I have a data frame containing monthly observations of the 'density' of each US state, recorded in variables named "density.AL", "density.AK", "density.AZ", and so on for all 50 states. The data frame (called d) also contains a variable called "Date" which is encoded as a string in the format "Jan-09", "Feb-09", etc. I also have

I noticed there is a country_select. Is there anything like us_state_select maybe? More specifically - I''m wondering if I manually have to populate an array with all the U.S. state abbreviations so users can select which state they live in while entering their mailing address. -- Posted via http://www.ruby-forum.com/.

Dear list, I have an irregular time series saved and exported as a zoo object. What is the trick to force zoo to ignore the missing dates when reading it back in? Thanks. > str(g) ?zoo? series from 1948-11-02 to 2012-11-06 Data: num [1:14881, 1:8] 1 0 0 0 0 0 0 0 0 0 ... - attr(*, "dimnames")=List of 2 ..$ : NULL ..$ : chr [1:8] "session" "midterm"

Can someone please show me how to smooth time series data that I have in the form of a zoo object? I have a monthly economies series and all I really need is to see a less jagged line when I plot it. If I do something like s <- smooth.spline(d.zoo$Y, spar = 0.2) plot(predict(s,index(d.zoo)), xlab = "Year") # not defined for Date objects and if I do something like

I have a really long functions, and at the end of the function, I am using a if statement to tag certain keywords based on whether they have certain values contained in them. However, the if statement doesn't seem to work. When I had split up the commands into various functions, it worked fine, but I'm not sure what going on now that it's combined into a single function. myfunc

I am downloading time series data from FRED. I have a working download, but I do not want to write out the download for all 50 states likes this: IDRGSP <- read.table('http://research.stlouisfed.org/fred2/data/IDRGSP.txt', skip=11, header=TRUE) IDRGSP$DATE <- as.Date(IDRGSP$DATE, '%Y-%m-%d') IDRGSP$SERIES <- 'IDRGSP' IDRGSP$DESC <- "Real Total Gross

Dear All, I'am looking for examples showing that correlation does not imply causality, the targeted audience consists of undergraduate students (their first year at the university but in the BioMathStat track). All practicals are under R. I was able to extract this from R datasets: ### begin data(sunspots) data(lynx) spots <- window(sunspots, freq = 1, start = 1880, end = 1900) lnx <-

Hi all. A quick question about the checksum error detection routines in ZFS. Surely ZFS can decide about checksum errors in a redundant environment but what about an non-redundant one? We connected a single RAID5 array to a v440 as a NFS server and while doing backups and the like we see the "zpool status -v" checksum error counters increment once in a while. Nevertheless the

Hello, after spending several hours reading archives, I decided to write new post. I successfully set up packet classification, made some basic HTB setup, made some simple graphical representation from HTB statistics data... BUT, I cannot figure out how to refine HTB to get this behaviour: I need that class "p2p" should be the last one to get some link capacity. If I set both RATE

gReetings: I apologize for the non-programming language. I found what seems to be a strange behavior of plot(). The code follows: #_____________________________ N=3030; gn=.04; tn=1:100 n=N/(1+(N-1)*exp(-gn*tn)) N=n*(1-exp(-gn*tn))/(1-n*exp(-gn*tn)) plot(N) #strange plot N N=rep(3030, 100) plot(N) #behaves as expected ________________________________ Windows XP, R 2.4.0. or 2.4.1 Thanks,

Dear all As we wanted to patch one of our iSCSI Solaris servers we had to offline the ZFS submirrors on the clients connected to that server. The devices connected to the second server stayed online so the pools on the clients were still available but in degraded mode. When the server came back up we onlined the devices on the clients an the resilver completed pretty quickly as the

Hello Everyone, I've been playing with an agi script for paging sip phones. page.agi will take all available sip extensions and assign them to the global variable PAGE_GROUP. Allowing the phones to be paged from the dialplan with the new Page cmd. Extensions to be excluded are presented as arguments to the agi. Each time a page is made this agi refreshes the global variable. This works with

Hello! For comparing two non-normally distributed samples, Leech (2002) suggested to report nonparametric effect size indices, such as Vargha & Delaney's A or Cliff's d. I tried to search the R-sites, but could not find related procedures or packages that include nonparametric effect sizes. Thank you for your help! Citation: Leech (2002). A call for greater use of nonparametric

Hi All, I need to be able to make sense from my shorewall logs. I have installed logwatch and it is mailing me reports but the level of detail is just not there.
