Let’s say we want to display tilde sign at a particular position in histogram using ggplot2 graph. In this situation, we can use geom_text function and pass all the text with label argument inside aes where tilde will be written as %~%.For Example, if we want to display X follows ... Read More

We can create a circle in R by using draw.circle function of plotrix package and if we want to have vertical lines inside the circle then density and angle arguments will be used. The density argument will create the lines and angle argument will set the direction of those lines.For ... Read More

To create a 90-degree arc in R, we can use draw.arc function of plotrix package where we can use deg2 argument. Since, a 90-degree can be drawn in four ways; we need to pass the degree depending on the position of the arc we want to display.Check out an Example ... Read More

We can create a circle in R by using draw.circle function of plotrix package and default border color of the circle is black. If we want to change the border color of a circle then we can use border argument and pass the desired colors.For Example, if we want to ... Read More

To fill bars in a bar plot using ggplot2 in R with colors based on frequency, we can use fill argument with count.For Example, if we have a data frame called df that contains a single column X that contains repeated values and we want to create bar plot of ... Read More

If we have a single row for a matrix then creation of a matrix with equal rows can be easily done with the help of rep function and if we do not have the row then we would need to pass the row value inside rep function.Check out the below ... Read More

To impute missing values by random value for a single column in R, we can use impute function from Hmisc package.For example, if we have a data frame called that contains a column say C which has some missing values then we can use the below given command to fill ... Read More
