121    
122            * src/chm_common.c: coerce logical <-> double instead of

131    
132            * R/AllClass.R ("nMatrix"): and subclasses for "nonzero pattern"

207            * R/Auxiliaries.R (asTuniq): new; also make use of R 2.4.x print(*,max)
208    
209    2006-08-30  Martin Maechler  <maechler@stat.math.ethz.ch>
210    
211            * R/dgCMatrix.R: aargh: "Arith(<dgC>, numeric)" was wrong because
212            of a 0-index which was used as 1-index (..hmm)
213    
214            * R/sparseMatrix.R (prSpMatrix): fix printing an all-0 sparse Matrix
215    
216            * R/Auxiliaries.R (all0, is0): for 0-testing in presence of NA's
