Presumably there's nothing stopping you *writing* LaTeX in comments -- do you want a code editor that will render and display the LaTeX as you write? (Or am I misunderstanding something?)

Hi list, Could someone explain to me why the following result is not a integer? > difftime(strptime("24NOV2004", format="%d%b%Y"), strptime("13MAY2004", >format="%d%b%Y"), units="days") Time difference of 195.0417 days I'm using R2.12.0 on WinXP. Thanks! ...Tao

Does anyone have comments on the new wording here? Suggested: The Title field should be in title case.

Sorry if this has been covered here somewhere in the past, but ... Does anyone know why logical vectors are *silently* recycled, even when they are incommensurate lengths, when doing logical indexing? This is as documented: For ?[?-indexing only: ?i?, ?j?, ?...? can be logical vectors, indicating elements/slices to select. Such vectors are recycled if necessary to match

Hello everyone I have some data of the following type. 100 200 300 400 500 1.1 1.2 1.3 1.4 1.5 600 700 800 900 1000 1.5 1.7 1.9 2.0 2.4 With plot() and points functions I can plot these 4 lines of data. But I dont know how to do it with qplot or ggplot functions. The scenario is something like this: the hundreds should appear on x-axis and the fractional values of y axis. Thanks alot. MEMON

Thanks, that makes sense. I guess if it never worked for integers (or hasn't worked in a long time, at least) then it doesn't need to be fixed/changed ... cheers Ben On 2025-01-08 11:20 a.m., Ivan Krylov wrote: > On Wed, 8 Jan 2025 10:57:47 -0500 > Ben Bolker <bbolker at gmail.com> wrote: > >> I haven't done the archaeology to figure out when this broke/exactly >> what change in the R code base broke it: it happened within the last >> month or so > > binomial() itself exhibits this property even in R-4.2.2 from more than >...

...making these out-of-bounds accesses should be fixed to avoid doing that. That is, I think this is ultimately a bug in the affected packages, but Rcpp could do better in detecting and handling this for client packages (avoiding a segfault).
