Private tools for writing R markdown documents

Motivated by StackOverflow, including my own answers

• numbering figures: figure captions, references using knitr and markdown to html
• display matrices: For R Markdown, How do I display a matrix from R variable
• enables equation reference: Rendering problem cross-reference equation in r markdown HTML

Install

Denote that this package is made for private usage, so it might not be comfortable to use.

devtools::install_github("ygeunkim/rmdtool")

Print matrix

(a <- 1:3)
(A <- matrix(1:9, nrow = 3))

In case of vector, we can use the R object in the latex block. In fact, we can express this as vector form.

writeLines("$(`r a`)^T$")

Then we can get $(r a)^T$. Writing matrix, however, is quite annoying. If we do the same for the matrix, we will get $r A$. So we need to add new method for knitr::knit_print().

library(rmdtool)

Now consider

writeLines("$`r A`$")

This inline print method $r A$ gives bmatrix form of the matrix. Also,

writeLines("$$`r A`$$")

$$r A$$
