...awkward to reproduce in my versions and did not seem interesting anyway. Instead, I added an error message if length(n) > 1. - I used the word "scalar" in the aforementioned error message to mean a vector of length 1. Perhaps is this not the correct R terminology? - I added a 'addrownums = TRUE' argument to head() used when n < 0, similar to tail() with n > 0. This required to write separate methods for classes 'data.frame' and 'matrix'. - The 'function' methods are not modified. - In the man page, the 'function' method was not documen...

...* For head(x, n) and tail() the default and other S3 methods notably for _vector_ n, e.g. to get a "corner" of a matrix, has been extended to array's of higher dimension thanks to the patch proposal by Gabe Becker in PR#17652. Consequently, optional argument addrownums is deprecated and replaced by the (more general) argument keepnums. An invalid second argument n now leads to typically more easily readable error messages. * New function .class2() provides the full character vector of class names used for S3 method dispatch. * Printi...
