Transposing

Good! Matrices are widely used in math, starting with different geometrical transformations, and ending with neural networks (yes, matrices are commonly used in AI).

What if we have a matrix and want to 'rotate' it? (or vice versa)?

In math, this operation is called transposing. It swaps columns with rows. In R this operation is implemented under t() function. This function receives the matrix you want to transpose as the parameter. For example,

123456
# Initial matrix m <- matrix(1:6, nrow = 2) m # Output initial matrix # Output transposed matrix t(m)
copy

As you can see, the initial matrix was 2x3 (2 rows and 3 columns), and the transposed is 3x2.

Taak

Swipe to start coding

Given the matrix from the previous chapter.

  1. Assign this matrix to the m variable.
  2. Output the transposed m matrix.
