前言

在生物信息學(xué)數(shù)據(jù)分析中，R語言是一個(gè)不可或缺的工具。為了提高R語言編程效率，合理設(shè)置快捷鍵顯得尤為重要。本文介紹在VSCode Windsurf Cursor 中一些實(shí)用的R語言快捷鍵設(shè)置，讓非 Rstudio 的 IDE 用起來得心應(yīng)手😑

操作種類

管道操作符

• 管道操作符：%>% ，這是來自tidyverse包的經(jīng)典管道操作符，用于鏈?zhǔn)綌?shù)據(jù)處理，使代碼更清晰易讀。舉個(gè)例子：data %>% filter() %>% select()
• 新型管道操作符： %<>%，來自magrittr包的復(fù)合賦值管道操作符，可以同時(shí)完成管道操作和賦值。例如：data %<>% filter() %>% select()

賦值操作符

• 左箭頭賦值：<-，R語言中最常用的賦值方式
• 右箭頭賦值：->，反向賦值操作符

例子：x <- 1; 1 -> x

集合相關(guān)操作

• 成員判斷操作符：%in%，用于判斷元素是否存在于向量或列表中,例如："gene1" %in% gene_list

其他

• RMarkdown相關(guān)，插入R代碼塊，快速在Rmd文件中插入R代碼塊，
• R 選項(xiàng)設(shè)置快捷鍵，常用選項(xiàng)設(shè)置，快速設(shè)置R環(huán)境的常用選項(xiàng)，比如：最大打印行數(shù)：100，啟用httpgd圖形設(shè)備，繪圖設(shè)備為quartz等。

配置方法

所有快捷鍵都在R文件(.r)和RMarkdown文件(.rmd)中生效。快捷鍵設(shè)置可以根據(jù)個(gè)人習(xí)慣進(jìn)行自定義修改?？梢钥焖購?Rstudio 向其他 IDE 遷移，這些設(shè)置將幫在進(jìn)行生物信息學(xué)分析時(shí)更高效地編寫R代碼

打開 VSCode Windsurf Cursor 等的用戶設(shè)置Json文件，添加：
