Dear R users I have a problem with the selection of the variables from a gamma model with log link function:  

step.glm.gam1.infroma<- step(glm.gam1.infroma, direction = "backward", k=2)  

Errore in glm.fit(x[, jj, drop = FALSE], y, wt, offset = object$offset, :   ciclo intero 1; impossibile correggere la ampiezza del passo  Inoltre: Warning message:
ampiezza del passo ridotta a causa della divergenza  

Could someone help me???
Thanks
Silvia
