编译RcppArmadillo时遇到问题.这是我尝试安装包时的结果:
> install.packages("RcppArmadillo")

Hmisc library by Frank E Harrell Jr
Type library(help='Hmisc'), ?Overview, or ?Hmisc.Overview')
to see overall documentation.
NOTE:Hmisc no longer redefines [.factor to drop unused levels when
subsetting. To get the old behavior …我得到了一个简单的data.frame(AD0),它有基本的统计值和因子(group):
mean se sd median group
value1 0.725 0.07149951 0.4522026 1 1
value2 0.650 0.07637626 0.4830459 1 2
value3 0.175 0.06084343 0.3848076 0 3
value4 0.375 0.07752171 0.4902903 0 4
我尝试制作一个简单的条形图:
p <- ggplot(AD0, aes(mean,group)) + geom_bar()
但是,我收到消息:"错误:情节中没有图层"这是一件非常简单的事情,我无法理解为什么它不起作用.
如果有人能帮助我,我会很高兴
