detransform: Detransform Centered/Scaled Data

Description

This function back transforms centered/scaled data.

Usage

detransform(x_data, ...)

Value

Returns de-centered and de-scaled model matrix.

Arguments

x_data

Model matrix that has been centered and/or scaled.

...

Additional arguments specifying centering/scaling attributes.

Details

The following additional arguments can be passed:

• attr_center : Centering attributes.

  • If none specified, attr(x_data,'scaled:center') is utilized.

• attr_scale : Scaling attributes.

  • If none specified, attr(x_data,'scaled:scale') is utilized.

See Also

• scale for centering and scaling.

• all.equal for testing "near equality".

Examples

# Set seed for reproducibility
set.seed(1964)
# Generate a 10x10 matrix with random numbers
original_data <- matrix(rnorm(100), nrow = 10)
# Scale and center the data
scaled_centered_data <- scale(original_data, center = TRUE,
scale = TRUE)
# Transform the scaled/centered data back to its original form
original_data_recovered <- detransform(scaled_centered_data)
# Compare the original data and the recovered data
all.equal(original_data,original_data_recovered)
