Question

我很难用R绘图。我希望我的条形图汇总deal_count列，但似乎没有这样做。不太清楚我在这里缺少什么。 deal_count值为“整数”。我试图用不同的类来总结该列，但没有运气。

也只是运行这个

sum(funded.agvc$deal_count)

不能产生适当的金额.....

ggplot(data=funded.agvc, aes(moved_date,deal_count)) + 
   geom_bar(colour='black', fill="#33CC00", alpha=.5, 
      size=0, width=.7,stat='identity') + xlab("Deal Funded Date") + 
   ylab("Funded Deal Count") + 
   opts(title="Deals funded since January 2011") + 
   facet_grid(grouptype~fundingstage, scales='free_y') + 
   opts(axis.text.x =theme_text(angle=45, size=5))

这是头

head(funded.agvc)

Answer 1

如果我将stat='identity'更改为stat='sum'，这对我有用（情节有点傻，因为我只使用了上面发布的数据的头部）。我收到有关opt vs theme和theme_text vs element_text的警告，因为我使用的是更新版本的ggplot2 ...

ggplot(data=funded.agvc, aes(moved_date,deal_count)) + 
   geom_bar(colour='black', fill="#33CC00", alpha=.5, 
      size=0, width=.7,stat='sum') + xlab("Deal Funded Date") + 
   ylab("Funded Deal Count") + 
   opts(title="Deals funded since January 2011") + 
   facet_grid(grouptype~fundingstage, scales='free_y') + 
   opts(axis.text.x =theme_text(angle=45, size=5))

使用geom_bar在ggplot2中求和的问题
