How to Convert a List of Character Number Groups to Numeric Values in R

If you're an R programmer, you may have encountered situations where your data is not in the format you need for analysis. One common scenario is having a list of numeric values represented as characters that require conversion into a numeric format. In this post, we’ll explore how to convert a list of character number groups into a list of numeric values and present clear solutions to help you navigate this task efficiently.

The Problem: Character Lists to Numeric Lists

Imagine you have the following character list in R:

In its current state, each group of numbers is treated as a single character string. This format is not ideal for mathematical operations and analytics, as we need the numbers to be individual numeric entities. Our goal is to convert this list into a structured numeric format that looks like this:

Now let’s dive into the solution!

Solution: Converting Character Lists to Numeric

Method 1: Using lapply and strsplit

One of the simplest ways to achieve this conversion is by employing the lapply function along with the strsplit function in R. Here’s how it works:

Split the Character Strings: The strsplit function will divide each string into its constituent parts based on the separator, which in this case is a comma (,).

Convert to Numeric: After splitting, we utilize as.numeric to convert the resulting character vectors into numeric vectors.

Wrap in lapply: The lapply function applies our specified operations to each element of the list.

Here’s the R code:

Method 2: Using type.convert

Another effective method utilizes the type.convert function. This function can handle the conversion while maintaining the structure of the list.

Comparing the Methods

Both methods will yield similar results, but they have slight variations in their implementations:

lapply(strsplit(...)) gives you more control over the functions you apply.

type.convert(...) automatically infers the type and performs the conversion, which might be benefical if you're working with data types beyond just numbers.

Final Thoughts

Converting a list of character number groups into numeric values is a common task that can be easily accomplished using R. By utilizing lapply with strsplit, or opting for type.convert, you can transform your data into a usable format for analysis smoothly.
