Since both commands accommodate existing functionality while adding significant basic functionality, I though that their addition to the stats package would be a worthwhile consideration.

Dear R Core, working on my dynamic factor modelling package, which requires several subroutines to create and update several system matrices, I come back to the issue of being annoyed by R not supporting multiple assignment out of the box like Matlab, Python and julia. e.g. something like A, C, Q, R = init_matrices(X, Y, Z) would be a great addition to the language. I know there are several

...th(rhs)) stop("length(lhs) not equal to length(rhs)") list2env(`names<-`(rhs, lhs), envir = parent.frame()) invisible() } but as you say, the input needs to be converted to a list, and it calls several R functions, which led me to end up writing `%=%` in C: https://github.com/SebKrantz/collapse/blob/master/src/small_helper.c#L162. This implementation works in the way you describe, i.e. it has separate methods for all the standard vector types, and coerces to list otherwise. That being said, all implementations in packages falls short of being very useful, because R CMD Check it...

...vir = parent.frame()) value[[1]] } You call it as vals(a, b, c) <- 1:3 and it assigns 1 to a, 2 to b, and 3 to c. It doesn't quite do what you want because it requires that a exists already, but b and c don't have to.

Thanks Duncan and Ivan for the careful thoughts.

Does anyone have something like tapply that is extremely fast for matrices when there is a very large number of levels of the grouping variable? I'm referring to, for example, tapply(x, grouping.variable, function.operating.on.submatrix) where x is a matrix and the submatrix is a subset of the rows of x. The grouping variable's length equals the number of rows of x. -- Frank E

I'm completely new at R... I have sinkhole survey data (lat, long, and elevation) and have been trying to plot a rotatable 3d plot for several hours... cannot get it right. Examples I see tend to be grid data (one elevation value per grid cell); however, my data are more random (known elevations at known (but random) x-y positions). Data format is tab separated, i.e.: lat long
