Question

大多数时候我通过远程服务器上的终端处理项目。最近我升级了我的Linux（Debian jessie）平台，然后我无法看到R帮助文件：

$ssh -X abcd
$R
R version 3.3.1 (2016-06-21) -- "Bug in Your Hair"
Copyright (C) 2016 The R Foundation for Statistical Computing

R is a collaborative project with many contributors.
Type 'contributors()' for more information and
'citation()' on how to cite R or R packages in publications.

Type 'demo()' for some demos, 'help()' for on-line help, or
'help.start()' for an HTML browser interface to help.
Type 'q()' to quit R.

> ?table
sh: vimrpager: command not found

有人知道原因并提出一些建议吗？顺便说一下，我在.Rprofile上有这些设置：

# See R documentation on Vim buffer even if asking for help in R Console:
if(Sys.getenv("VIM_PANE") != "")
            options(help_type = "text", pager = vim.pager)
    }
}

options(help_type = "text",
        "width"=200)
#clean workspace everytime when quit R
.last<-function() rm(list=ls())

Answer 1

我们正在＆＃34;泛型＆＃34;我们在## Default browser R_BROWSER=${R_BROWSER-'xdg-open'} ## Default editor EDITOR=${EDITOR-${VISUAL-vi}} ## Default pager PAGER=${PAGER-'/usr/bin/pager'} ## Default PDF viewer R_PDFVIEWER=${R_PDFVIEWER-'/usr/bin/xdg-open'}中使用这些设置查看的内容：

PAGER

由于此处可能使用了/usr/bin/pager，因此您可以检查 apt-cache search pager的当前设置（可能是符号链接）失败并解决的原因。 Task显示了许多替代方案（大量误报）。
