我经常需要调用一系列调试调用，取消注释它们可能非常乏味。在SO社区的帮助下，我找到了以下解决方案，并将其插入到我的. rprofile .site中。# BROWSER是为我的Eclipse任务设置的，这样我就可以在任务视图窗口中对浏览器调用有一个概述。

# turn debugging on or off
# place "browser(expr = isTRUE(getOption("debug"))) # BROWSER" in your function
# and turn debugging on or off by bugon() or bugoff()
bugon <- function() options("debug" = TRUE)
bugoff <- function() options("debug" = FALSE) #pun intended

setwd("C://path//to//my//prefered//working//directory")
library("ggplot2")
library("RMySQL")
library("foreign")
answer <- readline("What database would you like to connect to? ")
con <- dbConnect(MySQL(),user="root",password="mypass", dbname=answer)

我用mysql数据库做了很多工作，所以马上连接是天赐良机。我只希望有一种方法可以列出可用的数据库，这样我就不必记住所有不同的名称。

我在个人资料中设置了格子颜色主题。以下是我使用的另外两个调整方法:

# Display working directory in the titlebar
# Note: This causes demo(graphics) to fail
utils::setWindowTitle(base::getwd())
utils::assignInNamespace("setwd",function(dir)   {.Internal(setwd(dir));setWindowTitle(base::getwd())},"base")

# Don't print more than 1000 lines
options(max.print=2000)

这是我的。没什么太创新的。为什么要选择特定的选项:

I went with setting a default for stringsAsFactors because I find it extremely draining to pass it as an argument each time I read a CSV in. That said, it has already caused me some minor vexation when using code written on my usual computer on a computer which did not have my .Rprofile. I'm keeping it, though, as the troubles it has caused pale in comparison to the troubles not having it set everyday used to cause. If you don't load the utils package before options(error=recover), it cannot find recover when placed inside an interactive() block. I used .db for my dropbox setting rather than options(dropbox=...) because I use it all the time inside file.path and it saves much typing. The leading . keeps it from appearing with ls().

话不多说:

if(interactive()) {
    options(stringsAsFactors=FALSE)
    options(max.print=50)
    options(repos="http://cran.mirrors.hoobly.com")
}

.db <- "~/Dropbox"
# `=` <- function(...) stop("Assignment by = disabled, use <- instead")
options(BingMapsKey="blahblahblah") # Used by taRifx.geo::geocode()

.First <- function() {
    if(interactive()) {
        require(functional)
        require(taRifx)
        require(taRifx.geo)
        require(ggplot2)
        require(foreign)
        require(R.utils)
        require(stringr)
        require(reshape2)
        require(devtools)
        require(codetools)
        require(testthat)
        require(utils)
        options(error=recover)
    }
}

我讨厌每次都输入“头”、“摘要”、“名字”这些完整的单词，所以我用别名。

你可以在你的. rprofile文件中放入别名，但是你必须使用函数的完整路径(例如utils::head)，否则它将无法工作。

# aliases
s <- base::summary
h <- utils::head
n <- base::names

编辑:回答你的问题，你可以使用显色包在终端中有不同的颜色。太酷了!: -)

下面是将表导出到LaTeX的一小段代码。它将我编写的许多报告的所有列名更改为数学模式。我的. r配置文件的其余部分是相当标准的，上面已经介绍了大部分内容。

# Puts $dollar signs in front and behind all column names col_{sub} -> $col_{sub}$

amscols<-function(x){
    colnames(x) <- paste("$", colnames(x), "$", sep = "")
    x
}
