遍历目录中的文件，并创建变量与文件名

Question

我有一对夫妇的txt文件的目录

dayton1.txt
datton2.txt
...
dakton50.txt

我想用文件名作为名称创建变量并读取相应的文件。我如何在R中做到这一点？

谢谢！

你想要list.files()，看到它的帮助页面?list.files。例如： -

R> getwd() 
[1] "/blah/blah/packages/analogue/analogue/pkg" 
R> list.files() 
[1] "data"   "DESCRIPTION" "DESCRIPTION~" "inst"   "man"   
[6] "NAMESPACE" "NAMESPACE~" "R"   "src"   "tests"  
[11] "vignettes" 
R> list.files("./inst") 
[1] "ChangeLog" "ChangeLog~" "CITATION" "CITATION~" "COPYING" 
[6] "doc"  "THANKS"  "TODO"
