For this assignment \(airquality\) datasets available in R is used.
The effects of Wind, Solar Radiation and Ozone level on Temperature throughout the months from May to September 1973 will be observed graphically.
The following packages are used for the analysis.
library(plotly) library(ggplot2) library(dplyr) library(tidyr)
str(airquality)
'data.frame': 153 obs. of 6 variables: $ Ozone : int 41 36 12 18 NA 28 23 19 8 NA ... $ Solar.R: int 190 118 149 313 NA NA 299 99 19 194 ... $ Wind : num 7.4 8 12.6 11.5 14.3 14.9 8.6 13.8 20.1 8.6 ... $ Temp : int 67 72 74 62 56 66 65 59 61 69 ... $ Month : int 5 5 5 5 5 5 5 5 5 5 ... $ Day : int 1 2 3 4 5 6 7 8 9 10 ...
