#' Plots all effect estimates against p values with each specific variable in the models
#'
#' \code{all_plot2()} generates a panel of scatter plots with effect estimates of all possible models
#' again p values. Each plot includes effect estimates from all models including a specific variable.
#'
#' @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 xlabels \emph{numeric vector} x-axis tick labels. Default is
#' \code{"c(0, 0.001, 0.01, 0.05, 0.2, 0.5, 1)"}
#' @param xlim \emph{vector} of 2 numeric values for x-axis limits. Default is \code{"c(0, 1)"}.
#' @param xlab \emph{Character} string for x-axis name. Default is \code{"P value"}.
#' @param ylim \emph{vector} of 2 numeric values for y-axis limits.
#' @param ylab \emph{Character} string for y-axis name. Default depends on original model types.
#' @param yscale_log \emph{TRUE or FALSE} re-scale y-axis to "log10". Default is \code{"FALSE"}.
#' @param title \emph{Character} title. Default is \code{"NULL"}.
#' @return A \pkg{ggplot2} object: scatter plot
