Changes in version 1.3-0 (2026-03-04) - readCEP can return data in "long" format as triplets of row names (typically sites), column names (typically species) and data values. As default, rows with zero or negative values are omitted. - Reports used Fortran compiler (e.g., in 00install.out) per wish of issue #8. Changes in version 1.2-2 (2023-06-25) - Maintenance release to adapt to new settings in R build tools for Fortran. Github issue #7 Changes in version 1.2-1 (2022-03-30) - Maintenance release for new Windows build tools. Fortran binary is now 64-bit in Windows. Changes in version 1.2-0 (2021-01-05) - Installation failed in 'Apple Silicon'. GitHub issue #6 - Can return the data as a sparse matrix (of Matrix package). This can offer considerable saving in disk storage. However, several R functions may be unable to handle sparse matrices, but they must be changed to ordinary dense matrices or data frames. Moreover, sparse matrices are often changed to full dense matrices within the analysis. For instance, a centred or standardized data matrix in ordination is dense. Changes in version 1.1-3 (2019-05-08) - This version depends on R 3.6.0 or later. This is a maintenance release that adapts to internal changes in the build system of R. There are no functional changes in the package, and if the current version works in your system, there is no need to upgrade. Changes in version 1.1-2 (2018-02-05) - This is the first CRAN release.
