我试图绘制一个颜色轮廓图,显示 x 轴上的时间、 y 的深度和 z 值的温度。 时间以 :
"2011-01-01 00:01"
i.e. "%Y-%m-%d %H:%M"
是否有一种方法从这些图中生成颜色等宽图图, 并使用
filled.contour(Time,Depth,temp)
例如:
time <- c("2011-01-01 01:00", "2011-01-01 02:00", "2011-01-01 03:00",
"2011-01-01 04:00")
depth <- seq(1,10,by = 1)
seq1 <- seq(1:40)
temp <- matrix(seq1, 10)
每个临时列代表不同的时间,每一行代表不同的深度。
这对我管用:
time2 <- as.POSIXct(time)
结果:
> time2
## [1] "2011-01-01 01:00:00 EST" "2011-01-01 02:00:00 EST"
## [3] "2011-01-01 03:00:00 EST" "2011-01-01 04:00:00 EST"
现在绘制它 :
filled.contour(time2,depth,t(temp))
