Creating Data frame and accessing rows and columns. Data frames is a convenient and popular data object to perform various analyses. Import statements such as read.csv() imports data into R as a data frame, so its just convenient to keep it that way. Now lets create a data frame with the vectors we’d created earlier.Therefore, the quadratic model is either as accurate as, or more accurate than, the linear model for the same data. Recall that the stronger the correlation (i.e. the greater the accuracy of the model), the higher the R^2. So the R^2 for the quadratic model is greater than or equal to the R^2 for the linear model. Have a blessed, wonderful day!Using statistics, you can help solve real-world problems in business, engineering, the sciences, and many other fields.
