You seemed to have re-written over the "b" object in your code.
This might work for you.
library(MASS)
for (i in 58:1){
for(j in 58:i){
str.temp <- paste("y1 ~ x", i, "* x", j, sep = "")
univar <- glm.nb(as.formula(str.temp), data=df)
b <- summary(univar)$coeffients[4, 4]
if(b < 0.6){
cat(i, j, b, "\n")
}
}
}
By the way, you should post using plain text (not html).
