22    
23            * DESCRIPTION (LicenseDetails): new; such that 'License:' becomes "canonical"
24

26    
27            * R/diagMatrix.R (subDiag): fix when x[..] became a vector
28

44    2008-02-20  Martin Maechler  <maechler@stat.math.ethz.ch>
45    
46            * R/Matrix.R (Matrix): no longer use coercions to specific classes
47                    (since we are discouraging them in user code).
