Hello,
I am trying to practice R programming with 'airquality' that is a pre-loaded dataset in Rstudios.
I uploaded the dataset. But the problem is that whenever I try to give any logical statement like AND, OR or NOT, it shows an error message.
head(airquality)
Ozone Solar.R Wind Temp Month Day
1 41 190 7.4 67 5 1
2 36 118 8.0 72 5 2
3 12 149 12.6 74 5 3
4 18 313 11.5 62 5 4
5 NA NA 14.3 56 5 5
6 28 NA 14.9 66 5 6
Solar.R>100 & Wind>10
Error: object 'Solar.R' not found
Could anyone please help me by pointing out the mistake I am doing, or the step I am missing?
Thanks in advance.
