To create a graph in base R with multiple shades of a particular color, we can follow the below steps −First of all, create color shades using colorRampPalette then plot a graph.Use the color shades to create the graph.Example 1Create the color shadesUsing colorRampPalette function to create the color shades between red and darkred color then creating the plot −Color
Read MoreHow to create a sample or samples using probability distribution in R?
A probability distribution is the type of distribution that gives a specific probability to each value in the data set. For example, if we have a variable say X that contains three values say 1, 2, and 3 and each of them occurs with the probability defined as 0.25, 0.50, and 0.25 respectively then the function that gives the probability of occurrence of each value in X is called the probability distribution. In R, we can create the sample or samples using probability distribution if we have a predefined probabilities for each value or by using known distributions such as ...
Read MoreHow to create boxplot using ggplot2 without box border in R?
We know that the middle portion of a boxplot is a box which is covered with black border but we can remove that border from the plot by defining the aesthetics of the boxplot with color argument. We can follow the below steps to create such type of boxplot −Creating a data frame.Then create a default boxplot.Loading ggplot2 package and creating the same boxplot without box border.Create the data frameLet's create a data frame as shown below −x

Read MoreHow to find the row sums by excluding a column in R data frame?
Suppose we have a numerical column in an R data frame that we do not want to include our analysis due to some characteristics such is similarity or distinction with the rest of the data then we might want to exclude that column from the analysis. One such situation would be finding the row sums by excluding a column. For this purpose, we can use the below steps −First of all, creating a data frame.Finding the row sums with the help of mutate function of dplyr package and setdiff function in base RCreate the data frameLet's create a data frame ...
