Is names(model1$coef) what you're looking for? -----Original Message----- From: Kenneth Cabrera [mailto:krcabrer at epm.net.co] Sent: 29 November 2002 10:36 Cc: R-help at stat.math.ethz.ch Subject: [R] Obtaining the variable names of a glm object Hi, R users! Suppose I make a model like this: model1<-glm(resp~var1+var2+factor1+factor2+var1:factor1+var1:factor1+var2:factor2+var2:factor2,family=poisson) where "resp" is a response variable (poisson distributed) "var1" and "var2" are continuous variables and "factor1" and "factor2" are nominal variables (here I use them as dummy variable) "factor1" has 2 levels (2 and 8) and "factor2" 3 levels ( 1, 6 and 12). Now I want to obtain the labels of the coeficients of the model in 3 separate columns and a 4th column with the corresponding value, like this: variable1 variable2 level value (intercept) X var1 X var2 X factor1 8 X factor2 6 X factor2 12 X var1 factor1 8 X var1 factor2 6 X var1 factor2 12 X var2 factor1 8 X var2 factor2 6 X var2 factor2 12 X If I use: model1$coef, I obtain the name of the coef, but joined. I want them separated.

names(model$coef[1]) use integers in square brackets to adress the position of your lhs-variable, is this what you want?
