#' Draws scatter plot with all effect estimates against AIC
#'
#' \code{all_plot_aic()} generates a scatter plot with all effect estimates against AIC.
#'
#' @export
#' @param data \emph{Object} from \code{all_cox}, \code{all_glm}, \code{all_speedglm}, or \code{all_glm}, including all effect estimate values.
#' @param xlab \emph{Character} string for x-axis name. Default is \code{"AIC"}
#' @param ylab \emph{Character} string for y-axis name. Default depends on original model types.
#' @param title \emph{Character} for plot title. Default is \code{"NULL"}.
#' @return A \pkg{ggplot2} object: scatter plot
#' @examples
#' vlist <- c("Age", "Sex", "Married", "BMI", "Education", "Income")
#' results <- all_cox(crude = "Surv(t0, t1, Endpoint) ~ Diabetes", xlist = vlist, data = diab_df)
