Answer 1

这个怎么样：

df <- data.frame(Date = rep("2006-12-01", 10),
                 Time = paste0(1:10, ":00:00"),
                 x = rnorm(10))

library(zoo)
df$Date <- as.POSIXct(paste(df$Date, df$Time), "GMT")
as.zoo(df[, c("Date", "x")])

# Date                x         
# 1  2006-12-01 01:00:00 -0.1386150
# 2  2006-12-01 02:00:00  1.8828398
# 3  2006-12-01 03:00:00  0.8736687
# 4  2006-12-01 04:00:00 -0.9145971
# 5  2006-12-01 05:00:00 -1.2449176
# 6  2006-12-01 06:00:00 -0.3599822
# 7  2006-12-01 07:00:00  1.3287747
# 8  2006-12-01 08:00:00  0.2926791
# 9  2006-12-01 09:00:00 -0.7015052
