具体点说,我在《the art of R programming》chapter1用到了这条语句,
examsquiz<-read.table("ExamsQuiz.txt",header=FALSE)
我现在下好了数据,在压缩包里有一个ch1文件夹,里面有这些文件:R workspace, oddcount.R, xh(PDF), z.R , z.Rout. 我要具体怎么操作,才能在数据和程序中建立一个连接呢?现在直接运行这条程序,显示仍是
“Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :
cannot open file 'ExamsQuiz.txt': No such file or directory
