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
}

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' )

让data.frames的显示有点像'head'，只是不需要输入'head'

print.data.frame <- function(df) {
   if (nrow(df) > 10) {
      base::print.data.frame(head(df, 5))
      cat("----\n")
      base::print.data.frame(tail(df, 5))
   } else {
      base::print.data.frame(df)
   }
}

(从如何使'头'自动应用到输出?)

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。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"))  
}
