Hi, I have searched the archives and help manuals and can not find anything regarding how to save multiple plots/graphs into a single for example, pdf file. There is plenty of discussion etc. about saving a single plot to a single file, but not multiple plots to a single file. Is it possible? I can't want to use lattice, because I have hundreds of plots. So, to keep it simple, let's say

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

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

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. #

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 If these are outdated

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 looking for some hints on idiomatic R usage using 'lapply' or similar. What follows is a simple example from which to generalize my question... # Suppose, in this simple example, I want to plot a number of different lines in different colors; # I define the colors I wish to use and I plot them in a loop: d<-

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! I need to plot two lines on the same graph. I do plot(x,y) then plot(x,z,add=TRUE) but I get the following warning messages Warning messages: 1: parameter "add" couldn't be set in high-level plot() function 2: parameter "add" couldn't be set in high-level plot() function 3: parameter "add" couldn't be set in high-level plot() function 4:

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 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$

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

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
