我有一个名为"数据"的时间序列数据集,其中包含多年采样日期内几口井的水位数据.data.frame的头部如下所示:
Date Well Elev 1 2002-05-23 MW-3 929.04 2 2002-05-29 MW-3 929.39 3 2002-05-31 MW-3 929.37 4 2002-06-05 MW-3 929.36 5 2002-06-12 MW-3 NA 6 2002-06-13 MW-3 929.47 7 2002-06-19 MW-3 929.42 8 2002-06-26 MW-3 930.02 9 2002-07-05 MW-3 930.00
我正在尝试使用ggplot来绘制每个井的水位随时间的变化,这样我的x轴是"日期",我的y轴是"高程",每个井都以不同的颜色绘制.我用下面的代码创建了这个情节,这令我满意.
我的问题是我试图用geom_rect叠加灰色矩形来显示井泵的开启时间.我认为我非常接近,但我必须做日期格式化错误(？),因为我不断收到以下错误:
错误:输入无效:date_trans仅适用于Date类的对象
有帮助吗？提前致谢!
这是我的代码:
#Import and fix up data
Data = read.csv("water_elevation_for_R_date.csv", stringsAsFactors=FALSE)
colnames(Data)[1] <- "Date"
Data$Date = as.Date(Data$Date, format = "%m/%d/%Y")
Data$Well <- as.factor(Data$Well)
Data$Elev <- as.numeric(Data$Elev)
#Load ggplot and scales
library(ggplot2)
library(scales)
#Create graph
ggplot(data= Data, aes(x = Date, y = Elev, group = Well, colour = Well)) +
geom_line(size = 0.75) +
xlab("") + ylab("Elevation (ft.)") +
scale_color_brewer(palette = "Spectral") +
scale_x_date(breaks = date_breaks("2 year"),
labels = date_format("%Y")) +
theme_bw()+
theme(plot.background = element_blank(),
panel.grid.major = element_blank(),
panel.grid.minor = element_blank(),
panel.border = element_blank(),
axis.line.x = element_line(color = "black"),
axis.line.y = element_line(color = "black")) +
geom_rect(data = Data,
aes(xmin = "2004-04-29",
xmax = "2004-12-20",
ymin = -Inf,
ymax = Inf),
fill = "gray",
alpha = 0.5)
micstr.. 21
这个问题似乎出现在你所在的geom_rect地区(如果没有这个问题,那就是情节).此站点上的其他"date_trans"错误指向需要设置日期as.Date.所以是的,你是在正确的调试区域.这有效:
在xmin和xmax调用中包含最小值和最大值geom_rect:
aes(xmin = as.Date("2004-04-29", "%Y-%m-%d"),
xmax = as.Date("2004-12-20", "%Y-%m-%d"),

我仅在@YourEconProf建议的情况下创建了三条数据线.
