如何在ggplot中应用中断?
How to apply break in ggplot?
我有一个范围从 0 到 500 的栅格数据。我已经在我的数据上应用了百分位数,我的代码如下所示。我想在我的代码上应用中断,因为有时我只需要 200-500 的值,所以没有序列选项和中断我不能这样做。
**breaks = seq (0, 500, 50), limits = c(0, 500))+** # But I don't get where can i apply this in my code
我想在每 50 分钟后休息一次,例如 0-50、50-100 等等....
r <- raster("D:/research.tif")
centile90 <- quantile(r, 0.95)
df <- as.data.frame(as(r, "SpatialPixelsDataFrame"))
colnames(df) <- c("value", "x", "y")
ggplot(df, aes(x, y, z = value)) +
geom_contour_filled(bins = 8) +
geom_contour(breaks = centile90, colour = "orange",
size = 0.5) +
scale_fill_manual(values = hcl.colors(8, "YlGnBu", rev = TRUE)) +
scale_x_continuous(expand = c(0, 0)) +
scale_y_continuous(expand = c(0, 0)) +
theme_classic() +
theme()
您可以将中断向量传递给 geom_contour_filled
的 breaks
参数。
让我们首先创建一个值从 0 到 500 的栅格
library(raster)
r <- raster(t((volcano[,ncol(volcano):1] - 94) * 4.95))
range(r[])
#> [1] 0.00 499.95
df <- as.data.frame(as(r, "SpatialPixelsDataFrame"))
colnames(df) <- c("value", "x", "y")
现在我们这样称呼情节:
centile90 <- quantile(r[], 0.9)
# Define breaks vector
mybreaks <- seq(0, 500, 50)
ggplot(df, aes(x, y, z = value)) +
geom_contour_filled(breaks = mybreaks) +
geom_contour(breaks = centile90, colour = "orange",
size = 0.5) +
scale_fill_manual(values = hcl.colors(length(mybreaks) - 1, "YlGnBu", rev = TRUE)) +
scale_x_continuous(expand = c(0, 0)) +
scale_y_continuous(expand = c(0, 0)) +
theme_classic() +
theme()
