[R] Help with function and survey data

[Bert Gunter]

1. This is a plain text list. Set your email to post in plain text, not
html, which often gets mangled (see below).

2. I did not run your example, but try:
my_funca(mk =names(dat)[1:9], y = dat$seg_2)

## seg_2 is a component of dat and is not in the environment of the call. I
did not see any data argument that would tell it to look elsewhere, but I
am not familiar with tidy_whatever's nonstandard evaluation conventions.
