按索引合并任意数量不同长度的xts对象

# 安装并加载xts包
install.packages("xts")
library(xts)

# 创建示例数据
data1 <- xts(rnorm(5), as.Date('2023-01-01') + 0:4)
data2 <- xts(rnorm(3), as.Date('2023-01-03') + 0:2)
data3 <- xts(rnorm(4), as.Date('2023-01-02') + 0:3)

# 按索引合并
merged_data <- merge(data1, data2, data3)

# 查看合并后的数据
print(merged_data)

# 对齐时间索引
data1_aligned <- align.time(data1, n=60)
data2_aligned <- align.time(data2, n=60)
data3_aligned <- align.time(data3, n=60)

# 再次合并
merged_data_aligned <- merge(data1_aligned, data2_aligned, data3_aligned)

# 确保数据类型一致
data1 <- xts(as.numeric(rnorm(5)), as.Date('2023-01-01') + 0:4)
data2 <- xts(as.numeric(rnorm(3)), as.Date('2023-01-03') + 0:2)
data3 <- xts(as.numeric(rnorm(4)), as.Date('2023-01-02') + 0:3)

# 合并
merged_data <- merge(data1, data2, data3)
