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

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

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]

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
}

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)
library(svIO)
library(svSocket)
library(R2HTML)
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")')

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)
    }
}
