In this tutorial, you will learn about what is recursive function in R, how to write a recursive function, what is nested function, how to use the … argument to the function. You will also learn about the scoping rules for functions in R, local and global variables in R. Recursive function in R Recursive …
In this tutorial, you will learn about what is user-defined function in R and how to create user-defined function in R. You will also learn about how the function is evaluated in R. What are functions in R? For every programming language, functions are the building blocks. Basically, functions are used to incorporate set of …
In this tutorial, we will discuss about tapply() function in R with some examples. tapply() function is available in base R package. The tapply() function in R The tapply() function is very useful to aggregate the data. That is tapply() function allows us to create a group summaries based on factor levels. The general syntax …
Mean, median and mode Mean, median, mode are the measures of central tendency. They are also known as averages. Averages are the measures which condense a huge set of numerical data into a single numerical value which is representative of the entire data. They give us an idea about the concentration of the values in …
In this tutorial, you will learn about what is harmonic mean, when harmonic mean is used and how to calculate harmonic mean in R. What is harmonic mean? Harmonic mean is a measure of central tendency. It is useful in finding the averages involving time, rate, price and ratio. Let $x_i, i=1,2, \cdots , n$ …
In this tutorial, you will learn about what is geometric mean, when to use geometric mean and how to calculate geometric mean in R. What is geometric mean? Geometric mean is a measure of central tendency. It is useful in averaging rate of changes when ratio changes are more important that the absolute changes. Let …
In this tutorial, you will learn about what is moment coefficient of kurtosis and how to calculate moment coefficient of kurtosis in R. Moment Coefficient of Kurtosis The literal meaning of kurtosis is peakedness or flatness of the data. The kurtosis measures how peaked or how flat the histogram is relative to the bell-shaped histogram. …
In this tutorial, you will learn about what is moment coefficient of skewness and how to calculate moment coefficient of skewness in R. Moment Coefficient of Skewness Skewness is a measure of symmetry. The meaning of skewness is "lack of symmetry". Skewness gives us an idea about the concentration of higher or lower data values …
In this tutorial, you will learn about what is Kelly’s coefficient of skewness and how to calculate Kelly’s coefficient of skewness in R. Kelly’s Coefficient of Skewness Skewness is a measure of symmetry. The meaning of skewness is "lack of symmetry". Skewness gives us an idea about the concentration of higher or lower data values …
In this tutorial, you will learn about what is Bowley’s coefficient of skewness and how to calculate Bowley’s coefficient of skewness in R. Bowley’s Coefficient of Skewness Skewness is a measure of symmetry. The meaning of skewness is "lack of symmetry". Skewness gives us an idea about the concentration of higher or lower data values …
