[R] Error in geweke.diag function of coda package Hi R users, 

Does anybody knows for the following erro after running 

geweke.diag(MCMC.sampled, frac1=0.1, frac2=0.5) 


Erro em glm.fit(x = X, y = Y, weights = weights, start = start, etastart = 
etastart,  : 
	laÃÂ§o interno 1; nÃÂ£o ÃÂ© possÃÂ­vel corrigir o tamanho do passo 
AlÃÂ©m disso: Warning messages: 
1: algoritmo nÃÂ£o convergiu in: glm.fit(x = X, y = Y, weights = weights, 
start = start, etastart = etastart, 
2: algoritmo nÃÂ£o convergiu in: glm.fit(x = X, y = Y, weights = weights, 
start = start, etastart = etastart, 
3: algoritmo nÃÂ£o convergiu in: glm.fit(x = X, y = Y, weights = weights,

4: algoritmo nÃÂ£o convergiu in: glm.fit(x = X, y = Y, weights = weights,

5: tamanho do passo truncado por causa de divergÃÂªncia 

Thanks for any help.
