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。它不会帮助你着色，但我从ESS和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

我的大部分个人函数和加载的库都在rfunction中。r脚本

source("c:\\data\\rprojects\\functions\\Rfunctions.r")


.First <- function(){
   cat("\n Rrrr! The statistics program for Pirates !\n\n")

  }

  .Last <- function(){
   cat("\n Rrrr! Avast Ye, YO HO!\n\n")

  }

# Tinn-R: necessary packages

library(utils)
necessary = c('svIDE', 'svIO', 'svSocket', 'R2HTML')
if(!all(necessary %in% installed.packages()[, 'Package']))
  install.packages(c('SciViews', 'R2HTML'), dep = T)

options(IDE = 'C:/Tinn-R/bin/Tinn-R.exe')
options(use.DDE = T)

library(svIDE)

guiDDEInstall()
shell(paste("mkdir C:\\data\\rplots\\plottemp", gsub('-','',Sys.Date()), sep=""))
pldir <- paste("C:\\data\\rplots\\plottemp", gsub('-','',Sys.Date()), sep="")

plot.str <-c('savePlot(paste(pldir,script,"\\BeachSurveyFreq.pdf",sep=""),type="pdf")')

Stephen Turner关于. rprofiles的帖子有几个有用的别名和启动函数。

我发现自己经常使用他的“ht”和“hh”。

#ht==headtail, i.e., show the first and last 10 items of an object
ht <- function(d) rbind(head(d,10),tail(d,10))

# Show the first 5 rows and first 5 columns of a data frame or matrix
hh <- function(d) d[1:5,1:5]

我发现两个函数是非常必要的:首先，当我在几个函数上设置debug()并且我已经解决了错误，所以我想要undebug()所有函数-而不是一个接一个。在这里添加的undebug_all()函数作为接受的答案是最好的。

其次，当我定义了许多函数并正在寻找一个特定的变量名时，很难在ls()的所有结果中找到它，包括函数名。这里发布的lsnofun()函数真的很好。

下面是我发现的两个方便使用窗口的函数。

第一个将\s转换为/。

.repath <- function() {
   cat('Paste windows file path and hit RETURN twice')
   x <- scan(what = "")
   xa <- gsub('\\\\', '/', x)
   writeClipboard(paste(xa, collapse=" "))
   cat('Here\'s your de-windowsified path. (It\'s also on the clipboard.)\n', xa, '\n')
 }

第二个选项在一个新的资源管理器窗口中打开工作目录。

getw <- function() {
    suppressWarnings(shell(paste("explorer",  gsub('/', '\\\\', getwd()))))
}
