数据

df <- data.frame(x = 1:10, y = 1:10, f = c(rep("A", 5), rep("B", 5)))

做图

1. 散点图 (scatter plot)

# scatter plot
scatter_plot <- function(df, metadata) {identical(rownames(df), rownames(metadata))data <- cbind(df, metadata)cor_res <- cor(data$x, data$y, method = "spearman")x <- unlist(data$x)y <- unlist(data$y)plot(x, y, pch = 19, xlab = "X", ylab = "Y") +abline(lm(x ~ y), col = "purple", lwd = 3) + # Regression linetext(0.4 * max(data$x), 0.8 * max(data$y), paste("Correlation:", round(cor_res, 2))) # Pearson correlation
}scatter_plot(df, metadata)

2. 柱状图 (bar plot)

3. 堆积柱状图 (stacked bar chart)

4. 热图 (heatmap)
