We can also use the cor function to calculate other types of correlation coefficients. This example explains how to compute a Kendall Correlation:cor(x, y, method = "kendall") # Kendall correlation # [1] 0.4719
Example 3: lapply with Self-Defined Function In this section, I’ll demonstrate how to use a self-defined function with lapply. You can either define the function before lapply and use it similar to the mean function before. Alternatively, as shown below, you can also define the function wi...
If you are needing to do a square root the function is sqrt in r. It has the format of sqrt(x) where “x” is the values whose squareroots are being calculated. This formula will find a positive square root when dealing with either an integer or double-precision numeric value. However...

II. R square value using summary() function We can even make use of thesummary() functionin R to extract the R square value after modelling. In the below example, we have applied the linear regression model on ourdata frameand then usedsummary()$r.squaredto get the r square value. ...
