I am developing an R package and distribute it under the GPL-2 license by submitting it to CRAN. According to CRAN's Writing R extensions, i am the author and maintainer of the source code.
The R package implements an algorithm which is published in the Journal of the American Statistical Association. I am not the author of the paper and have no affiliation with the authors or the publisher Taylor & Francis group.
Who is the copyright holder i should add in the DESCRIPTION file of the R package?
Does the term 'copyright holder' refer to the person who invented the algorithm and/or the person who wrote the R source code?
