使用ggplot软件包在R中命名软件仓

Question

我正在使用ggplot软件包命名R中的软件仓;我尝试使用names.args选项，但没有奏效。

Answer 1

创建ggplot一个数据帧，然后条形图，使用ggplot标签：

# 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"))
