[R] Storing p-values from a glm

[Arne.Muller@aventis.com]

Hi,

for example one could do it this way:

v <- summary(fit)$coefficients[,4]

the coefficient attribute is a matrix, and with the "4" you refere to the
pvalue (at least in lm - don't know if summary(glm) produces sligthely
different output).

to skip the intercept (1st row): v <- summary(glmfit)$coefficients[-1,4]

	hope this helps,

	Arne
