ggplot2 在函数或 S4 中使用时产生错误
当在 function 或 S4 中使用 ggplot2 时,我遇到了困难。这是我的没有功能的代码:

与原始版本相比,您在函数中的版本在开头缺少以下两行:
您是否尝试过使用
debug()
逐步执行函数以查找错误源?Your version in the function is missing the following two lines at the very beginning compared to the original version:
Have you experimented with using
debug()
to step through functions to find the source of errors?只需将
label
列添加到数据框中即可。另外,请注意,
aes
中绝对不应该有 $。这应该有效:
Just add a
label
columns to the data frames.Also, note that you should never have a $ inside
aes
.This should work:
如果您希望能够使用 rownames(G),则必须在 ggplot2 调用之外设置 as.data.frame(G) 。
在对 geom_text 的调用中设置 data=as.data.frame(G) 。
You have to set as.data.frame(G) outside of your ggplot2 call if you want to be able to use rownames(G).
Set data=as.data.frame(G) in your call to geom_text.
您为其提供了一个图层,但没有要绘制的数据。将
label=
移动到对 ggplot 的原始调用中,或者提供带有data=
参数的geom_text()
You're providing it with a layer, but no data to plot. Either move
label=
into your original call to ggplot or providegeom_text()
with adata=
argument
