[Rd] S4 generics "missing"

2005-07-15 Thread Martin Maechler
Thank you, Lars, for persisting on this topic of missing S4 generics! [I'm diverting this away from the original bug report; since this is really about future features rather than R bugs.] Unfortunately it's not as easy as you might think. o One reason is the fact that currently it is still

[Rd] documentation for filter() (PR#8010)

Full_Name: Landon Sego Version: 2.1.1 OS: Windows Submission from: (NULL) (128.173.70.25) In the Details section of the documentation for filter(), it says: The convolution filter is 'y[i] = f[1]*x[i+o] + ... + f[p]*x[i+o-p-1]' Correct me if I'm wrong, but I think it should be:

2005-07-15 Thread Prof Brian Ripley
Reading the posting guide would have shown you that R-help was quite inappropriate, so I have moved this to R-devel. allocString does not allocate a character vector, which is what you want to set as an attribute (not a 'string', whatever that is). (It creates a CHARSXP, a type that should not

Just a note to point out that Martin's R implementation of APL's "take" function was pretty neat. Could we preserve it for posterity somewhere in the R distribution? Failing that, it would complement subsums() of the magic package very nicely. best wishes Robin On 15 Jul 2005, at 14:1

We will incorporate a version of this in R-devel and hence 2.2.0. A bit more work needs to be done on printing: whereas the existing three columns are in comparable units, the p values are not and so get printed to silly accuracies (as can be seen in your example). You also need to explain what
