Hi hepppy -
and welcome to the RStudio community!
It appears that you have two variables (Income.. and Fast.Food) that are either character or factor variables, Age is numeric, and Region is likely also a factor variable.
summary() will only give means or medians for numeric variables.
You can find out their variable types by using
str(Research) #for the whole dataset
#or
class(Research$Fast.Food)
You can convert Income.. and Fast.Food to numeric variables
with the as.numeric() function,
as in
Research %>%
mutate(fast_food = as.numeric(Fast.Food))
and then you can run
summary(Research)
