Prettier printing for matrices and data frames.
Usage
pprint(x, ...)
# S3 method for class 'matrix'
pprint(x, rowdots = NULL, coldots = NULL, digits = NULL, ...)
# S3 method for class 'data.frame'
pprint(x, rowdots = NULL, coldots = NULL, digits = NULL, ...)Arguments
- x
A matrix or data.frame.
- ...
Additional optional arguments. None are used at present.
- rowdots
Integer specifying the row to replace with
...notation. Default is 4.- coldots
Integer specifying the column to replace with
...notation. Default is 4.- digits
The minimum number of significant digits to be printed in values.
Details
For a matrix or data.frame (which are coerced to a matrix via
data.matrix, pprint() will replace all the rows starting from rowdots
up to and including the second-to-last row with a single row filled with
...s. The same is applied to the columns as well. Hence a large matrix
(or data.frame) will be printed in a much more compact form.
Examples
pprint(randn(100, 100))
#> 100 x 100 matrix of doubles:
#>
#> [,1] [,2] [,3] ... [,100]
#> [1,] -0.2060872 -1.1380124 -1.1936412 ... 1.6600532
#> [2,] 0.0191776 -0.5580151 -0.7517233 ... 0.6097109
#> [3,] 0.0295608 1.0525385 1.4558414 ... 1.0163791
#> ... ... ... ... ... ...
#> [100,] 0.1221034 -0.5035929 -0.1454269 ... -0.9218250
pprint(resize(1:100, 10, 10))
