将标签添加到带条件的条形图顶部. [英] Add labels to top of barplot with condition.

问题描述

我有一个看起来像这样的条形图:

I have a barplot that looks like this:

我需要将名称添加到栏的顶部.但我只想标记水平 0.5 线以上的名称.

I need to add the names to the top of the bars. But I only wish to label the names that are above the horizontal 0.5 line.

我可以添加如下标签:

 xx <- barplot(....)
 text(xx, data$features, labels=data$features, pos=3, offset=.5)

但这当然会增加所有值.

But this of course adds all values.

xx <- barplot(y)
yy <- y[y>.5]
xx <- xx[y>.5]
text(xx, yy, labels=yy, pos=3, offset=-1)
