问题描述

从为例，我提出的修改是：

  ggplot（plotData，aes（x，y，label = label，group = label））+ 
 geom_text（）+ 
 geom_smooth（aes（group = 1））

会产生：

From Plot vectors of different length with ggplot2, I've got my plot with lines.

ggplot(plotData, aes(x, y, label=label, group=label)) + geom_line() + stat_smooth()

But this smooths one line each. How do I smooth over all data points?

解决方案

ggplot(plotData, aes(x, y, label=label, group=label)) +
    geom_line() +
    geom_smooth(aes(group = 1))

should do it. The idea here is to provide a new group aesthetic so that the fitted smoother is based on all the data, not the group = label aesthetic.

Following the example from @Andrie's Answer the modification I propose would be:

ggplot(plotData, aes(x, y, label=label, group=label)) +
    geom_text() +
    geom_smooth(aes(group = 1))

which would produce:
