similar to: Using changing names in loop in R

HI, I would like to extract data in a specific way.  For example, the rainfall data 0,0,1.5,0,0, 3,1,2.5,0,0,0,0, 2.3,0,0,0, 2.1,1.4,0,0,0, 3,2,1,0,0,0... data_1: 1.5, 2.3               ( a single nonzero data between zeros data) data_2: 3.1, 2.5, 2.1,1.4   ( two nonzero data between zeros data) data_3: 3,1,2.5, 3,2,1       ( three nonzero data between zeros data) Thank you so much for any

Dear R Users, Is it possible to make file names dependent on a changing variable? For instance. I generate random numbers in a loop and at each iteration I want data to write to file (I do not want to write everything in one file using 'append'): for (i in 1:50){ x<-matrix(runif(100, min=0,max=1),nrow=5,ncol=20) Write(t(x),file="Data_i.txt",ncolumns=5,sep="\t") }

hi all I am using r (2.15.2) in windows 7 32bit I want to execute an external program from r console. the program is a command line program which needs the following format to start C:/Users/.../dssp-2.0.4-win32.exe -i data_1.txt -o data_1.dssp I used the system command as: system ('C:/Users/.../dssp-2.0.4-win32.exe -i

Hi all, I was using grub2 for booting Archlinux x86_64 in my GPT Internal HDD (/dev/sda) then I switched to syslinux/extlinux. It was working fine but suddenly it staring showing "Boot Error" message on screen. I googled for a solution and tried all syslinux versions from 4.04-pre4 down to 4.03-stable but non of them worked. I don't know what suddenly changed caused this

Hi everybody, I would like to delete rows based on duplicate entries in column 3 in the data matrix X (size 60000 x 57). I have tried the unique(x) command as > data <- X[unique(X[,3]),] however, for some reason the command introduces a lot of NA's into the dataset. So, now I'm looking for a function that eliminates rows, if they have duplicate values in column 3. Does anyone

I am trying to plot data with multiple logical and physical groups using R. Below is a sample of the kind of data I am working with and the desired output. We have a jmp script that can do the same thing, but at ~$200 a year the licensing is counterproductive. Thanks for any help. Data input: Loaded from a CSV file. Physical_1 Logical_1 Logical_2 Data_1 Data_2 x Y Z2

Hi: Is there a way we can set up WINBUGS to run 100 simulated datasets on the same model and output results? Or do we have to call in each dataset at a time and repeat the process 100 times manually? Thanks Anamika [[alternative HTML version deleted]]

Hi Rusers, I found sometimes that the same values cannot be judged to be the same in R. Anybody knows the probelm? I think i ignored some minor detail. Thanks. Here is the example. ############ data1<-matrix(data=c(1,1.2,1.3,"3/23/2004",1,1.5,2.3,"3/22/2004",2,0.2,3.3,"4/23/2004",3,1.5,1.3,"5/22/2004"),nrow=4,ncol=4,byrow=TRUE)

Dear R Help, I am trying to fit a nonlinear model for a mean function $\mu(Data_i, \beta)$ for a fixed covariance matrix where $\beta$ and $\mu$ are low- dimensional. More specifically, for fixed variance-covariance matrices $\Sigma_{z=0}$ and $\Sigma_{z=1}$ (according to a binary covariate $Z $), I am trying to minimize: $\sum_{i=1^n} (Y_i-\mu_(Data_i,\beta))' \Sigma_{z=z_i}^{-1} (Y_i-

Hi, I have two columns that contain numbers along with letters (as shown below) and have different lengths. Each entry in the first column is likely to be found in the second column at most once. For each entry of the first column, if that entry is found in the second column, I would like to get the corresponding index. For instance, if the first entry of the first column is 5th entry in the

Daniel, muchas gracias por contestar y tan rápido. Pues puede ser la solución, he hecho el cambio y sigue sin pintarme los puntos -> data_ <- toJSONArray(data_, json = F) map$geoJson( # leafletR::toGeoJSON(data_, # # lat.lon = c('Lat', 'Long'), # dest=output_geofile), data_, onEachFeature =

Hi, I am stuck with creating a conditional categorical variable in R If my dataframe data_2 has 3 variables A,B,C I want to create variable D which would be something like : data_2$D <- ifelse(data_2$A < data_2$B & promotion_ind =="N",1,0), this throws up an error "In Ops.factor(data_2$A,data_2$B) : < not meaningful for factors I have tried converting the

Combining and completing the advice from Greg and Boris the complete solution is two lines: data_2 <- read.csv("excel_data.csv", stringsAsFactors = FALSE) match_list <- match( data_2$data1, data_2$data2 ) The vector match_list will have the matching position when it exists and NA's otherwise. Its length will be the same as the length of data_2$data1. You should get

Hola, Ando un poco desesperado con los mapas interactivos de Rcharts <https://github.com/ramnathv/rCharts>+Leaflet. Estoy intentando pintar en un mapa las cámaras de tráfico de madrid, y las estaciones de calidad del aire, simplemente donde están, es decir, aun no estoy recogiendo los datos de medida.

So im here now b/c im incredibly frustrated. Please consider the following: #Try 1 Data_<-list() Sn<-1:12 for(sn in Sn){ for(i in 1:10){ Data.X <- rnorm(100,0,10) Data_[[paste(sn,i,sep="-")]]<-Data.X } } ##Try 2 Data_<-list() Sn<-1:12 for(sn in Sn){ for(i in 1:10){ Data.X <- rnorm(100,0,10) Data_[[sn]][[i]]<-Data.X } } In Try 1 i am able to append

It's generally a very good idea to examine the structure of data after you have read it in. str(data2) would have shown you that read.csv() turned your strings into factors, and that's why the == operator no longer does what you think it does. use ... data_2 <- read.csv("excel_data.csv", stringsAsFactors = FALSE) ... to turn this off. Also, the %in% operator will achieve

Hola buenas, a veces empleo desde R shells de unix, Existe alguna manera de utilizar estos shelss desde windows o el lenguaje awk. La idea es hacerlo siempre desde R, igual invoncando cygwin desde windows es posible.
