Manipulating Data Frames in R

Data Science Using R, Data Science
Learn To Manipulate Data Frames Using The “mtcars” Dataset Below is an introduction to programming with r, all code in this exercise is only using base r and no other libraries are needed. Task 1: Create a new column to find Displacement per Cylinder  Create a new variable (DisplacementPerCylinder), to calculate the total displacement per cylinder in cubic inches for each vehicle from the mtcars dataset. # "str" allows you to display the internal structure of an R object str(mtcars) ## 'data.frame': 32 obs. of 11 variables: ## $ mpg : num 21 21 22.8 21.4 18.7 18.1 14.3 24.4 22.8 19.2 ... ## $ cyl : num 6 6 4 6 8 6 8 4 4 6 ... ## $ disp: num 160 160 108 258 360 ... ## $ hp : num 110 110 93 110 175 105 245 62 95 123 ... ## $ drat: num 3.9 3.9 3.85 3.08 3
