language inconsistency puzzle (in the tradition of Bill V enables (Hi Bill) puzzle "what is x")

placing labels in polygon center ?
Dear all, is there any function to calculate the center of a polygon mass in R? Actually I need to find the best location within polygons to place labels. Thanks for any hint Jens Oehlschl?gel -- COMPUTERBILD 15/03: Premium-e-mail-Dienste im Test\ --------...{{dropped}}

analysis of function dependencies / namespacing
I am going to document a 10.000 lines of R code project. Before reinventing the wheel, has anyone written a function that analyzes dependencies between R functions? I am thinking of output like caller1 calee1 caller1 calee2 caller1 : caller2 calee7 : and I would like to restrict caller and callee to certain positions in the search path. My guess is, that a quick and dirty solution is

ff package: ff objects don't reload completely on NFS drives from a different machine
Try to close the file on the first nfs client before reopening it on the second nfs client. NFS has something called "close-to-open cache consistency". This means that two clients which have the same nfs file open, cannot rely on seeing the updates from the respective other client. If one clients closes, and the other client opens thereafter, it should see the changes. If you want

questions on csv reading
Hi, Is there any official way to determine the colClasses of a data.frame? Why has POSIXct such a strange class structure? Why is colClasses "ordered" not allowed (and doesn't work)? Background ========== I am writing a chunked csv reader that provides the functionality of read.table for large files (in the next version of package ff). In chunked reading, one wants to learn the

matrices and arrays loose dimension after multiplying with scalar (PR#1979)
A matrix or array with one of its dimensions having zero elements looses its dimension after multiplying with scalar. Admittedly this is an extreme case, however it DOES make sense to retain an objects formal structure after multiplying with a scalar, as e.g. a matrix with zero rows IS a legal object in S. BTW, the prototype does retain the dimension. Best Jens Oehlschlägel # replication code

identical calls are not equal !?
Can please someone familiar with the R internals enlighten me on the following strange observation: # this is IDENTICAL as expected identical(substitute(substitute()), substitute(substitute())) # but NOT EQUAL !???? substitute(substitute()) == substitute(substitute()) # I originally found it on t2 <- function(e){ substitute(e) } t2(substitute(x==y, list(y=y)))[1] # I would expect all

What is the most efficient way to assign to PARTS of objects in other frames/environments?
Can please someone familiar with the R internals explain on the following: PR#1434 from r-bugs clarifies that assign("a[1]", x, SomeOtherFrame) or assign("a$a", x, SomeOtherFrame) will NOT assign to an object 'a' in the other frame BUT create a new object called 'a[1]' resp. 'a$a'. This leads to the following question: what is the most

format.factor (PR#11512)
Dear all, differing from the standard behaviour of 'format' the current (2.7.0) 'format.factor' destroys attributes like 'dim' and 'dimnames'. This unfortunately breaks some general code in the new package 'ff' for large file-based data which will support vectors and arrays of atomic and factors. It would be nice if you could include the following fix in
