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

> a <- read.table("filename", header=TRUE)
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.
