R in Vim

Do not want to install a plugin such as https://github.com/jalvesaq/Nvim-R, which would also depend on the local configure environment and at least installation. So a simple environment is enough.

Since on G40, the window splitting terminal has not been installed, although it natively supports tabs. The basic requirement is window splitting, which can be done via

• :vsp or ctrl+wv
• ctrl+ws

then one window should be the terminal, so I found https://stackoverflow.com/questions/2782752/how-can-i-open-a-shell-inside-a-vim-window, just :ter, and it will automatically create a new subwindow.

用系统自带的拼音输入法出问题，后来换成了 IBUS-RIME，便解决了。另见 https://blog.hohoweiya.xyz/2021/05/02/back/

set tab length

by default, TAB seems to have 8 spaces, and to be consistent with the common setting, redefine it with 4 spaces, following the instruction in https://stackoverflow.com/questions/1878974/redefine-tab-as-4-spaces

add the following lines into ~/.vimrc

set tabstop=4
set shiftwidth=4
set softtabstop=4
set expandtab
