At the top of src/nmath/qnorm.c it is stated: * Copyright (C) 1998 Ross Ihaka * Copyright (C) 2000--2005 The R Development Core Team * based on AS 111 (C) 1977 Royal Statistical Society * and on AS 241 (C) 1988 Royal Statistical Society
The routine is in fact an f2c'd version of AS241 from StatLib: http://lib.stat.cmu.edu/apstat/241 and http://lib.stat.cmu.edu/apstat/ It seems odd to me that this is re-licensed under GPL and copyright asserted to be held by R Development Core Team. I expect that if I looked further I could find plenty of other routines with a similar heritage. The StatLib page states, "The Royal Statistical Society holds the copyright to these routines, but has given its permission for their distribution provided that no fee is charged." Why does R Development Core Team claim copyright for what appears to be work copyright RSS? You really ought to ascribe the copyright to RSS. I don't think that the GPL is compatible with the StatLib license since the GPL does not forbid charging a fee for distribution. I guess you could come to some agreement with the RSS and I'm sure they would be happy to help. I think that it is important to be very precise on matters of licensing which is why I raise the point.
