Hi, I'd like to reshape a sparse matrix generated from the Matrix package. I can't seem to do it with the command dim(A) <- c(6,9) which works perfectly with the base package matrices, but with the sparse matrices it errors with Error in dim(A) = c(6, 9) : dim<- : invalid first argument Manipulating the Dim attribute of the sparse Matrix does not produce the desired effect.

...nable" semantic, and your last change would do that too. My alternative should really work - for factors - for "array"s including "matrix" (as the current ifelse() does!) - for "Date", "POSIXct", "ts"(timeseries), "zoo", "sparseVector", "sparseMatrix" (*), or "mpfr", without any special code, but rather by design. *) Currently needs the R-forge version of Matrix, version 1.2-8. A bit less than an hour ago, I have updated the gist with an updated proposal ifelse2() {and the current alternatives that...

All, Martin: Thanks for this and all the other things you are doing to both drive R forward and engage more with the community about things like this. Apologies for missing this discussion the first time it came around and if anything here has already been brought up, but I wonder what exactly you mean when you want recycling behavior. Specifically, based on an unrelated discussion with Henrik

Dear All, Thanks for your help. However, I would like to draw your attention to the following: Actually, I was replicating the Example 2.3, using the dataset "brainsize.txt" given in Section 2.3.3 ("Summarize by group") at page 55, of a famous book "R by Example" written by "Jim Albert and Maria Rizzo" published in Springers (2012) in a Use R! Series. The
