Print matrix

(a <- 1:3)
#> [1] 1 2 3
(A <- matrix(1:9, nrow = 3))
#>      [,1] [,2] [,3]
#> [1,]    1    4    7
#> [2,]    2    5    8
#> [3,]    3    6    9

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

$(`r a`)^T$

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

library(rmdtool)

Now consider

$`r A`$

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

$$`r A`$$
