Re: [R] Separating variables in read.table
Patrick -
There's no simple way to do what you want, because
R discourages you from having lots of separate
related objects. Instead, you are encouraged to store
your objects in an organized form, such as a list,
data frame or matrix. For your example, I'm assuming
you are using the word "table" to describe a data.frame.
If this is the case , you can refer to the individual
columns of test as
test[,1]
test[,2]
etc.
or
test$x1
test$x2
etc.
or
test[,'x1']
test[,'x2']
Also remember that R has functions that can operate on
each row or column of a matrix or data frame. So if you
wanted the means of each column of test, you could write
apply(test,2,mean)

Is there a simple command to break this table into individual variables without

And so on. .
Many Thank for any assistance.

Dear Patrick,
Perhaps attach might be what you are looking for.
