[R] passing a vector of variable names to the ... pairlist function argument

by the function, rather than the object names. For example, x1 - 1:4 x2 - 2:5 x3 - 3:6 xs - c(x1, x2, x3) If I wanted to cbind(x1, x2, x3) without typing this out, how would I do it? Thanks very much! Jessica Myers Instructor in Medicine Division of Pharmacoepidemiology Brigham and Women's
