[Rd] 'aggregate' should preserve level ordering of factors (PR#9666)

Full_Name: Lutz Prechelt Version: 2.4.1 OS: Windows XP Submission from: (NULL) (160.45.111.67) aggregate (from package stats) should preserve the ordering of levels of factors it works on and also their 'ordered' attribute if present. But it does not. Here is an example: ff = facto

[Rd] 'union' does not handle factors while 'intersect' does (PR#9589)

Full_Name: Lutz Prechelt Version: 2.4.1 OS: Windows XP Submission from: (NULL) (160.45.111.67) 'union' ignores the fact if its arguments are factors while all other set operations (intersect, setdiff, setequal, is.element) treat them sensibly. The manpage does not even mention the te

[Rd] rbind.data.frame reacts on levels without factor (PR#9578)

Full_Name: Lutz Prechelt Version: 2.4.1 OS: Windows XP Submission from: (NULL) (160.45.111.67) I stack a number of data.frames using rbind. Each of these dataframes has a column 'authorname', which is a factor and a column author = unclass(authorname) as piecewise pseudonyms. When usin

[Rd] manage R function and data dependencies like 'make'

Dear R-devels, I am looking for a package (or some other infrastructure) for the following situation: I am doing a larger data evaluation. I have several dozen data files and do not want to keep the persistent data in the R workspace (for robustness reasons). I have several dozen R files, some fo

[Rd] R CMD check: checking examples: how to (not) pause execution

e right way to solve this problem? I can hardly believe that there is none (although the examples of 'plot' suggest exactly this: They run through multiple plots in a hurry.) I guess the appropriate approach would be if example() had some kind of single-stepping option? Any hints? Lutz

[Rd] plot.default 'ylim' error message is wrong (PR#8784)

Full_Name: Lutz Prechelt Version: 2.2.1 OS: WinXP SP2 Submission from: (NULL) (130.133.8.114) This command plot(0, 0, xlim=c(3, 5), ylim=c(0, 10, 17)) should complain about 'ylim' (because it has three elements). However, it does in fact (in my german error message at least) comp
