, trace = control$trace, null.dev = T)

Why no Warning meesage in 6.2?

 

Thanks for any insight
