Using an R markdown file

Generate the pipeline outputs

library(wreportr)

rmd_file = tempfile(fileext = "example3.rmd")
main_dir = paste0(dirname(rmd_file), "/")
dir.create(main_dir)
write.csv(mtcars, file = paste0(main_dir, "alldata.csv"))
vars = t(utils::combn(x = colnames(mtcars)[1:3], m = 2))
for(i in 1:nrow(vars)){
  step_dir = paste0(main_dir, paste0(vars[i, ], collapse = "-"), "/")
  dir.create(step_dir)
  pdf(paste0(step_dir, "aplot.pdf")); plot(mtcars[, vars[i, ]]); dev.off()
  write.csv(mtcars[, vars[i, ]], file = paste0(step_dir, "atable.csv"))
}

Create the Report object

my_steps = list(
  metadata = list(table = paste0("'", main_dir, "alldata.csv'"))
)
for(i in 1:nrow(vars)){
  my_steps[[i + 1]] = paste0(main_dir, paste0(vars[i, ], collapse = "-"), "/")
}
# You can even add text as if you're dealing with latex
my_steps[[2]] <- list(my_steps[[2]], title = "$\\checkmark$ Critical result")

reportr = create_wsteps(my_steps)
reportr = reportr_set_titles(reportr)
report_render(reportr, output_file = "~/Documents/example3")
