我想做一些类似日历图的事情，但是一个月多几个小时（而不是一年多几天）。我设法用 ggplot 做到这一点，但数据以错误的顺序填充。

我做了这个可重现的例子：

library(ggplot2)
library(scales)
device <- "test"
dat <- data.frame(matrix(nrow=31*24, ncol=2))
dat[,1] <- seq.POSIXt(from=(as.POSIXct("2016-12-01 00:00:00")), length.out=(31*24), by="1 hour")
dat[,2] <- seq(from=1, to=nrow(dat), by=1)
colnames(dat) <- c("Zeit", device)

dat$month<-as.numeric(as.POSIXlt(dat$Zeit)$mon+1)
dat$monthf<-factor(dat$month)
dat$monthf<-factor(dat$month,levels=as.character(1:12),labels=c("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"),ordered=TRUE)

dat$week <- as.numeric(format(dat$Zeit,"%W"))

dat$weekday = as.POSIXlt(dat$Zeit)$wday
dat$weekdayf<-factor(dat$weekday,levels=(c(1:6,0)),labels=(c("Mon","Tue","Wed","Thu","Fri","Sat","Sun")),ordered=TRUE)

dat$day <- as.numeric(format(dat$Zeit,"%d"))
dat$dayf<-factor(dat$day)

dat$hour <- as.numeric(format(dat$Zeit,"%H"))
dat$hourf<-factor(dat$hour)

plot(ggplot(dat, aes(hourf, week, fill = dat[2])) +
   scale_y_reverse() +
   geom_tile(colour = "white") +
   facet_wrap(monthf~weekdayf, ncol=7) +
   scale_fill_gradientn(colours=c("darkgreen", "green", "yellow", "red","darkred"),
                                               values=rescale(c(0, 0.25, 0.5, 0.75, 1)),
                                               guide="colorbar") +
   xlab("") + ylab("") + ggtitle(device)
