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)
    }
}

这是我的。我总是使用主要的cran存储库，并且有代码可以使它很容易地获得开发包中的代码。

.First <- function() {
    library(graphics)
    options("repos" = c(CRAN = "http://cran.r-project.org/"))
    options("device" = "quartz")
}

packages <- list(
  "describedisplay" = "~/ggobi/describedisplay",
  "linval" = "~/ggobi/linval", 

  "ggplot2" =  "~/documents/ggplot/ggplot",
  "qtpaint" =  "~/documents/cranvas/qtpaint", 
  "tourr" =    "~/documents/tour/tourr", 
  "tourrgui" = "~/documents/tour/tourr-gui", 
  "prodplot" = "~/documents/categorical-grammar"
)

l <- function(pkg) {
  pkg <- tolower(deparse(substitute(pkg)))
  if (is.null(packages[[pkg]])) {
    path <- file.path("~/documents", pkg, pkg)
  } else {
    path <- packages[pkg]
  }

  source(file.path(path, "load.r"))  
}

test <- function(path) {
  path <- deparse(substitute(path))
  source(file.path("~/documents", path, path, "test.r"))  
}

我喜欢保存我的R命令历史，并在每次运行R命令时都可用:

在shell或.bashrc中:

export R_HISTFILE=~/.Rhistory

在.Rprofile:

.Last <- function() {
        if (!any(commandArgs()=='--no-readline') && interactive()){
                require(utils)
                try(savehistory(Sys.getenv("R_HISTFILE")))
        }
}

这是我的想法，包括上面提到的一些想法。

你可能需要看两件事:

.set.width() / w()将打印宽度更新为其中一个终端。不幸的是，我没有找到一种方法在终端调整大小上自动做到这一点- R文档提到这是由一些R解释器完成的。 每次都会保存历史记录，并保存时间戳和工作目录

.

.set.width <- function() {
  cols <- as.integer(Sys.getenv("COLUMNS"))
  if (is.na(cols) || cols > 10000 || cols < 10)
    options(width=100)
  options(width=cols)
}

.First <- function() {
  options(digits.secs=3)              # show sub-second time stamps
  options(max.print=1000)             # do not print more than 1000 lines
  options("report" = c(CRAN="http://cran.at.r-project.org"))
  options(prompt="R> ", digits=4, show.signif.stars=FALSE)
}

# aliases
w <- .set.width

.Last <- function() {
  if (!any(commandArgs()=='--no-readline') && interactive()){
    timestamp(,prefix=paste("##------ [",getwd(),"] ",sep=""))
    try(savehistory("~/.Rhistory"))
   }
}

我的不太花哨:

# So the mac gui can find latex
Sys.setenv("PATH" = paste(Sys.getenv("PATH"),"/usr/texbin",sep=":"))

#Use last(x) instead of x[length(x)], works on matrices too
last <- function(x) { tail(x, n = 1) }

#For tikzDevice caching 
options( tikzMetricsDictionary='/Users/cameron/.tikzMetricsDictionary' )

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!: -)
