Error: unexpected symbol in:
"body.glm <- glm(Bodyfat ~ Density + Age + Weight + Height + Neck + 
                 Chest + Abdomen + Hip + Thigh + Knee + Ankle + Biceps + Forearm + Wrist)set.seed (3)"

I am getting this when trying to get my GLM. I don't know if its an issue on how the code is written or if its the dataset.

when running str(bf)

'data.frame':   252 obs. of  15 variables:

this is the data frame.

  • Is the set.seed part literally on the same line as the call to glm? – Dason Nov 03 '21 at 19:28
  • Yes, if not it throws out "Error in y - mu : non-numeric argument to binary operator " – Joaquin Gutierrez Nov 03 '21 at 20:30
  • What if you run `body.glm <- glm(Bodyfat ~ Density + Age + Weight + Height + Neck + Chest + Abdomen + Hip + Thigh + Knee + Ankle + Biceps + Forearm + Wrist, data = bf)` and keep the `set.seed()` line on a separate line? – Phil Nov 04 '21 at 01:54
