m {matricks}

A shortcut to create matrix defining rows

Description

One of the main functionalities of the package. It is an alternative to standard way we define matrices in R.

Usage

m(...)

Arguments

...

Single values, vectors, matrices and '|' as special symbol which breaks input on the rows.

Value

matrix with defines elements

Examples

# Typically, we define matrices like this:
x <- matrix(c(1, 2, 3,
              4, 5, 6,
              7, 8, 9), nrow=3, byrow=TRUE)
x
# However, this way of ceating matices seems to be
# a little bit clunky. Using `matricks`, we can do
# it in more staightforward way dividing our input
# into rows by using special symbol `|`
x <- m(1, 2, 3|
       4, 5, 6|
       7, 8, 9)
x
# Moreover, we can pass to the `m` function
# whole sequences or even matrices.
x <- m(1:5 | 6:10 | 11:15 )
x
# We can combine multiple matrices into one
m(diag(3),     diag(3) * 3|
  diag(3) * 3, diag(3)    )
