tidyverse
1

Hello, Im trying to setup a regression analysis for a school project,

However im getting an error when trying to run some code
Here's what I've got so far.

install.packages("tidyr")
install.packages("tidyverse")
install.packages("ggplot2")
install.packages("rlang")
library(tidyverse)
library(ggplot2)
library(rlang)
library(tidyr)
Df = NaturalGasCSV

head(Df)
Df$Year
Df$Volume

Dummy Variable for CUSFTA Agreement Enactment date of 1989

Df$CUSFTA = Df$Year >= 1989

Df = mutate(Df, NaturalGasCSV = Year >= 1989)
select(Df, Year, NaturalGasCSV)

** This is the error message Im getting **

Df = mutate(Df, CUSFTA = Year >= 1989)
Error in mutate(Df, CUSFTA = Year >= 1989) :
could not find function "mutate"

Any help would be greatly appreciated

Hi, that is a bit strange as mutate should be loaded in the tidyverse.

What do you get when you run sessionInfo()?
