Since at least Roman times, the concept of cultivating plants in controlled environments has been around.

When applying PCA, interpreting the relationship between the principal components is crucial. However, analyzing more than two components can get tricky. Fortunately, PCA 3D plots can help.

A 3D plot visualizes high-dimensional data reduced to three principal components, revealing patterns, clusters, and outliers that may not be visible in 2D plots. It makes the data more interpretable and provides deeper insights into the underlying structure.

Here's a quick guide to implementing a 3D PCA plot in R:

1️⃣ Prepare Data: Clean and preprocess your data, ensuring all variables are numeric by removing any categorical variables.

2️⃣ Perform PCA: Apply PCA to the preprocessed data using prcomp() and extract the component scores.

3️⃣ Create the 3D Plot: Use plot3d() from the rgl library to visualize the results in three dimensions, creating an interactive 3D scatter plot.

For a detailed step-by-step tutorial, check out my tutorial created in collaboration with Paula Villasante Soriano: https://t.co/zgb5H5zuyD

I have also developed an extensive online course on PCA, which explains the theoretical concepts and practical applications in R programming. Further details: https://t.co/DUfoAHuxxD

Vienna Dioscurides assumed to have been created in Constantinople around 500, is one of the most famous manuscripts of late antiquity. Its main section contains images of 383 alphabetically arranged medicinal plants; the corresponding text by the greek physician Dioscurides.

🍃🏷️ PART 2 – See how a collection is made for a Herbarium specimen! We're back in the Sarawak rainforest with Tropical Botanist @Scaphium to see how a botanical collection is pressed in the field before it is ultimately incorporated into the Sarawak and Edinburgh herbaria.
