Hi All recently i faced an unknown problem while reading the data. Can someone help me in understanding why this happened. I have .txt file containing X, Y, Z variables. I used the command
Please show at least 2 lines of your data.
a <- read.table("filename", header=TRUE)
Are you sure, that a looks correct? (= have you set the correct seperator in read.table with option sep= ) Best regards, Matthias
after reading the file i am able to view it by tryping a. but i am unable to access the variables in a, by giving the command a$X.
a$X NULL
this is the output it was showing. However the same i am able to access by giving a[[1]]. i tried changing the mode by issuing command a <- as.data.frame(a). But situation remains the same. look forward for experts suggestion on this. rgds snvk
