I want to import data from about 2000 text files, and hope to create a data frame to make it easy to quote the data. For example, the files like this Oil_20030801.txt, Oil_20030804.txt, Oil_20030805.txt … Oil_20120427.txt The dates aren’t continuous. I want to create the data frame called “Oil”, like that Oil20030801<-read.table(“E:/Oil/ Oil_20030801.txt”) Oil20030804<-read.table(“E:/Oil/ Oil_20030804.txt”) Oil20030805<-read.table(“E:/Oil/ Oil_20030805.txt”) … Oil20120427<-read.table(“E:/Oil/ Oil_20120427.txt”) It is a time consuming way. How can I perform a convenient way? Thank you!
