我有一个数据集,其中包含按国家和年份列出的儿童死亡人数(cdeaths)数据。如何为每个国家生成单独的散点图(每年的cdeaths),而不必手动进行?我有186个国家,所以我想知道是否有一种方法可以通过因素来做到这一点。

数据集如下所示

给你:

> library(dplyr)
> library(tibble)

> lisa <- read.table("D:/R/SO/lisa.txt",header=TRUE) # my path
> df <- as.tibble(lisa) 
> df
# A tibble: 97 x 3
   country      year   sab
   <fct>       <int> <dbl>
 1 Afghanistan  2015  50.5
 2 Afghanistan  2014  45.2
 3 Afghanistan  2011  39.9
...etc
# ... with 87 more rows

你可以做你想做的事 facet_wrap 在里面 ggplot2 :

> df %>% group_by(country) %>% 
         ggplot(aes(x=year,y=sab)) + geom_point() + 
         facet_wrap(~country)

它产生以下结果:

实际上,我还没有对一个包含100多个分类变量值的数据集执行此操作,所以不确定它将如何扩展。网上有很多资源可以帮助您调整 ggplot2图 参数。。。只要记住这就像Photoshop。。。你总是要分层思考。希望这有帮助!
