To create a table of frequency for range of values in an R data frame column, we can follow the below steps −First of all, create a data frame.Then, use table function with cut function to create the table of frequency for range of values.Example 1Create the data frameLet's create a data frame as shown below − Live Demox
To create density plot with manually setting the colors of categories, we can follow the below steps −Frist of all, create a data frame.Load ggplot2 package and creating the density plot for the categories.Create the density plot for the categories in the data frame by using scale_fill_manual function.Create the data frameLet's create a data frame as shown below − Live Democategories
To find the row minimum excluding zero in R data frame returning 0 if all 0, we can follow the below steps −First of all, create a data frame.Then, find the row minimum by excluding zero using if function with apply function.Example1Create the data frameLet's create a data frame as shown below − Live Demox1
To create a horizontal line in ggplot2 graph with different in R, we can follow the below steps −First of all, create a data frame.Then, create a plot using ggplot2 using geom_hline function having horizontal line.After that, create the same plot with line color defined with col argument.Create the data frameLet's create a data frame as shown below − Live Demox
To perform Friedman test in R, we can follow the below steps −First of all, create a matrix.Then, use friedman.test function to perform the Friedman test.Example1Create the matrixLet's create a data matrix as shown below − Live DemoFirst
To divide matrix row values by row sum in R, we can follow the below steps −First of all, create a matrix.Then, use apply function to divide the matrix row values by row sum.Create the matrixLet’s create a matrix as shown below − Live DemoM
