I have 100 images saved as .png files. I would like to display them all as a 10x10 image grid, so that each image has its own title and the image grid shares a single title. I would like to use R Markdown to do this. it's possible?
Yes, it's possible to do this in R Markdown. A practical option is to use packages like knitr , gridExtra , patchwork , or cowplot to load the 100 images and arrange them in a 10x10 grid. Each image can have its own title (for example, using the filename or a custom tag), and the entire set can be given a general title using the composition functions of the chosen package.
If the goal is to generate an HTML or PDF report, automating the loading of images from a directory and building the grid using a loop is usually the most scalable solution, avoiding manually inserting the 100 images into the document.
