File Cannot be Found Message When Knitting with R Markdown

Introduction

Knitting a document in R Markdown can sometimes lead to frustrating errors, particularly when trying to include images. In this article, we will explore the common error “Cannot find the file(s): ‘skimr - data summary.png’” and provide solutions for overcoming it.

Understanding File Paths

Before we dive into solving the issue, let’s first understand how file paths work in R Markdown. When you create an image using knitr::include_graphics(), Hugo (or RStudio Server) expects a fully qualified path to the image file. This includes both the directory and filename.

File Existence Check

In your case, you’ve checked that the file exists when you use the “file.exists()” function in R. However, the issue persists when knitting the document using R Markdown.

Possible Causes

There are a few possible reasons why this might be happening:

The image file is not located where the knitting process expects it to be.
The path to the image file is incorrect or missing critical components (e.g., drive letter, backslash, forward slash).
There’s an issue with the way you’re calling knitr::include_graphics().

Solving the Issue

1. Provide Full Path

One common solution for this error is to provide the full path to your image file when using knitr::include_graphics(). You can do this by adding the following code:

```r
# knitr includes graphics library
library(knitr)

# include the image with full path
knitr::include_graphics("C:/Users/HP/OneDrive/Documents/R/cyclistic_bike_share_analysis/skimr - data summary.png")

2. Use Hugo’s `include` Function

Alternatively, you can use Hugo’s built-in include function to include your image file. Here is an example of how to do this:

![SkimR Data Summary](/path/to/skimr-data-summary.png)

In this case, the /path/to/ part should be replaced with the actual path to your image file.

3. Verify File Location

Ensure that the image file is located in a directory where Hugo (or RStudio Server) expects it to find files. This might involve moving the file to a location like public/images/.

Conclusion

Resolving the “Cannot find the file(s): ‘skimr - data summary.png’” error when knitting can sometimes be a challenge, but by understanding how file paths work in R Markdown and trying out the solutions above, you should be able to successfully include your images.

Best Practices for Image Inclusion

To avoid such errors in the future:

Always provide the full path to your image files.
Verify that the image file is located where the knitting process expects it.
Consider using Hugo’s include function for image inclusion.

Troubleshooting Tips

If you’re still experiencing issues, here are some additional troubleshooting tips:

Check if the issue persists when using a different image or document.
Verify that the file exists and is correctly named.
Try including the image in a different location to rule out issues with Hugo’s configuration.
