绘制作物日历

Question

我有一个csv文件(crop_calendar.csv),其中包含有关特定区域中作物的开发阶段的信息.基本上每行都有以下结构:

crop_name   sowing_dat    emergence_date  flowering_date  maturity_date  harvest_date

例如:

Winter_wheat    18.08   28.08   24.06   30.07   3.08
Winter_rye      18.08   28.08   15.06   23.07   29.07
Spring_wheat    27.04   10.05   1.07    4.08    7.08
Spring_barley   27.04   12.05   27.06   1.08    5.08

现在,我想将这些信息放在一个看起来像这样的图形中:

知道如何使用大量的作物(行)和不同的位置吗？

这是一个例子,假设你有播种的day.of.year()和每个作物和每个国家的三个时期的持续时间(以天为单位).

set.seed(12345)

  Crop = paste("Crop", LETTERS[1:8]),

#day.of.year of sowing
rawdata$Sowing <- runif(nrow(rawdata), min = 0, max = 365)
#number of days until mid season
rawdata$Midseason <- runif(nrow(rawdata), min = 10, max = 30)
#number of days until harvest
rawdata$Harvest <- runif(nrow(rawdata), min = 20, max = 150)
#number of days until end of harvest
rawdata$Harvest.end <- runif(nrow(rawdata), min = 10, max = 40)
