在R中，如何用行名和列名创建包含在"matrix“或"dataframe”设置中的绘图？

row_names <- rownames(matrix_or_dataframe)
col_names <- colnames(matrix_or_dataframe)

# 使用image()函数创建热图
image(matrix_or_dataframe, xaxt = "n", yaxt = "n", xlab = "", ylab = "")
axis(1, at = 1:length(col_names), labels = col_names)
axis(2, at = 1:length(row_names), labels = row_names)

# 使用heatmap()函数创建热图
heatmap(matrix_or_dataframe, xlab = "", ylab = "")

library(ggplot2)

# 创建数据框
df <- data.frame(matrix_or_dataframe)

# 创建绘图
ggplot(df, aes(x = row_names, y = col_names, fill = value)) +
  geom_tile() +
  theme(axis.text.x = element_text(angle = 90, vjust = 0.5, hjust=1))
