round_any Function of plyr Package in R (2 Examples)
The tutorial is structured as follows:
Let’s dive into it.
Exemplifying Data & Software Packages
We’ll use the following data as basement for this R tutorial:
set.seed(562981) # Create random vector x <- rnorm(10) x # Print random vector #  0.4727372 -0.7717060 -0.9445741 0.6140858 0.2909179 0.1659105 #  -0.2909570 1.1854541 -0.4401599 0.3069997
Have a look at the previous output of the RStudio console. It shows that our example data contains ten randomly distributed numeric values.
install.packages("plyr") # Install & load plyr library("plyr")
We are set up! Let’s move on to the application of the round_any function in R.
Example 1: Round with Accuracy of 1 Using round_any() Function of plyr Package
Generally speaking: The round_any function rounds to a multiple of any number that we specify within the round_any function.
This example illustrates how to round to the closest multiplier of 1 (in other words: an accuracy of 1) using the round_any function.
For this, we have to specify the name of our data object (i.e. x) as well as the accuracy (i.e. 1):
x_round1 <- round_any(x, 1) # Apply round_any x_round1 # Print rounded vector #  0 -1 -1 1 0 0 0 1 0 0
The previous output shows that we have created a new data object called x_round1, where the values in our input vector x have been rounded to the closest multiplier of the value 1.
Example 2: Round with Accuracy of 0.25 Using round_any() Function of plyr Package
The round_any function can be used to round to basically any multiplier you want.
Example 2 illustrates how to round to the closest multiplier of 0.25:
x_round2 <- round_any(x, 0.25) # Apply round_any x_round2 # Print rounded vector #  0.50 -0.75 -1.00 0.50 0.25 0.25 -0.25 1.25 -0.50 0.25
Note that the examples of this tutorial have used the round function to round our data, i.e. the default rounding function of round_any. However, you may change the f argument of the round_any function to floor or ceiling, in case you prefer to use another rounding function instead.
