我的样本中有多少簇？在R中合并两个数据帧

# 创建两个数据帧
df1 <- data.frame(ID = c(1, 2, 3), Value1 = c(10, 20, 30))
df2 <- data.frame(ID = c(2, 3, 4), Value2 = c(40, 50, 60))

# 使用merge()函数合并两个数据帧
merged_df <- merge(df1, df2, by = "ID")

library(dplyr)

# 创建两个数据帧
df1 <- data.frame(ID = c(1, 2, 3), Value1 = c(10, 20, 30))
df2 <- data.frame(ID = c(2, 3, 4), Value2 = c(40, 50, 60))

# 使用dplyr包中的join函数合并两个数据帧
merged_df <- df1 %>% inner_join(df2, by = "ID")
