This does what I was hoping it would: aggregate(tm[,-1],by=list(tm[,10]),FUN="mean") but I don't know what "tm[,-1]" means (well - the -1 bit anyway. Does it somehow means the whole matrix?

All, I really need some help. I'm putting samba up on a new windows domain called SIERRA. I'm using Samba 3.0.2a on Solaris 8. I'm barely knowledgeable on Windows NetBIOS... but am good with Solaris. The status is that I've got the daemons running and working normally. I have 1 desktop with 1 PDC & 1 BDC in the SIERRA domain. On the desktop, I can see both DC's but

Hi I have configured samba (version 2.2.7a) on Linux 9. Now I am facing a problem like I am able to invoke the swat in the local machine (http://localhost:901 <http://localhost:901/> ), But I am not able to invoke the swat from other machine. Let us consider Localhost name is moon (linux machine) Another machine is mars (Win 2k) I am able to invoke swat from

Just a minor irritation. 1. When I shutdown from the GDM menu, most of the time the screen goes black and none of the "stopping..." messages are visible until just about the time the mounted filesystems are shutdown, about three lines before acpi poweroff. 2. Always when I shutdown from my desktop manager (IceWm in my case), I get all the messages immediately. Once in a blue moon, this

Crontab offers many refined facilities for Western calendaring, but none for traditional Eastern-- lunar-- designations. So for example, if one wants specify regular occurring events on full moons or on new moons, there is no way to do this. Emacs (a text processor!?) accomplishes this. The math for calculating lunar calendaring is already available; mathematical functions are already

I have searched and tried to read before posting but can find nothing to accomplish change Excel dates in double format to R Can someone please help I have a vector of double like this from Excel. 39965.0004549653 and I want to put them in R such that I can display them in any Date and Time format. as.Date does it ALMOST but chops off the fractional seconds. POSIXct doesn't appear to do

I have a matrix with a POSIXct as a numeric in the first column. I would like to create a new matrix that is "grouped by" my chosed time bars. i.e. So I would like to group by hour or day or 5 days, and have all my columns be summed or averaged or counted.. mydata: V1,V2,V3 10:03:13,3.4,1002 10:03:14,5.6,1001 10:05:27,7.2,999 10:05:33,8.2,998 I want to convert this into say 5

i'm thinking about albums like "dark side of the moon" and also live bands (especially live-pa) and DJs where there's a continuous flow from one song to the next... i could use a MKV file with vorbis or mp3 and include a chapter listing [with named chapters], that would allow listening to the whole thing with no skipping between songs. at the same time, a listener can skip

Hello R users, Doing My PhD I collected count data which I believe is zero inflated. I have run a statistical model with lmer and family=poisson and got summary(model)@sigma=1 so I believe there is no overdispertion. I would like to use the fmr function from the 'gnlm' library but I just cannot figure out from the examples in the help page and some forums out there how to convert the lmer

Hi, A number of people have suggested "I read the manuals"... Could someone help me by telling me where the primary start point is please? For example, I am interested in writing functions with variable number of arguments - where should I start to look? "An introduction to R" only show a brief example - with no pointer to where to find further data. I can't do ?xxx

Thank you for the suggestion, Bill. The result is not quite what I would like. Here's sample code for you or anyone else who may be interested: Al1 = c('A','C','C','C') Al2 = c('G','G','G','T') Freq1 = c(0.0078,0.0567,0.9434,0.9908) MAF = c(0.0078,0.0567,0.0566,0.0092) m1 = data.frame(Al1=Al1,

I was just trying to build the shared lib stuff and include it into RC4 of FreeAmp 2.1 today, but I found that the .def file for the vorbis build stuff is missing and therefore no .lib file is generated. Is there a reason for that, or is it just an omission? In any case, I will hold off on the latest and greatest vorbis stuff in FreeAmp until next week.... --ruaok Freezerburn! All else

Given - UTC timestamp - a location (latitude,longitude,elevation) I want to know - the sun angles - the moon angles - the phase of the moon. I looked on CRAN for astronomy, but didn't notice anything that seems to offer what I want. I could try coding these functions myself, but "if you didn't write it you didn't wrong it".

There is also the package solrad that might do some of this. It is more intended for calculating solar radiation, which is probably not what you want, but may do other things you may find helpful. > On Jan 30, 2024, at 5:44?AM, Enrico Schumann <es at enricoschumann.net> wrote: > > On Tue, 30 Jan 2024, Richard O'Keefe writes: > >> Given >> - UTC timestamp
