Programmatically generating formatted text in R markdown

问题

I am fairly new to R markdown (and R itself). I am using RStudio to create an R Markdown file. I would like to create a report that has several different plots across different time windows, each with accompanying text. Something like this:

for (i in seq(0, max)) {
  # generate some text with markdown formatting including the value of i
}

I know that it is possible to embed R values inline in markdown text. Is there also a way to generate markdown text inline within R code?

回答1:

Probably Pander package is what you are looking for. It support markdown renderings for R objects.

Toy example of printing lines of data frame.

d> m <- mtcars[1:4, 1:6]
d> for (i in 1:4)
+     pander(m[i,], style="rmarkdown")
