How can I make a collapse with glue package using RMarkdown?

Question

I\'ve been trying to automate the results of some df table in latex using the glue and stargazer packages, but I haven\'t had any results (what I want is for the meaning \"^{*}\

Answer 1

I achieved this using the paste0 function as mentioned here and on the recommendation of @stefan but now I would like to automate the same function for n-columns

library(dplyr)
col.nam = c("AIC(n)", "HQ(n)", "SC(n)", "FPE(n)")
tab.out = data.frame(col.nam, X1, X2)

n.tab = tab.out %>%
  mutate(test1 = if_else(tab.out$X1 < tab.out$X2,
                         paste0(X1,"$^{*}$"),
                         paste0(X1)),
         test2 = if_else(tab.out$X2 < tab.out$X1,
                         paste0(X2,"\\textsuperscript{*}"),
                         paste0(X2)))%>%
  select(col.nam, test1, test2)

colnames(n.tab) = c("Parámetros", "Lag 1", "Lag 2")
print(xtable::xtable(n.tab, 
                     header = F, 
                     caption = "asdasdasdasd",
                     label="table:tb1",
                     caption.placement = "top",
                     align="llcc"),
      hline.after = c(-1,0), 
      include.rownames=FALSE, 
      include.colnames = TRUE,
      add.to.row = list(pos = list(nrow(n.tab)),
                        command = paste("\\hline \n",
                            "\\multicolumn{3}{l}{\\footnotesize{$^{*}$Indica el orden de retraso seleccionado}} \\\\",
                            "\\multicolumn{3}{l}{\\footnotesize{\\textit{Elaboración: Los autores}}}",
                            sep = "")), comment=FALSE,
      sanitize.text.function = function(x){x})
