Exercise 4
Use pipes to evaluate and summarize the relationship between weight and year for the species "DS". Make sure that you filter for missing values in weight.
The code in sequential form would look like the following:
surveys_DS <- filter(surveys, species_id == "DS", !is.na(weight))
surveys_DS_lm <- lm(weight ~ year, data = surveys_DS)
summary(surveys_DS_lm)
