专家 R 用户，您的 .Rprofile 中有什么? [英] Expert R users, what's in your .Rprofile?

问题描述

我总是发现其他人的启动配置文件对这门语言既有用又有益.此外，虽然我对 Bash 和 Vim，我对 R 一无所知.

I have always found startup profile files of other people both useful and instructive about the language. Moreover, while I have some customization for Bash and Vim, I have nothing for R.

例如，我一直想要的一件事是窗口终端中输入和输出文本的不同颜色，甚至可能是语法突出显示.

For example, one thing I always wanted is different colors for input and output text in a window terminal, and maybe even syntax highlighting.

推荐答案

这是我的.它不会帮助你着色，但我从 ESS 和 Emacs 那里得到了......

Here is mine. It won't help you with the coloring but I get that from ESS and Emacs...

options("width"=160)                # wide display with multiple monitors
options("digits.secs"=3)            # show sub-second time stamps

r <- getOption("repos")             # hard code the US repo for CRAN
r["CRAN"] <- "http://cran.us.r-project.org"
options(repos = r)
rm(r)

## put something this is your .Rprofile to customize the defaults
setHook(packageEvent("grDevices", "onLoad"),
        function(...) grDevices::X11.options(width=8, height=8, 
                                             xpos=0, pointsize=10, 
                                             #type="nbcairo"))  # Cairo device
                                             #type="cairo"))    # other Cairo dev
                                             type="xlib"))      # old default

## from the AER book by Zeileis and Kleiber
options(prompt="R> ", digits=4, show.signif.stars=FALSE)


options("pdfviewer"="okular")         # on Linux, use okular as the pdf viewer
