Hi,
How can I evaluate two or more expressions to return two or more columns?
The command is the following:
eval(parse(text=paste("with(bd,",as.character(var$Formula),")",sep="")))
And the expression to evaluate is for example:
eval(expression(with(bd,Var1*100),with(bd,Var2*200)))
The execution is always for the last expression. I can't execute the two
expressions at the same time. It is possible?
Thanks,
Rita.

It is possible?How about something like this with(bd, c(Var1 * 100, Var2 * 200)) _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400 Charlottesville, VA 22904-4400 Parcels: Room 102 Gilmer Hall McCormick Road Charlottesville, VA 22903 Office: B011 +1-434-982-4729 Lab: B019 +1-434-982-4751 Fax: +1-434-982-4766 WWW: http://www.people.virginia.edu/~mk9y/
