Answers:
Please note that airquality is a built-in dataset in RStudio. You can simply use this by calling its name as and when needed. For instance, I am trying to plot the two variables of this dataset as given below:
(airquality$Solar.R, airquality$Ozone)
its still not working

Please see whether you are able to view the data by executing View(airquality).

I am assuming that you have installed R and RStudio on your machine. Then, you are trying to load the data in RStudio.

library(dplyr)
# use Built In data set airquality. Using select function,
#select the variables Ozone, Wind, Temp in this dataset.
View(airquality)
airqualitySOW <- select(airquality$Ozone, airquality$Wind, airquality$Temp)
View(airqualitySOW)
View(mtcars)
mtcars <- read.csv("mtcars.csv")
mtcarsR <- rename( mtcars, MilePerGallon = "mpg" ,
Cylinder = "cyl")
View(mtcarsR)
for the bold text in above I get output as
> airqualitySOW <- select(airquality$Ozone, airquality$Wind, airquality$Temp)
Error in UseMethod("select_") :
no applicable method for 'select_' applied to an object of class "c('integer', 'numeric')"
> View(airqualitySOW)
>
airqualitySOW <- select(airquality,c(Ozone, Wind, Temp))
