For this, we can use the different class functions provided by the R programming language. The following R code constructs an empty data frame with three columns that have the classes numeric, character, and factor.data4 <- data.frame(A = numeric(), # Create data frame B = character(),...
Code README strict The goal of strict to make R behave a little more strictly, making base functions more likely to throw an error rather than returning potentially ambiguous results. library(strict)forces you to confront potential problems now, instead of in the future. This has both pros and...
to make the default target a brief help command. However, maintaining the help text by hand is always a problem. To avoid this, you can gather the available commands directly frommake’s rules database. The following target will present a sorted four column listing of the availablemaketargets...

Histograms are visualizations that show frequency distributions across continuous (numeric) variables. Histograms allow us to see the count of observations in data within ranges that the continuous variable spans. Housing Data We will first need to import the ggplot2 library using the library function...
it gives me the row percentages and the column percentages for each category. Moreover, ‘prop.t’ gives me a table percentage as well. This information is particularly useful when you want to compare one variable with another,tabulateother numeric vector actions, or find something like the phi...

We constructed a data frame with a numeric and a character column by running the prior code. The ggplot2 package must then be loaded. How to Use the Multinomial Distribution in R? install.packages("ggplot2") library("ggplot2") We can now use the geom col method to create a conventio...
Corner coordinates in the output space, specified as an N-by-2 numeric matrix. The first column represents the coordinates of one corner and the second column represents the coordinates of the opposite corner. outCorners(1,k) and outCorners(2,k) must be different unless inCorners(1,k) and...
