#' A repeated ordinal logistic regression function for plotting

#' Should be combined with "rep_olr()". For bivariate analyses. The confint() function is rather slow, causing the whole function to hang when including many predictors and calculating the ORs with CI.

#' @param meas primary outcome (factor with >2 levels).
|
|
#' @param vars variables in model. Input as c() of columnnames, use dput().
|
|
#' @param dta data frame to pull variables from.
