I am working with a dataset where there are 5 possible outcomes (coded 1:5), I would like to create 5 categorical variables (event1...event5). I am using a for loop an if statements, but I have a large dataset( approx 100,000 rows) it takes quite a bit of time, is there a way to speed this up? Here is some sample code of what I am currently doing. test2 <-rep(seq(1:5),2000) event1 <-

Hi, I'm using a loop to extract 2 columns from an array into multiple files. I can use the following to export 3 files, containing column 'ID' with one of the three event columns. > ID<-c("A","B","C","D","E","F") > event1<-c(0,1,0,0,1,0) > event2<-c(1,1,0,1,0,0) > event3<-c(1,0,1,0,1,0) >

Hello all, This may be a simple question to answer, but I'm a little bit stumped with respect to the calculation of the F statistics in nested anovas with unbalanced design in R. In my case, I have 11 vegetation transects (with 1000 10cmx10cm squares), where we estimated shrub cover. We have two different treatments: wildfire (4 transects) and prescribed burning (7 transects) and we want to

Hey Guys, The ForceFeedback from my Microsoft Sidewinder ForceFeedback Wheel doesn't work with Wine. I compiled wine myself and "ac_cv_member_struct_ff_effect_direction=yes" was set in the config.log like it is told here: http://wiki.winehq.org/ForceFeedback I also checked that FF is working with BZFlag under Linux. When i play BZFlag with Wine, the FF-Effects are missing. I

Sorry if this has been covered before, i can''t imagine it hasn''t, but i''ve been unable to find any information on it. Can i pass my own parameters to the onComplete function specified by Ajax.Request ? My basic setup is i have an html element triggering an event (the ajax update). I have additional information encoded into the element about how it should handle

Thank you for your interest. I am running CentOS-7 installed from CentOS-7-x86_64-LiveKDE-1503.iso and later upgraded to CentOS-7.2. The only packages I have installed have been from CentOS and Epel repos. I'm sure

Hello Recently upgraded to Ubuntu 11.04 and not liking unity I swtiched to xubuntu but was perturbed to find my World of Warcraft FPS drop from 36 FPS in Ubuntu 10.10 and Ubuntu 11.04 'ubuntu classic' down to 3/4 FPS xubuntu. Again, to confirm it wasn't anything in the upgrade I made sure that the FPS is as normal in 11.04 when I select 'Ubuntu Classic' when logging in rather

I am trying to use a Guillemot gamepad with PES6 but the buttons are not recognized. In kubuntu system settings I can see my pad, callibrate the joysticks and see the buttons are recognized, but not inside wine (only the joysticks are recognized). I have tried different combinations for the DirectInput entry in the registry but either I have not stumbled upon the correct one or there is another

In barplot for degree distribution x-axis is not seen. See the example below > g = barabasi.game(500, 0.4) > dd1 = degree.distribution(g) > plot(dd1, xlab="degree", ylab = "frequency") whereas barplot doesnot have any x-axis > barplot(dd1, xlab = "degree", ylab = "frequency") Please see the figures attached.

Dear R-helpers, I have run the code below which I expected to make an object called dd1, but that object does not exist. So, in summary, my problem is that my function is meant to make an object (dd1), and it does indeed make that object (I know that the last line of the function prints it out) but then, after the function has run, the object has disappeared. It's late on a Friday so I may

Buenas tardes, He construido la función “myfun” al objeto de considerar aquellas persones que a partir de una determinada fecha de Apertura tienen como mínimo 65 años. Se tiene su fecha de nacimiento, su fecha de inicio en la institución y su fecha de salida de la misma. Doy vueltas al script y no acabo se saber cómo poder aplicar de un modo eficiente las instrucciones “if” ó bien “ifelse”, y me

Hi, I am plotting degree distribution of a graph using the function, library(igraph) dd1 = degree.distribution(G) plot(dd1, xlab = "degree", ylab="frequency") I would like to plot the mean of the distribution as a vertical line in the attached plot. Please let me know how to do this. Thanks, Kumar http://r.789695.n4.nabble.com/file/n3334375/cdata3_dd.png cdata3_dd.png --

Dear All, Suppose I have a program as below: Outside is a loop for simulation (with random generated data), inside there are several sapply()'s (10~100) over the data and something else, but these sapply's have to be sequential. And each sapply do not involve very intensive calculation (a few seconds only). So the outside loop takes minutes to finish one iteration. I guess the better way

I think that there is a bug in the as.POSIXct function on Windows. Here is what I get on Win2000, Pentium III machine in R 1.8.1. > dd1 <- ISOdatetime(2003, 10, 26, 0, 59, 59) > dd2 <- ISOdatetime(2003, 10, 26, 1, 0, 0) > dd2 - dd1 Time difference of 1.000278 hours Now, the 26th of October was the day that change to the standard time occurred, so I suspect that this has

Dear all, I have an xts object , t.xts with 4 columns: "v1" "DD1" "v2" "DD2" and created a data frame : t <- as.data.frame(t.xts) I would like to extract data and create a new data frame for when the values in column DD1 falls between 0 and 30 and extract the corresponding v1 value. How can I do this? Thanks. -- View this message in context:

Hi there, Problem :: When one tries to change one or some of the columns of a data.frame, R makes a copy of the whole data.frame using the '*tmp*' mechanism (this does not happen for components of a list, tracemem( ) on R-2.6.2 says so). Suggested solution :: Store the columns of the data.frame as a list inside of an environment slot of an S4 class, and define the '[',

I am trying to call a funtion within another function and I clearly am misunderstanding what I should do. Below is a simple example. I know lstfun works on its own but I cannot seem to figure out how to get it to work within ukn. Basically I need to create the variable "nts". I have probably missed something simple in the Intro or FAQ. Any help would be much appreciated. EXAMPLE
