Print (abbreviated) matrix

This function prints a (possibly abbreviated) matrix.

Usage

print_matrix(
  x,
  rowdots = 4,
  coldots = 4,
  digits = 2,
  label = NULL,
  simplify = FALSE,
  details = !simplify
)

Arguments

x

[atomic() | matrix]
The object to be printed.

rowdots

[integer(1)]
The row number which is replaced by ....

coldots

[integer(1)]
The column number which is replaced by ....

digits

[integer(1)]
The number of printed decimal places if input x is numeric.

label

[character(1)]
A label for x. Only printed if simplify = FALSE.

simplify

[logical(1)]
Simplify the output?

details

[logical(1)]
Print the type and dimension of x?

Value

Invisibly returns x.

Examples

print_matrix(x = 1, label = "single numeric")
#> single numeric : 1
print_matrix(x = LETTERS[1:26], label = "letters")
#> letters : character vector of length 26 
#> A B C ... Z
print_matrix(x = 1:3, coldots = 2)
#> double vector of length 3 
#> 1 ... 3
print_matrix(x = matrix(rnorm(99), ncol = 1), label = "single column matrix")
#> single column matrix : 99 x 1 matrix of doubles 
#>        [,1]
#> [1,]  -2.41
#> [2,]   1.35
#> [3,]   0.42
#> ...     ...
#> [99,]  0.25
print_matrix(x = matrix(1:100, nrow = 1), label = "single row matrix")
#> single row matrix : 1 x 100 matrix of doubles 
#>      [,1] [,2] [,3] ... [,100]
#> [1,]    1    2    3 ...    100
print_matrix(x = matrix(LETTERS[1:24], ncol = 6), label = "big matrix")
#> big matrix : 4 x 6 matrix of characters 
#>      [,1] [,2] [,3] ... [,6]
#> [1,]    A    E    I ...    U
#> [2,]    B    F    J ...    V
#> [3,]    C    G    K ...    W
#> [4,]    D    H    L ...    X
