similar to: Use keep.source for function in package with lazy loading

Recently Brian Ripley had occasion to mock my inability to see a comment in the code for arima(), in the stats package. After considerable dredging around in the r-news archives I found reference to keep.source() and keep.source.pkgs(), which I conjectured just ***might*** possibly be the ``obvious'' resource to which Prof. Ripley thought I ought to have resorted. However, after

I think SAS Macros has capability to call R, and execute it without it being in the picture anywhere. So you can use SAS Macros in a file called R.sas In this you can create a macro called %Describe that can call R , load Hmisc ,run the describe function Note you will need repeated use of %put in this %describe for the mapping to take place Use %INCLUDE to include that file in all SAS

Oh sorry. An example say lots more than words. The data below, when submitted to twoord.plot return the mentioned error. Rain are bars and Salt lines, the bars appear and the error occurs with the salt data.

Hi David: If your variables are in a dataframe called DF and the dependent variable is in the first column , you can do below but you probably are well aware of this anyway. lmresults<-lapply(names(DF[,-1],function(.name) { lm(DF[,1] ~ DF[,.name], data=DF) }) This will run through each of the variables in the dataframe and regress the first column on each variable individually. On

I have some functions that write an external text file for postprocessing by another program. Some instructions to the other program need to be indicated by null values (\000 or ^@). The function currently uses code like: writeChar(rawToChar(as.raw(0)), con) where con is a connection to the file. Previous to version 2.8.0 this worked fine. With 2.8.0 it still works, but I get a warning

Does anyone know how to change the background color of the script window(s) in Rgui on Windows? I can use the "Gui Preferences" menu item under the Edit menu has an option that lets you change the background color for the console window and any help/info windows that pop up, but the script window(s) still have the white background. Am I missing a setting somewhere? Is this a missing

Hi, I have finally installed TeachingDemos trough zip file and installed on lbrary. One new question: I want to draw a line (like abline) on diagonal or the result of running a ols. How can I do it. On the other hand, I want to mark the length on each sub plot y axis. It is possible? My function is sca<-function(){ z2<-read.table("Ase.txt",header=T)

I am working with the mcnemar.test function and the help does not show a maintainer/author, but it is part of the stats package. My issue is that I want to use the test on 2 variables with possible values of 0:3, in one of the tests one of the variables does not have any 3's, so to make sure that the matrix is square I do: > x <- factor(x, levels=0:3) > y <- factor(y, levels=0:3)

This problem can be seen by the following commands: > pb <- winProgressBar(max=1000, label='0') > b <- 1 > setWinProgressBar(pb, b, label=b) This set of commands (on windows of course, XP in this case) causes R to crash. This is not strictly a bug since the documentation states that the label argument should be a character string and using as.character(b) does work

Hi Dr. Snow, I am a graduate student working on analyzing data for my thesis and came across your post on an R forum: The default link function for the glm poisson family is a log link, which means that it is fitting the model: log(mu) ~ b0 + b1 * x But the data that you generate is based on a linear link. Therefore your glm analysis does not match with how the data was generated

This is a low priority bug that has been around for a while, but I came acr= oss it again while alpha testing 2.8. The resulting function for splinefun gives incorrect deriv values when x is= less than the smallest x-value used to create the function (at least in on= e circumstance), but does the correct thing for x greater than the largest = x-value. Here is an example: > x <- 1:10 >

This is to announce an updated version of the blockrand package has been uploaded to CRAN. The blockrand package is used for creating randomizations for clinical trials or other studies where random assignments are made one at a time. It implements the ideas of randomizing within blocks so that the numbers of subjects in each group remain fairly balanced (but allows for unbalanced blocks to make

This is to announce that versio 2.0 of the TeachingDemos package is now on CRAN (and hopefully soon to a mirror near you). This is a major upgrade of the package, some of the improvements include: The package now uses an NAMESPACE so it is easier to load just the parts that you need. Some of the GUI demonstrations now use tkrplot so that the graph is in the same window as the controls (there

The tkrplot package is not working in version 2.13.0 for windows. I contacted the maintainer who unfortunately does not have easy access to a windows computer and says that it is working on the other platforms. I traced the problem down to the line in the .First.lib function: .Tcl(paste("load", file, "Rplot")) With file being "C:/Program

Here is a demonstration of behaviour that is probably an optimization by someone far smarter than me that did not anticipate anyone wanting to do this, but for my purposes it looks more like a bug than a feature. I have tested this with R2.6.2 on Windows, no additional packages loaded (beyond the default), I have tested using the default graphics object, pdf, jpeg, and cairoDevice (ok I loaded a

Thank you, Greg, and also to Scott Ellison, who replied privately. I am in the process of trying out both suggestions. After I sent my initial message, I came across the Systemfit package, which allows specification of constraints on parameters. In theory, this should solve my problem perfectly. However, I was not able to get it to work with my data, as every attempt yielded the following
