  1. Import the data into R.
  • How many observations are there in the dataset?
  • How many observations are there with a fire (i.e., area>0)
  • How many observations are there with a rain (i.e., rain>0)
  • How many observations are there with both a fire and a rain?

 2.Show the columns month, day, area of the all the observations.

 3. Show the columns month, day, area of the observations with a fire.

 4.How large are the five largest fires (i.e., having largest area)

 a.What are the corresponding month, temp, RH,wind, rain area?

 b.Add one column to the data indicating whether a fire occurred for each   observation (True for area >0 and False for area ==0) (Use Mutate function)

5.Create the following to display the outliers from the below vector.

    -plot 

   – boxplot

Also mention the numbers that are outliers in this vector.

(1,2,50,45,67,200,230,55,56,49)

6. Using the dplyr approach, perform the following actions from ‘iris’

  a) select the columns  Sepal.Length, Sepal.Width, Petal.Length,Petal.Width

 b) filter the iris data for Species = “setosa” or “virginica”
