package. After loading the ggplot2 package with the library() function, I can run

The following code creates a scatterplot of ‘votes’ and ‘rating’ from the movies dataset in the ggplot2 package. After loading the ggplot2 package with the library() function, I can run 1qplot(votes, rating, data = movies)How can I modify the the code above to add a smoother to the scatterplot? qplot(votes, rating, data = movies) +…

When I run the following code I get an error: 1234 library(ggplot2) library(ggplot2movies) g <- ggplot(movies, aes(votes, rating)) print(g) I was expecting a scatterplot of ‘votes’ and ‘rating’ to appear. What’s the problem?

When I run the following code I get an error: 1234library(ggplot2)library(ggplot2movies)g <- ggplot(movies, aes(votes, rating))print(g)I was expecting a scatterplot of ‘votes’ and ‘rating’ to appear. What’s the problem? The object ‘g’ does not have a print method. The dataset is too large and hence cannot be plotted to the screen. There is a syntax error…

Load the `airquality’ dataset form the datasets package in R

Load the `airquality’ dataset form the datasets package in R 12library(datasets)data(airquality)I am interested in examining how the relationship between ozone and wind speed varies across each month. What would be the appropriate code to visualize that using ggplot2? 1qplot(Wind, Ozone, data = airquality, facets = . ~ factor(Month)) 1qplot(Wind, Ozone, data = airquality) 12airquality =…

Which of the following functions can be used to annotate the panels in a multi-panel lattice plot?

Annotation of plots in any plotting system involves adding points, lines, or text to the plot, in addition to customizing axis labels or adding titles. Different plotting systems have different sets of functions for annotating plots in this way. Which of the following functions can be used to annotate the panels in a multi-panel lattice…
