Hide text inside a regression dataset

Renders text to a binary image, then calls stego_lm_hide to embed it in a regression dataset.

stego_lm_hide_text(
  text,
  family = NULL,
  size = 200,
  coef.det = 0.05,
  p = 5,
  M = 100
)

Arguments

text

family

size

image size in pixels, default 200

coef.det

target R-squared, default 0.05

p

number of predictors, default 5

M

border points per edge, default 100

Value

A data.frame (same as stego_lm_hide)

Examples

if (FALSE) { # \dontrun{
dat <- stego_lm_hide_text("Hello")
