我正在尝试使用plot_grid在包owplot中制作2x2图。我不断收到错误消息：
plot_clone(plot) 中的错误：尝试应用非函数
我不知道如何纠正这个问题。起初我不确定 copplot 是否只能处理 1x2 或 2x1 布局，类似于您在这个小插曲 https://cran.r-project.org/web/packages/cowplot/vignettes/plot_grid.html。因此，按照接近尾声的示例，我尝试保存两对两个，然后使用plot_grid。但每当我运行该函数时，我都会收到相同的错误消息。
我的四个 ggplots 保存为：

我的牛图代码如下：
require(cowplot)
theme_set(theme_cowplot(font_size=12)) # reduce default font size
top_row <- plot_grid(plot.a, plot.b, labels=c("A","B"))
bottom_row <-plot_grid(plot.c, plot.def, labels=c("C","D"))
plot_grid(top_row,bottom_row)
以前有人遇到过并解决过这个问题吗？为了确保所有系统要求正确，我更新到 R 版本 3.3.1，我在 Windows 10 计算机上从 RStudio 运行该版本。
EDIT
您应该能够将此代码复制并粘贴到控制台。这将创建我的四个数据框，将它们保存为 ggplots，并执行plot_grid。当您独立运行这四个 ggplot 时，它们工作得很好。

我不知道你为什么遇到问题。
这是我正在使用的包：
> getRversion()
[1] ‘3.3.1’
> packageVersion("ggplot2")
[1] ‘2.1.0’
> packageVersion("cowplot")
[1] ‘0.6.3’
请注意，在您粘贴的最后一个代码示例中，您编写了require(gglot2)代替require(ggplot2)，这可能可以解释您遇到的一些问题。另外，没有必要要求cowplot and ggplot2分别地，cowplot将加载ggplot2.
