It seems is.weekend() is unsure ? # Start R 1.9.0 with --vanilla on windows xp # load package chron > table(is.weekend(sapply(1:100, function(i){Sys.sleep(0.05);Sys.time()}))) FALSE TRUE 68 32 > date() [1] "Wed May 26 11:18:56 2004" > version _ platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32

Kurt, Uwe suggested I write to you as maintainer of chron ... at the start of is.weekend, in the check on the argument type, maybe just change chron() to as.chron()? This would ensure as.chron.POSIXt gets called on POSIXt arguments, and (I think) fixes the problem. I tested and it seems ok. No warning/error required. > is.weekend function(x) { if(!inherits(x, "dates"))

...7:50:00) (09/03/00 09:20:00) [16] (06/18/00 14:37:00) (09/24/00 15:47:00) (09/03/00 20:38:00) I have checked most of these dates on my calendar and it agrees with the original dataset that they are in fact Sundays. Also, I note that is.weekend() seems to think that Fridays from 2000 onwards are weekends. The dataset contains data from 1996 until early 2001 and chron's is.weekend() resolved dates correctly prior to 2000. From the command line however more recent dates are also resolved correctly. For example I tried: > is.weekend("09/02/01") [1] TRUE and > is.weekend(&q...

Hi, all Here I created a data frame like mydates<- seq(as.Date("2010-05-29"), length = 43, by = "day") myvalues<-runif(43,0,1) myframe<-data.frame(dates=mydates, day=weekdays(dates), value=myvalues) dates day value 1 2010-05-29 Saturday 0.14576143 2 2010-05-30 Sunday 0.37669604 3 2010-05-31 Monday 0.74813943 4 2010-06-01 Tuesday

Hello, Having a boolean *.weekend?* on the Date class would be a good feature. It will basically do this: saturday? || sunday?

Hello, I've been dealing with a set of values that contain time stamps and part of my summary needs to look at just weekend data. In trying to limit the data I've found a large difference in performance in the way I index a data frame. I've constructed a minimal example here to try to explain my observation. is.weekend <- function(x) { tm <-

I''m doing another 0.3.7 release this weekend which will roll in changes from Luis for the win32 service, and some enhancements to the mongrel_rails Unix runner which makes it behave better with switchtower.

I just installed a fresh 3.3 system (because those are the ISO's I had on hand). Upon running yum update, it starts to download headers and then stalls. I hit Ctl-C and it continues to download about 4-5 more headers and stalls. I hit Ctl-C again and it pulls a few more headers. Anyone seen this and/or know how to fix it? TIA Mike

On converting character variables to ordered factors, regression result has strange names. Is it possible to obtain same variable names with and without intercept?

I have a Centos 5.4 machine that has, for the past two weeks, apparently been shut off over the weekend. It's just sitting there turned off on Monday morning and when someone hits the power switch it comes right back on and everything works again. This happened last weekend, and again over this past weekend. Here is /var/log/messages from shortly before it apparently shut down this weekend.

Campers -- In a few weeks there will be a bunch of people in Portland, OR, for a conference. A long time ago some campers mentioned that might be a good time for us to get together and hold a mini CampingConf for a few hours. Is anyone interested? Does anyone want to organize it? I''m thinking Wednesday night, May 16. We could possibly get a spot at FreeGeek (not likely since they are

Incidentally, we're wrapping this up today. If you want to be included in the list of swag-receivers (t-shirt, USB car charger, and stickers), you still have a couple of hours to file a bug and have it verified by the dev team.

Dear All, During the weekend between the hours of 8 am and 5 pm CDT, our IT people will be upgrading the storage infrastructure used by the University of Illinois Computer Science Department. While I do not expect this work to affect any of the LLVM services (those provided by llvm.org or the mailing lists run by the department), I wanted to let everyone know in case our IT people did not
