Build a page via loop

Is it possible to dynamically build a page using a loop? I've tried the approach below in an 'asis' block, but it doesn't seem to work.

cat(title, ' {data-icon="fa-line-chart"}\n')
cat("=====================================\n")
cat('\n')

for (i in seq_along(fields)) {
  if (i %% col_no != 0) {
    cat("Row\n")
    cat("-------------------------------------\n")
    cat('\n') 
  }

  cat("### ", fields[[i]], "\n")
  cat('\n')

  create_plot(fields[i])
  cat('\n')
}

There's a similar question on Stack Overflow.

No files or tests are named. Reproduce the R loop in issue #80 and compare its generated markdown and plot output with the linked Stack Overflow example; done means establishing whether loop-built pages are supported and recording a confirmed usage pattern or limitation.
