使用ggplot軟件包在R中命名軟件倉

Question

我正在使用ggplot軟件包命名R中的軟件倉;我嘗試使用names.args選項，但沒有奏效。

Answer 1

創建ggplot一個數據幀，然後條形圖，使用ggplot標籤：

# my example uses some raster data 
require(ggplot2) 
require(raster) 
r <- raster("myraster.tif") 
f <- hist(r, breaks=10) 
dat <- data.frame(counts= f$counts,breaks = f$mids) 

ggplot(dat, aes(x = breaks, y = counts, fill =counts)) + 
    geom_bar(stat = "identity")+ 
    scale_x_continuous(breaks = f$mids,labels = c("0 to 0.1","0.1 to 0.2","0.2 to 0.3","0.3 to 0.4","etc","etc","etc","etc","etc","etc"))
