Hi, I am trying a for loop from 1 to 100 by 1. However, if a condition does not get met, I want to "throw away" that iteration. So if my loop is for (i in 1:100) and i is say, 25 and the condition is not met then I don't want i to go up to 26. Is there a way to do that? I can't seem to manually adjust i because from what I understand, R creates 100 long vector and uses that to

Is there a way to associate text descriptions with variables in a data.frame? For example... Let's say that in my data.frame I have a variable named var1. var1 represents the responses to the question "When was the last time you saw your physician?" When I tabulate the variable var1 I'd like the output to be a bit more descriptive and contain the more descriptive

Hi, friends. I keep coming to you because I'm so new to R and can't seem to figure out some simple things. Sorry. Consider the following code. I want to load a table and write out the structure to a PDF document. I just can't seem to manage writing non-graphic output to PDF. Any help? I've tried several functions, but nothing worked. All I get is the title. #

surely this not hard, but i can't figure it out. i'd like to overlay the results of two ecdf's. e.g. xx<--ecdf(x) and yy<--ecdf(y). i'd like to plot xx and yy on the same graph. thanks...mj [[alternative HTML version deleted]]

Hi, I'd like to return the rows of sampled values of a vector. Can't figure out how to do it. For example: I start with [3, 1, 7, 4, 10] that have position [1,2,3,4,5]. I sample [10,1,4] and I want to return [5,2,4]. I'm sure there's a simple way to do that but haven't been able to figure it out or locate it. Thanks in advance...mj [[alternative HTML version

Hi, all. I'm new to R. I've been a SAS programmer for 20 years. I seem to be having trouble with the most basic task - bringing a table in an *.RData file into a data.frame object. Here's how I created the *.RData file. library(RODBC) db <- odbcConnect("*******") df <- sqlQuery( db , "select * from schema.table where year(someDate)=2006" ) save(

hi all, i'm trying to get elements in a matrix into a vector. i need a "streamlined" way to do it as the way i'm doing it is not very serviceable. an example is a 3x3 matrix like 0 0 3 2 0 0 0 4 0 to a vector like 3 2 4 thanks...mj [[alternative HTML version deleted]]

Is there any such thing as a program file in R? That is, is it possible to compile and save code for performing data management and analytic tasks for a given project into a single/multiple file(s) (i.e., like a script file (S-Plus), a do file (STATA), or a *.sas file (SAS))? Any words of wisdom or a point in the direction of some documentation would be helpful. If it is not possible to work

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,

Hi, Wasn't sure how to explain this problem succinctly in a title. I am trying to read in a text file that looks like: 0 1000 175 1 2 3 1 1000 58 0 2 9 2 1000 35 0 1 3 10 3 1000 300 0 2 4 5 10 11 18 4 1000 150 3 5 6 5 1000 100 3 4 6 7 18 6 1000 50 4 5 7 8 7 1000 155 5 6 8 19 8 1000 255 6 7 19 9 1000 200 1 10 12 10 1000 52

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

I have several newbie questions - any help much appreciated: 1. I run a combination Windows 98 and XP home network - have been looking at Linux on two boxes at home - one desktop - one laptop - RH 7.3 2 I can get samba to run okay and in each of the two Win98SE machines can see them as localhost 3. I cannot access any resources on the Linux machines - Win98 asks for a password - \\localhost\IPC$

I have found that specifying different "sizes" in the sample command has a funny effect on the random sampling. The code below is a condensed version of a function I wrote to simulate a bootstrap method. For simplicity, I eliminated the internal bootstrap loop, but kept a statement to draw one bootstrap sample, because this is where the problem occurs. The output (mean(y)^2) should be

Do the socket options still work with versions of samba above 1.9.16p10? I get error messages both on the command line and in the smb.log file that say: Unknown socket option IPTOS_LOWDELAY Unknown socket option TCP_NODELAY Here is my smb.conf Global parameter entry: socket options = IPTOS_LOWDELAY TCP_NODELAY Do these have to be compiled into the Samba program? If these are outdated

Good afternoon, I am playing around with GlusterFS 3.1 in CentOS 6 virtual machines to see if I can get of proof of concept for a bigger project. In my setup, I have 4 GlusterFS servers with two bricks each of 10GB with XFS (per your quick-start guide). So, I have a total of 8 bricks. When bu I have no problem with distributed-replicated volumes. However, when I set up a striped replicated

Hi R package developers. This is literally the strangest thing I've ever seen. Latest (as of a month ago) R under cygwin64. I'm teaching an intern package building and using the .C interface. The package compiles, but when it gets to "setting up lazy load" or some such it throws the error "triang" not available for .C() in package "randpkg". Upon checking,
