similar to: pulling recessions out of a hydrograph

The small bit of script below is an example of what I'm attempting to do - find the day on which the 'center of mass' occurs. In case that is the wrong term, I'd like to know the day that essentially cuts the area under the curve in to two equal parts: set.seed(4004) Date <- seq(as.Date('2000-09-01'), as.Date('2000-09-30'), by='day') hyd <-

Hi all, This isn't meant to be a troll. It's a legitimate question asked because I haven't done much with Samba for 9 years. Is there anything Samba can contribute to an all-Linux environment with no Windows or Mac computers?

Hi all, After I converted my Linux desktop from Mandriva 2008.1 with Samba 3.0.28a to Ubuntu 9.04 with Samba 3.3.2, my Windows 98 box could no longer connect to my Linux desktop via Samba. The symptom was that Windows kept asking for the IPC$ password. Linux clients have no problem with the Ubuntu Samba server. My machine is called "mydesk", and on every Linux box in the house, the

Eric B's response provided just the kind of quick & simple solution I was hoping for (appears as the function com below). However, I once again failed to take advantage of the power of R and have reverted back to using a for loop for the next step of the processing. The example below (which requires the library EGRET for pulling an example dataset) works, but probably can be replaced

The Bordeaux Technology Group is proud to announce a 50% off recession busting sale on Bordeaux for Linux, Mac, FreeBSD, PCBSD and OpenIndiana. With the current US unemployment rate hovering near 10% and rumors of the possibility of a double dip recession. We want to do our part to help save individuals and small business as much money as we can on their Wine related software needs. With

Hi Eric, the following works for me. HTH, Eric library(EGRET) StartDate <- "1990-10-01" EndDate <- "2017-09-30" siteNumber <- "10310000" QParameterCd <- "00060" Daily <- readNWISDaily(siteNumber, QParameterCd, StartDate, EndDate) # Define 'center of mass' function com <- function(x) { match(TRUE, cumsum(x/sum(x)) > 0.5) -

Dear List, One persistent feedback I am getting to people who are newly introduced to R ( especially in this cost cutting recession) is - 1) The website looks a bit old. While the current website does have a lot of hard work behind it, should n't a world class statistics package have a better website instead. You can check out www.knime.org which is an open source software , and free, and

Folks, Are there updated instructions on how to set up PXE boot under CentOS 5.x? I found that the system-config-netboot RPM has been absent, and the instructions written reference it, with a bug report not yet closed on Red Hat.

I would like to add vertical shaded blocks in plot.xts graphs (like recession periods in FRED graphs) The reason I use plot.xts instead of plot.zoo is that I like the fact that the grid is automatically aligned with major ticks in plot.xts. xblocks() and rect() do not seem to work with plot.xts (only with plot.zoo). Are there any alternative methods that work with plot.xts? Thanks. -- View

My wife just got laid off - the recession has hit her law firm hard. This means my priorities have shifted to either finding more paying work myself or helping her find another job. This means the timeframe for a finished repo conversion just got more uncertain, as I may not be able to work steadily on it for a while. -- <a href="http://www.catb.org/~esr/">Eric S.

Hello: I've come to a dead-end in my search for a solution to a graphing problem that I am encountering. I have used xyplot (from the lattice package) successfully to plot 36 time-series plots (lines) of under-5 mortality for a set of countries in Sub-Sarahan Africa. What I would now like to do is to add vertical bands (rectangles) that correspond to time-periods during which each of the 36

The impression I get from the list and the references I've perused is that nlme is being phased out in favor of lme4, but lme4 still doesn't have a complete feature set yet. What I'm still fuzzy on, being a relative R newbie, is: (a) what features in nlme are currently missing in lme4 (b) what's the projected time frame on getting them implemented. If anyone can answer my naive

I am new to the world of R/programming so this may be a really easy question. I thank you for your patience and help in advance I would like the characters km^2 to be displayed on the plot subtitle as km squared - two as a superscript. I would also like to have the numbers from the data set for longitude and latitude to be rounded to four decimal places. Thank you. plot (

Dear "R-listers" I've been trying to figure out how to annotate charts in ggplot (ie add text to line charts, highlighted boxes etc). By and large, I can get close to what i want with base graphics, but would ideally like to use ggplot whenever possible (additionally, i would like to add text labels automatically to the chart). The code is below I suspect I need to use geom_rect,

hello all, I am a beginner at R and not exactly a statistician either. I'm messing around with a probit model on an enconomic time series. I can get the model estimated but I have not been able to get it to give me predictions out of sample data. I'm using the predict function but getting errors. Here is my code: #predict a recession 12 months out #k=12 means 12 months forward #dates

Heh, Your sentiments on the website very much mirror my own, although I?m more focused on server applications rather than on desktop (we use Macs and Ubuntu for that). When Red Hat announced Streams, I was terrified at first and my first instinct was to switch to Rocky or a similar 1:1 distro, but then thought there might be something good coming out of the whole ordeal. And indeed it did, we

Hi all, i'm sure there is an easy way to do this, but i'm stumped, so any help would be appreciated. i have a single column of data for precipitation every 15 minutes over a year. i want to sum the precip to daily data. so the first 96 records = the first day, the second 96 records = the second day, and so on.... is there a way to write a for loop that would sum the data to daily, and

I recently upgraded wine from 0.9.7 to 0.9.12 and while checking out that things were working I started up Google Earth but had the following error in terminal: Message from syslogd@TheVoid at Sun May 7 02:40:26 2006 ...
