This function creates a tile plot of the foci (cluster) identified by the AFSD function.
It colors each cell in a foci and labels the centroid of each cluster with the foci ID.
The 'ggplot2' package is used for the plot, and will be automatically installed if not already present.
Arguments
- df
A dataframe containing at least three columns: 'x', 'y', and 'cluster_id'.
'x' and 'y' are spatial coordinates and 'cluster_id' is the cluster identifier
to which each cell belongs.
Value
A ggplot object with the scatter plot of foci (clusters).
Examples
df <- data.frame(x = sample(1:100, 500, replace = TRUE),
y = sample(1:100, 500, replace = TRUE),
i = sample(0:1, 500, replace = TRUE, prob = c(0.7, 0.3)))
# Perform the AFSD
result <- AFSD(df)
# Plot the foci
plot_AFSD(result[[3]])
