Here's what I tried.library(ggplot2)df <- readRDS('data.Rda')ggplot(df) + geom_boxplot()Here's the errorDon't know how to automatically pick scale for object of type data.frame. Defaulting to continuousError: Aesthetics must either be length one, or the same length as the dataProblems:df[, 6:15]I saw the ggplot2 docs for geom_boxplot and realize (from the example) that I need to rearrange my data likecol1 col2h1 0.003719430h1 0.003400540h1 0.003741387h1 0.003870634h1 0.003782963h1 0.003643736h2 0.002975544h2 0.002749373h2 0.002918282h2 0.002884002h2 0.002950711h2 0.002884624...and use something likeggplot(df, aes(factor(col1), col2)) + geom_boxplot()But that is a lot of work. I believe that there must be some way to do this automatically which I'm not able to find. Any help is appreciated. 解决方案 You are right ggplot requires your data to be reshaped, but it isn't that hard using the package reshape2:library(reshape2)df <- melt(df)ggplot(df, aes(x=variable, y=value)) + geom_boxplot() 这篇关于使用ggplot2的R中的Boxplot的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
