How can I use color theory in R visualizations?

Color theory can enhance your R visualizations by using color palettes that convey meaning and improve readability. You can use packages like 'ggplot2' and 'RColorBrewer' to apply color schemes effectively.

What are some good color palettes for data visualization?

Some popular color palettes include 'Set1', 'Set2', and 'Viridis'. 'Viridis' is particularly good for accessibility as it is colorblind-friendly.

How do I implement a color palette in ggplot2?

You can implement a color palette in ggplot2 using the scale_color_manual() function. For example, you can specify your colors like this: scale_color_manual(values = c('red', 'blue', 'green')).

Can you give me an example of a plot using color theory?

Sure! Here's a simple example:

library(ggplot2)

# Sample data
data <- data.frame(x = 1:10, y = rnorm(10), group = rep(c('A', 'B'), each = 5))

# Plot with color palette
ggplot(data, aes(x, y, color = group)) + 
  geom_point(size = 3) + 
  scale_color_manual(values = c('A' = 'blue', 'B' = 'orange')) + 
  theme_minimal()
