#' @title radjust: Replicability Adjusted p-values for Two Independent Studies with Multiple Endpoints
#'
#' @description This package provides the adjusted p-values for the null hypothesis of no replicability across studies for two study designs: a primary and follow-up study, where the features in the follow-up study are selected from the primary study; two independent studies, where the features for replicability are first selected in each study separately. The latter design is the one encountered in typical meta-analysis of two studies, but the inference is for replicability rather than for identifying the features that are nonnull in at least one study.

#' @title p-values of 29 Behavioural Measures in Two Studies
#'
#' @description In different laboratories, the comparison of behaviours of the same two strains of mice may lead to opposite conclusions that are both statistically significant.
#' An explanation may be the different laboratory environment, i.e., personnel, equipment, or measurement techniques,
#' affecting differently the study strains.
#' This data set provides the p-values for testing the association of mice strain with 29 behavioural measures from five commonly used behavioural tests  in
#' two laboratories: the laboratory of H. Wurbel at the University of Giessen, and the laboratory of P. Gass at the  Central Institute of Mental Health, Mannheim.
#' The data table contains two-sided p-values. To transform all the two-sided p-values to one sided in the same direction, see the example in \code{\link{radjust_sym}}.

#' @title p-values of 126 SNPs followed from a primary study to a follow-up study for testing their association
#' with Crohn's disease.
#'
#' @description To discover the associations between SNPs and Crohn's disease, 635547 SNPs were examined in a primary study. For follow-up, 126 SNPs were measured in an independent study.
#' The criteria for follow-up were as follows: the two smallest p-values in each distinct region with primary study p-values below 0.00005.
