Rscript ggplot - ggsave 问题
我使用以下代码绘制图形并将其打印为 PDF：
ggplot(agg_data_cl, aes( as.Date(date), avg_entries, color = classification ) ) +
geom_point()
ggsave(file = "output.pdf")
当我在 TextMate 中执行脚本时，效果很好。
但是，当我通过 RScript 从命令行调用它时，出现以下错误：
Error in all.vars(as.formula(.$facets)) :
could not find function "as.formula"
Calls: print ... <Anonymous> -> <Anonymous> -> <Anonymous> -> all.vars
Execution halted
我在 RScrpipt 文件中使用以下标头：
#! /usr/local/bin/Rscript --vanilla --default-packages=utils
有什么想法可能是什么问题吗？
这是我的命令行会话信息：
R version 2.13.1 (2011-07-08)
Platform: x86_64-apple-darwin10.8.0 (64-bit)
locale:
[1] C/UTF-8/C/C/C/C
attached base packages:
[1] grid utils base
other attached packages:
[1] ggplot2_0.8.9 proto_0.3-9.2 reshape_0.8.4 plyr_1.5.2
loaded via a namespace (and not attached):
[1] grDevices_2.13.1 graphics_2.13.1 stats_2.13.1
在 textmate sessionInfo() 中为我提供了更多附加的基础包：
attached base packages:
[1] grid stats graphics grDevices utils datasets methods
[8] base
我不知道为什么会出现这种情况。
I am using the following code to draw a graph and print it to a PDF:
ggplot(agg_data_cl, aes( as.Date(date), avg_entries, color = classification ) ) +
geom_point()
ggsave(file = "output.pdf")
This works fine when I execute the script in TextMate.
But when I call it from the commandline via RScript I get the following error:
Error in all.vars(as.formula(.$facets)) :
could not find function "as.formula"
Calls: print ... <Anonymous> -> <Anonymous> -> <Anonymous> -> all.vars
Execution halted
I use the following header in my RScrpipt file:
#! /usr/local/bin/Rscript --vanilla --default-packages=utils
Any ideas what could be the problem?
Here is my command line session information:
R version 2.13.1 (2011-07-08)
Platform: x86_64-apple-darwin10.8.0 (64-bit)
locale:
[1] C/UTF-8/C/C/C/C
attached base packages:
[1] grid utils base
other attached packages:
[1] ggplot2_0.8.9 proto_0.3-9.2 reshape_0.8.4 plyr_1.5.2
loaded via a namespace (and not attached):
[1] grDevices_2.13.1 graphics_2.13.1 stats_2.13.1
In textmate sessionInfo() gives me more attached base packages:
attached base packages:
[1] grid stats graphics grDevices utils datasets methods
[8] base
I have no idea why this the case.

问题是调用
Rscript时的--vanilla选项。以下是
Rscript --help关于其选项的说明。
--vanilla基本上意味着Rscript在开始执行 R 之前应该忘记所有内容命令，包括一些已安装的软件包。The problem was the
--vanillaoption when callingRscript.Here is what
Rscript --helpsays about its options..and
--vanillabasically means thatRscriptshould forget everything before it starts executing R commands, including some of the installed packages.as.formula位于 stats 包中。不确定为什么它没有被加载，但看看在脚本开头手动包含library(stats)是否可以解决该问题。as.formulais in the stats package. Not sure why it isn't being loaded, but see if manually includinglibrary(stats)at the start of your script fixes the issue.两件事：
1）确保你有库（ggplot2）_in_your_script_
2）确保你 print() 或plot() ggplot 对象。 （请参阅常见问题解答 7.22）在这种情况下，这可能不是问题，因为您正在节省 gg，但这是 Rscript 会话中的点阵或 ggplot 图形的常见问题。
Two things:
1) Make sure you have library(ggplot2) _in_your_script_
2) Make sure you print() or plot() the ggplot object. (See the FAQ 7.22) This may not be the problem in this instance, since you are gg-saving, but it is a common problem with lattice or ggplot graphics from Rscript sessions.
