我一直在尝试并且未能制作频率直方图。

这是我的数据：

以下是我对每条鱼的追求：

Graph of One Fish

理想情况下，这将在面部网格上编织在一起，这样我就可以将所有鱼展示在一起。

这是我目前的无用尝试：

ggplot(data,aes(x=length))+geom_histogram()+facet_grid(~species)+theme_bw()

我有点困惑。我不确定频率方面是否有效？任何建议将不胜感激。

Answer 1

R，与大多数非古老的编程语言一样，区分大小写。

您的变量名称为＆＃34;长度＆＃34;和＆＃34;物种＆＃34;。你正在调用小写＆＃34;长度＆＃34;和＆＃34;物种＆＃34;。

大写并且它将起作用：

ggplot(data, aes(x=Length)) + geom_histogram() + facet_grid(~Species) + theme_bw()
