 \usage{
-ggstats_add_xy(table_stat, table, group, y="max", bracket.offset=0.05, bracket.inspace=0.05)
+ggstats_add_xy(table_stat, table, group, xcol=NULL, y="max", bracket.offset=0.05, bracket.inspace=0.05, exclude_group=NULL)
 }
 \arguments{
   \item{table_stat}{A table generated by a rstatix funcion such as t_test() or wilcox_test().}
   \item{table}{The original table that was introduced to ggplot.}
   \item{group}{The grouping variable.}
+  \item{group}{The X-axis variable. If null (the default), the function will pick the first column. This is intended when exclude_group is null.}
   \item{y}{The algorithm used to calculate the y height. Is useful to adapt to plots that show all events, bars with the mean, etc... Options are "max" (default), "mean", "mean+sd", "mean+sem".}
   \item{bracket.offset}{Increasing this parameter incresases the y position of the brackets.}
-  \item{bracket.inspace}{Incresaing this parameter increases the space between brackets.}
+  \item{bracket.inspace}{Increasing this parameter increases the space between brackets.}
+  \item{exclude_group}{Variable(s) that will not be grouped. This aims to preserve the variable in order to facet.}

 Generates a table with the coordinates that is required by the ggpubr function "stat_pvalue_manual".
