generate markdown comments within for loop

Question

I am trying to generate an HTML report, using knitr, based on an R script that has for loops. I want to generate markdown comments from the comments within the for loop, bu

Answer 1

One solution that worked for me, is provided by how to create a loop that includes both a code chunk and text with knitr in R. By using Both results='asis' and two spaces in front of \n at the end of each loop.

example:

Without two spaces:

```{r, results='asis'}
headers <- list("We","are","your","friends")
for (i in headers){
  cat("\n##H ", i, "  \n")
  cat("comment",i)
}

Output (html):

As you can see, the comments and headings get messed together

Solution: With two spaces: cat(" \n") at the end of the loop

for (i in headers){
  cat("\n##H ", i, "\n")
  cat("comment",i)
  cat("  \n")# <---------------------------------
}

note: cat(" \n") needs to be at the very end, it does not work even if you plot or calculate something it in the loop.
