R Error: ‘R’ is an unrecognized escape in character string starting “”C:R”

 

In this R tutorial you’ll learn how to deal with the Error: ‘R’ is an unrecognized escape in character string starting “”C:R”.

The content of the post looks as follows:

Here’s how to do it.

 

Example 1: Reproduce the Error: ‘\R’ is an unrecognized escape in character string starting “”C:\R”

The following syntax explains how to replicate the Error: ‘R’ is an unrecognized escape in character string starting “”C:R” in the R programming language.

Let’s assume that we want to import a CSV file to R using the read.csv function. Then, we might try to apply the read.csv function to a path that looks like this:

read.csv("C:\R\Users\Joach\Desktop\my directory\my file.csv")  # Backslash in path
# Error: '\R' is an unrecognized escape in character string starting ""C:\R"

Unfortunately, the RStudio console returns the Error: ‘R’ is an unrecognized escape in character string starting “”C:R”.

The reason for this is that the backslash that we have used in the path is an escape character, and we need to specify that somehow in R.

So how can we do that?

 

Example 2: Fix the Error: ‘\R’ is an unrecognized escape in character string starting “”C:\R”

This section illustrates how to handle the Error: ‘R’ is an unrecognized escape in character string starting “”C:R”.

As explained in the previous example, we have to deal with the fact that backslashes are considered as escape characters by R.

We can solve this problem by either specifying another backslash in front of each backslash, or we can simply use a forward slash instead of a backslash.

Consider the following R code:

read.csv("C:/R/Users/Joach/Desktop/my directory/my file.csv")    # Slash in path

The only difference compared to Example 1 is that we have used a slash instead of a backslash, and now it works fine.
