Hi. I have a matrix stored in a large, tab-delimited flat file. The first row contains column names. Because the matrix is symmetric, the file has lower triangular format, so the second row contains one number, the third row two numbers, etc. In general, row k+1 contains k numbers; the matrix has 3000 rows, so the file has 3001 rows. The file has variable length records, so each row ends

Hello, Using the svyplot () function, I have plotted four graphs that are saved in four different .png files. I am looking for examples how to redraw the same four graphs within grid viewports so that they stay together on a page. The goal is to create one .png file that will include all four graphs (2 rows, 2 columns). Any help would be appreciated. Thanks, Pradip Pradip K. Muhuri,

Hello, Although my R code for the svymean () and svyquantile () functions works fine, I am stuck with the svyby () and make.formula () functions. I got the following error messages. - Error: object of type 'closure' is not subsettable # svyby () - Error in xx[[1]] : subscript out of bounds # make.formula () A reproducible example is appended below. I would appreciate if

Hi, I?m trying to figure out how to put images into my package?s help documentation. I?ve gotten to the point where I can put the images in the /inst/doc/ directory. I have also gotten to the point where I have package checks without any warnings. I couldn?t find the terms ?picture,? ?image,? or ?graphic? in a text search within the Writing R Extensions: 2 Writing R documentation files

Hello, I would like to learn how to set up Github/repository and upload/update files and am looking for "Github for Dummies". Any help will be appreciated. Thanks, Pradip

Hi Everyone, I am a new R user and trying to run R jobs in batch mode. Robert Muenchen (2009), in his book "R for SAS and SPSS Users", has suggested writing a small batch file like mR.bat as shown below: "C:\Program File\R\R-2.10.0\bin\Rterm.exe" --no-restore --no-save < %1 > %1.Rout 2>& 1 Could anyone tell me in which directory or subdirectory I should

Hi Can anybody please suggest me about the documentation of "factanal.fit.mle()" (Not factanal()------ searching factanal.fit.mle() in R always leads to factanal()). Is there any function for doing principal component factor analysis in R. Regards Souvik Bandyopadhyay JRF, Dept Of Statistics Calcutta University [[alternative HTML version deleted]]

Dear all I have to combine 3D netCDF files (lon, lat, time). The files contain data of one month and I need a year file containing all the data. Because the attributes of all files are the same, I copied the first file and appended the data of the other months. This went well until the provider of the data changed the time-dimension from UNLIMITED to LIMITED. Is there a way to change the time

Greetings, R-Wizards: I'm trying to find an extremum subject to a nonlinear constraint. (Yes, I have perused the archives but have found nothing positive.) The details of the problem are these: In a paper published some years ago in Technometrics, ("Confidence bands for cumulative distribution functions of continuous random variables" Technometrics, 25, 77-86. 1983), Cheng and

I've written a function that takes some input data output from a simulation model and creates some graphs. It's not very complicated code, and it works perfectly fine if I just run the code as is. But I have converted it into a function so we call it externally, and when I try to source the code to test the function, I get the error message "variable names are limited to 256

Hi, I am trying to figure a way to allocate a string SEXP so that gc() won't ever collect it. Here is a little bit of a background. Suppose I want to write a .Call-callable function that upon each call returns the same value, say mkChar("foo"): SEXP getFoo() { return mkChar("foo"); } The above implementation doesn't take advantage of the fact that

Dear R-help, Could someone please try to explain this paradox to me? What is more likely to show up first in a string of coin tosses, "Heads then Tails", or "Heads then Heads"? ##generate 2500 strings of random coin flips ht <- replicate(2500, paste(sample(c("H", "T"), 100, replace = TRUE), collapse =

Hello List, My goal is to create a 5 category variable (p1_st_data$ob_mrj_cat), based on the p1_st_data$obt_mrj_p variable, using the following code for 50 States and District of Columbia (N=51). p1_st_data$ob_mrj_cat <- cut (p1_st_data$obt_mrj_p, quantile (p1_st_data$obt_mrj_p, (0:5/5), include.lowest=TRUE)) The issue is that, for Utah, I am getting an <NA> instead of (42,48.7] in

Hi, I am currently in the process of migrating from RH 7.3 to RHEL ES 3.0 on my system. Of course there is a lot of iles that will need to change server (new server is ready). My question is of course what is the best way to do this? My thought is rsync with a function like this: 1: Running rsync once to get all the files over to my new system 2: Running rsync several times to keep the files

Hello List, My goal is to apply a user-defined function on several columns of a data frame. When testing the code on a reproducible example below, I get the following error message. > #now Write a new function using the above cut ()/quantile function to apply on different columns of the data frame > > CutQuintiles <- function(x) { + cut (test1$x,quantile (test1$x,

Good afternoon! As mentioned in the subject, my question regards more the methodological part that accompanies survey design and the statistical part that is involved. So, I have the following data: a<-data.frame (id_hh=c(1:5), strata=c(1,1,2,2,1), Nhstrata=c(100,100,200,200,100), Nrmemb=c(2,4,2,5,4)) a$ocmemb1<-c("wk","jl","st","jl","st")
