To reference or cite the objects present in the Software Heritage archive, permalinks based on SoftWare Heritage persistent IDentifiers (SWHIDs) must be used instead of copying and pasting the url from the address bar of the browser (as there is no guarantee the current URI scheme will remain the same over time).
Select below a type of object currently browsed in order to display its associated SWHID and permalink.
All R code and documentation in this package (fields) is licensed under the terms of the GPL license. NOTE: The sparse matrix methods used in fields are supported by the package spam and there are a subset of fortran routines in spam where some licensing issues are unclear. Please refer to the spam license information for details. Note that many functions in fields e.g. Tps, Krig, all the graphical functions, do not require this package so much of fields will be functional under a GPL license.
