如何在linux shell命令中运行自定义的R函数？

I want to run a self-defined function in the R file with name "run.plot.R" on a remote HPC with linux.

我想在带有linux的远程HPC上的名为“run.plot.R”的R文件中运行自定义函数。

I type the linux command :

我输入linux命令：

R CMD run.plot.R

But it seems the function code is not read by R from the file yet. How can I load the function file into R and then run it?

但似乎R还没有从文件中读取功能代码。如何将函数文件加载到R然后运行它？

#1

Three options are:

有三种选择：

Rscript run.plot.R

要么

R CMD BATCH run.plot.R

or use the littler app, see http://dirk.eddelbuettel.com/code/littler.html

或使用更小的应用程序，请参阅http://dirk.eddelbuettel.com/code/littler.html

All three of these run in a non-interactive mode.

所有这三个都以非交互模式运行。

If you want to run interactively, either

如果您想以交互方式运行，也可以

R --file run.plot.R

or just start R via

或者只是启动R via

then once R is running

一旦R运行

source("run.plot.R")

However, all of the above assumes that run.plot.R contains function code and the R calls to run those R functions.

但是，所有上述假设run.plot.R包含函数代码而R调用运行这些R函数。

Finally, given the filename, whether any plots are or can b generated will depend on how is running on the remote Linux servers, whether X is forwarding over the connection you are using, etc.

最后，给定文件名，是否生成任何绘图将取决于在远程Linux服务器上运行的方式，X是否通过您正在使用的连接进行转发等。

I often use

我经常使用

R --vanilla -f <filename>

The --vanilla flag is used to ensure a consistent R environment among multiple users. Depending on your needs, you may or may not want to use it.

--vanilla标志用于确保多个用户之间的一致R环境。根据您的需要，您可能会也可能不想使用它。
