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)

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

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
}

我有这个，更动态的技巧来使用全终端宽度，它试图从COLUMNS环境变量中读取(在Linux上):

tryCatch(
  {options(
      width = as.integer(Sys.getenv("COLUMNS")))},
  error = function(err) {
    write("Can't get your terminal width. Put ``export COLUMNS'' in your \
           .bashrc. Or something. Setting width to 120 chars",
           stderr());
    options(width=120)}
)

这样，即使您调整终端窗口的大小，R也将使用全宽度。

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"))  
}
