Example text

The preceding code shows critic ratings and acquisition cost sorted in ascending order. The order command is used instead of the sort command. The head command prints the first six observations by default from the sorted dataset. The number 1:5 in the second argument after the order command implies that we want to print the first six observations and five variables from the ArtPiece dataset. If it is required to print 10 observations from the beginning, head(i2, 10) can be executed. The dataset does not have any missing values; however, the existence of NA or missing values cannot be ruled out from any practical dataset.

The following sample code and example show how to check normality graphically and interpret the same. 483982 ggplot(data=Cars93, aes(Cars93$Price)) + geom_density(fill="blue") [ 44 ] Exploratory Data Analysis with Automobile Data From the preceding image, we can conclude that the price variable is positively skewed because of the presence of some outlier values on the right-hand side of the distribution. The mean of the price variable is inflated and greater than the mode because the mean is subject to extreme fluctuations.
