similar to: Need help locating the longest series of consecutive numbers in a matrix

I am relatively new to R, so apologize up front for my long question, particularly if there is too much or too little information. I have a large time series data set where each subject's behavior was originally coded on .25s intervals for 3min task. I am trying to determine if the findings are different depending on the coding interval (i.e. Compare .25s to 1s to 5s to 10s). I also need to

Does anybody know a way to determine the longest run of a number in a vector of numbers? For example if I have the following numbers: 0 0 1 1 1 1 0 1 1 0 0 0 1 1; how can I determine that the longest run of 1's = 4 and longest run of 0's = 3? Thanks, Mark

Classification: UNCLASSIFIED Caveats: NONE Thanks for your quick response. The program you mentioned below available from R is based on number of runs (up or down) not based on a longest length of runs of same events. To be more specific, for example, from a series, HHTHTTTTHHH, the number of runs are 5, and the longest length of runs of the same events is 4. I'll check for the website you

Hola Compañeros, Estoy tratando de "contar" utilizando la función tapply y length y obtengo un error que no entiendo. Agradecería su ayuda. Las líneas son las siguientes: UNO <- subset (datos, CRIH2008 == "VERDADERO") dim (UNO) Abund2008 <- tapply (UNO$Cons, list(UNO$Site, UNO$Trat), length, na.rm=T) Y obtengo este error: Error en FUN(X[[1L]], ...) : 2 arguments

Hi all, I have a problem with package installing in Windows, on my PC machine. The end goal is to be able to use the lme() function. Here's what I did so far: > install.packages("lme4") Warning in install.packages("lme4") : argument 'lib' is missing: using 'C:\Users\Angela\Documents/R/win-library/2.9' --- Please select a CRAN mirror for use in this

Gracias chicos por sus opiniones y recomendaciones. Como dice Javier Rubén, justo lo que quiero es que los chicos aprendan bien los fundamentos de un lenguaje de programación orientado a objetos para que no solo copien el script de una librería, corran y ya. Quisiera que comprendieran los beneficios de R en términos de manipulación de sus bases de datos y optimización de procesos a través de los

Hi All! Been quite a few years and lots of water under the bridge but here I am back! I have a customer that has now decided they need a bit more bandwidth over and above their fixed line! They are not in a good area for ADSL because of copper theft and being a bit to far from the closest DSLAM! They have installed a wireless link and I have made certain that put it behind my simple iptables

Hi Everyone, I'm new to programming R and have accomplished my goal, but feel that there is probably a more efficient way of coding this. I'd appreciate any guidance that a more advanced programmer can provide. My goal -- I would like to find the length of the longest word in a string containing many words separated by spaces. How I did it -- I was able to find the length of the
