Defines functions JS.uniLR_m

Documented in JS.uniLR_m

#' A complete table for multiple univariable survival analysis by using log rank test
#'JS.uniLR_m output the table with general multivariable survival analysis result with Number of total patients,
#'Number of Events, Estimited Survival,P value. This function only change the format of the output table.        
#'@param D A data.frame in which to interpret the variables 
#'@param Event The status indicator, normally 0=alive, 1=dead
#'@param Stime This is the follow up time
#'@param Svars A vector of variables 
#'@param groupns A text vector of the the group names for output 
#'@param month Time for estimiated survival in month
#'@param Rho a scalar parameter that controls the type of test. With 'rho = 0' this is the log-rank or Mantel-Haenszel test, and with 'rho = 1' it is equivalent to the Peto & Peto modification of the Gehan-Wilcoxon test.
#'@return A dataframe of log rank test output including Number of total patients, Number of Events, Estimated Survival ,P values
#'Event   <- c("pd_censor")
#'Stime   <- c("pd_surv")
#'Svars   <- c("tr_group", "age_m")
#'Groupns <- c("Treatment", "Age")
