R community, I am trying to create an array of the time differences between datapoints for a very large set. For some reason for 4 of the values the difference has been calculated as NA. Looking at the individual points two of them are "1981-03-29 01:40:00" and "1981-03-29 02:00:00" This is the exact same format as the other points that return values of 20 mins as expected.

Hi, For this example: O <- c(0 0 0 2 0 0 2 0) I want to create an array every time O[i] > 0. The array should be in the form; R[j] <- array(-1, dim=c(2,O[i])) i.e. if O[i] > 0 4 times I want 4 R arrays. Does anyone have any suggestions?

Hi, I am using the uniroot function in order to carry out a bivariate Monte Carlo simulation using the logistics model. I have defined the function as: BV.FV <- function(x,y,a,A) (((x^(-a^-1)+y^(-a^-1))^(a-1))*(y^(a-1/a))*(exp(-((1^(-a^-1)+y^(-a^-1))^a)+y^-1)))-A and the procedure is as follows: Randomly generate values of A~(0,1), y0 = -(lnA)^-1 Where: A=Pr{X<xi|Y=yi-1} and a is the

Hi, First of all, I know that not dropping SYN/FIN isn't really a big deal, it just makes no sense. But since it doesn't make any sense, I don't see the reason why not to discard them. I'm running pf on FreeBSD 5.4-RELEASE-p3 and I scrub any traffic. I've read some other posts on google and as far as I can tell, clearly invalid packets (like packets with SYN/RST set) is

Hello I have the following problem : group the lines of a dataframe when no information change (Matricule, Nom, Sexe, DateNaissance, Contrat, Pays) and when the value of Debut of lines i = value Fin of lines i-1 I can obtain it with a do loop. Is it possible to avoid the loop ? The dataframe initial is df1 dput(df1) structure(list(Matricule = c(1L, 1L, 1L, 6L, 6L, 6L, 6L, 6L, 6L, 8L, 8L, 8L,

Hola, Partiendo de un data frame con 2 variables de fecha (inicio y fin): df <- data.frame(inicio = c(as.Date("2016-01-01"), as.Date("2016-02-14")), fin = c(as.Date("2016-02-01"), as.Date("2016-02-29"))) Necesitaría crear 12 nuevas columnas adicionales, una

Hi, I have the following problem (with R 0.61.3 an Linux, and a new and empty workspace) > oldpar<-par() > par(oldpar) Error: attempt to set invalid value for graphics parameter "fin". > oldpar$fin [1] 6.992034 6.990803 but now: > oldpar$fin <- c(6.99,6.99) > par(oldpar) it works. It seems, that if I set oldpar$fin to values greater than listed above

Hi all, I have problems in a dataframe variables types. Look: from a loop function: for(...){ ... dados.fin <- rbind(dados.fin, c(L=j, A=j^2, Nsp=nsps, N=length(amosfin$SP), AmT="am",NAm=nam, AMST=amst)) dados.fin <- rbind(dados.fin, c(L=j, A=j^2,

Buenas tardes, Tengo un data frame denominado “trabajadores”, que cubre desde el 1 de enero de 1997 hasta el 30 junio de 1999, con 3 columnas: Identificador (ID), la fecha de entrada en la empresa (ENT) y la fecha de salida (SAL). Deseo localizar aquellos trabajadores que, durante dicho periodo, NO han llegado a pasar un 31 de diciembre y un 1 de enero seguidos (cambio de año) como asalariados

Hi all, Please a moment to look my source code, this is very similar to example of the documentation. I added FIXED_POINT flag. My source code compile and build but not decode correctly (the error may be in the while). I work with eVC 4.0 and pocket pc 2003. Someone know what is the error? Thanks. Rodrigo. #include "speex.h" #define FRAME_SIZE 160 void CPlayerDlg::OnButton3() {

Hi all, I have a problem when I am encoding (or decoding) stereo audio. With mono data, things are fine and everything works without any problems. When I try to decode stereo data, all I get is a static sound - similar to that of a radio not tuned to any specific station. I wonder what might be wrong? Below is the code, first, of the encoder and next that of the decoder. Any information or

Ned, Thank you very much for the response. Great example following through on the premise. It sounds like I need to have a better understanding of the traffic patterns on my network to know the optimal order for iptables filtering rules. My brief example - Premise: I want to limit outsiders from interfering with LAN client machines. So, I have the following rules regarding forwarding traffic:

Hi all. I'm trying to decode speex using version 1.1.10's libspeex with fixed_point enabled. copied the sample in the manual (1.1.11) with minor revisions. While running the program, encountered this warning: "Packet is larger than allocated buffer : 38" when calling speex_bits_read_from (&bits, cbits, nBytes) then my program terminated unexpectedly with errors (Unhandled

R community, I am trying to write a code that fills in data gaps in a time series. I have no R or statistics background at all but the use of R is proving to be a large portion of my PhD research. So far my code identifies where and the number of new entries required but I do not know how to add additional rows or columns into an array. Any advice on how this can be done? Here is an example:

I am trying to convert an array from numeric values back to date and time format. The code I have used is as follows; for (i in 0:(length(DateTime3)-1)) { DateTime3[i] <- (strptime(start, "%m/%d/%Y %H:%M")+ i*interval) where start <- [1] "1/1/1981 00:00" However the created array (DateTime3) contains [1,] 347156400 347157600 347158800 347160000 347161200 347162400

Dear list, I have a question about the interaction between R code and Latex language trough the Sweave function in the package "utils". What I'm trying to do is to write a report. Contrary to the examples shown in the Sweave Manual in which table already constructed by R are "exported" on Latex files, what I would like to do is to build a table in which I combine text and

hello everybody in this great mailing list , i have some difficulties to follow my code . i solved some problems thanks to Carine Liang , but i still have one problem and i think it is fatal one. when i encode the voice data in a wav file it is decoded without any errors it gives me 84 bytes wav file size for 139 kbytes wav audio data .Naturally i wanted to return my file back to its normal

Hi, I try to make a dataframe in a loop function, but I dont have succeed. The function is something like this: for(i in c(10,12)) { expr for(j in c(1:2) { total <- c(1,2,3,4,5,6,7) nspf <- length(levels(as.factor(total))) fin <- data.frame(L=i,N=nspf) print(fin) } } This print something like this: L N 1 10 7 L N 1 10 7 L N 1 12

Hi, My problem is at the second fread function, fread(&nbBytes, sizeof(int), 1, fin); //the first fread fread(cbits,1, nbBytes, fin);// the second fread. When I'm debugging always nbytes is greater than cbits. This give me a execution error. Thanks.
