adjust is an argument to logit(), and I'm assuming na.action is an argument to lm(). >> EvacLM <- lm((logit(sharer_prob) ~ sympathy + trust + fear + greed) >> adjust=TRUE) na.action=NULL) EvacLM <- lm(logit(sharer_prob, adjust=TRUE) ~ sympathy + trust + fear + greed, na.action=NULL, data=data) If this is foreign to you, you should probably go read one of the many good intro to R lessons online.
