certify

certify produces formal landscape PDF certificates with configurable color themes, optional logos, decorative borders, laurels, and corner ornaments. The package is built on grid only, and no LaTeX or Quarto installation is required.

Installation

Install the released version from CRAN:

install.packages("certify")

Or install the development version from GitHub:

# install.packages("remotes")
remotes::install_github("cwimpy/certify")

Usage

library(certify)

make_certificate(
  path          = "jane_doe.pdf",
  recipient     = "Jane A. Doe",
  title         = "Certificate of Achievement",
  award_name    = "Outstanding Student",
  organization  = "University of Somewhere",
  program       = "Bachelor of Arts in Political Science",
  citation      = paste(
    "in recognition of exceptional dedication, scholarship,",
    "and service to the academic community."
  ),
  academic_year = "2025-2026",
  signers       = list(
    list(name = "Alex Chair, Ph.D.", title = "Department Chair")
  )
)

Themes

Three preset palettes are included:

• cert_theme_classic() — navy and gold on parchment (default)
• cert_theme_formal() — black and silver on cream
• cert_theme_warm() — burgundy and gold on warm cream

For full control, build a custom palette with cert_theme():

my_theme <- cert_theme(
  primary      = "#003366",
  primary_dark = "#001f3f",
  accent       = "#c0a062",
  background   = "#fbf8f1"
)

make_certificate(
  path      = "custom.pdf",
  recipient = "Recipient Name",
  theme     = my_theme
)

Two signers, custom logo, custom page size

make_certificate(
  path      = "award.pdf",
  recipient = "Recipient Name",
  title     = "Certificate of Recognition",
  citation  = "in grateful recognition of years of devoted service.",
  signers   = list(
    list(name = "President Name", title = "President"),
    list(name = "Secretary Name", title = "Secretary")
  ),
  logo      = "path/to/your_logo.png",
  width     = 11.69,    # A4 landscape
  height    = 8.27,
  theme     = cert_theme_warm()
)
