R correlation plot visual

Hi, ChristianAU 

To change the color of the text within the red line to white in your R script visual, you need to adjust the text label color parameters in the corrplot function. Specifically, you need to make sure all text elements in the plot are set to white. Here’s the updated script:

# Load necessary libraries
library(ggplot2)
library(reshape2)
library(corrplot)

# Ensure that the dataset is not empty
if(nrow(dataset) > 0) {
    # Compute the correlation matrix
    cor_matrix <- cor(dataset, use = "complete.obs")
    
    # Increase plot size and adjust margins for better readability
    par(mar = c(4, 4, 2, 2), oma = c(2, 2, 2, 2), mfrow = c(1, 1))
    options(repr.plot.width=10, repr.plot.height=8)
    
    # Define custom color palette
    custom_col <- colorRampPalette(c("#8B0000", "#FFD700", "#006400"))(200)
    
    # Set plot background color and text color
    par(bg = "#003165", col.lab = "white", col.axis = "white", col.main = "white", col.sub = "white")
    
    # Plot the correlation matrix using corrplot with custom settings
    corrplot(cor_matrix, method = "color", type = "upper", 
             tl.col = "white", tl.srt = 45, 
             addCoef.col = "white", number.cex = 0.7,
             col = custom_col,
             cl.cex = 1, cl.col = "white", cl.ratio = 0.2)
} else {
    plot.new()
    par(bg = "#003165")
    text(0.5, 0.5, "No data available", cex = 1.5, col = "white")
}
