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")

  }

  napply <- function(names, fn) sapply(names, function(x)
          fn(get(x, pos = pos)))
  names <- ls(pos = pos, pattern = pattern)
  obj.class <- napply(names, function(x) as.character(class(x))[1])
  obj.mode <- napply(names, mode)
  obj.type <- ifelse(is.na(obj.class), obj.mode, obj.class)
  obj.size <- napply(names, object.size) / 10^6 # megabytes

}

这是我的。它不会帮助你着色，但我从ESS和Emacs…

options(prompt="R> ", digits=4, show.signif.stars=FALSE)


options("pdfviewer"="okular")         # on Linux, use okular as the pdf viewer

options(stringsAsFactors=FALSE)

虽然我的. r配置文件中没有这个，因为它可能会破坏我的合作者的代码，但我希望它是默认的。为什么?

1)字符向量使用更少的内存(但只是很少);

2)更重要的是，我们可以避免这样的问题:

> x <- factor(c("a","b","c"))
> x
[1] a b c
Levels: a b c
> x <- c(x, "d")
> x
[1] "1" "2" "3" "d"

and

> x <- factor(c("a","b","c"))
> x[1:2] <- c("c", "d")
Warning message:
In `[<-.factor`(`*tmp*`, 1:2, value = c("c", "d")) :
  invalid factor level, NAs generated

因子在你需要的时候很有用(比如在图中实现排序)，但大多数时候都很麻烦。

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
