Charles Sanders Peirce (1839–1914) is known for his pragmatism framework and sign theory that led to accountability in science and language. In my work, I employed Peirce’s sign theory by focusing on both the theoretical and classification discussions. Using his framework, I analyze different visualization formats and built an R package titled to his name.

Here is my work:
