What techniques can be used in R to visualize high-dimensional data?
- Scatter plots with color or size encoding
- Parallel coordinate plots
- Dimensionality reduction techniques like PCA or t-SNE
- All of the above
All of the mentioned techniques can be used in R to visualize high-dimensional data. Scatter plots can encode additional dimensions through color or size. Parallel coordinate plots can show relationships between multiple variables. Dimensionality reduction techniques like PCA or t-SNE can project high-dimensional data into lower dimensions for visualization.
