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()))))
}

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' )

我讨厌每次都输入“头”、“摘要”、“名字”这些完整的单词，所以我用别名。

你可以在你的. rprofile文件中放入别名，但是你必须使用函数的完整路径(例如utils::head)，否则它将无法工作。

# aliases
s <- base::summary
h <- utils::head
n <- base::names

编辑:回答你的问题，你可以使用显色包在终端中有不同的颜色。太酷了!: -)

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?)

sink(file = 'R.log', split=T)

options(scipen=5)

.ls.objects <- function (pos = 1, pattern, order.by = "Size", decreasing=TRUE, head =     TRUE, n = 10) {
  # based on postings by Petr Pikal and David Hinds to the r-help list in 2004
  # modified by: Dirk Eddelbuettel (http://stackoverflow.com/questions/1358003/tricks-to-    manage-the-available-memory-in-an-r-session) 
  # I then gave it a few tweaks (show size as megabytes and use defaults that I like)
  # a data frame of the objects and their associated storage needs.
  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
  obj.dim <- t(napply(names, function(x)
            as.numeric(dim(x))[1:2]))
  vec <- is.na(obj.dim)[, 1] & (obj.type != "function")
  obj.dim[vec, 1] <- napply(names, length)[vec]
  out <- data.frame(obj.type, obj.size, obj.dim)
  names(out) <- c("Type", "Size", "Rows", "Columns")
  out <- out[order(out[[order.by]], decreasing=decreasing), ]
  if (head)
    out <- head(out, n)
  out
}
