Type of vector - str and class do not match

[Lucas_Olmedo]

Hi, I tried to create a histogram but when running the code I received the message:

hist("Year")
Error in hist.default("Year") : 'x' must be numeric

When I checked the structure of my data frame, "Year" is defined as num , but when I check with class("Year") is said it is a character vector (code copied below). Can anyone explain why this happens and how can I change that? Thanks

str(Social_Enterprises_Trial)
tibble [287 × 6] (S3: tbl_df/tbl/data.frame)
Name : chr [1:287] ... County : num [1:287] 22 6 7 16 20 16 7 7 5 5 ...
Location : num [1:287] 1 1 1 2 1 2 1 1 1 2 ... Year : num [1:287] 1990 2015 2022 2007 1987 ...

class("Year")
[1] "character"

"Year" (among quotes) is not referring to a vector stored in memory, it is literally a character string. I think you actually want to do this instead

hist(Social_Enterprises_Trial$Year)

Have in mind that Year is a column in the Social_Enterprises_Trial data frame, it doesn't exist as an independent object on its own.
