One correction... since you are fitting a logistic model, it is technically correct to say the "mean value of the linear predictor," instead of "mean response". 20 lashes for me.

Hi, I have a data frame with two factors (well, more, but 2 for simple consideration), and I want to display the different combinations of the them that actually occur in the data. In reality, there are too many of them to do to do a 'table' call and have one col vertical and one col horizontal (I don't want any of the factors listed horizontally). Before I try to write a function

On OpenBSD we still use the "classic" SunOS 4 shared library versioning scheme where the major and minor number are part of the library name (and recorded in DT_NEEDED entries). For example the shared libc on the OpenBSD-current is named libc.so.89.2. With this scheme, linker has to pick the pick the library with the highest major and minor (within the highest major version); the

Hi Mark, If we have to do this, or LLD doesn't work on OpenBSD, I think we need to do this. But can I ask one question? I wonder why OpenBSD systems don't have symbolic links unlike the other Unix-like systems in the first place.

Dear r-users, I am looking for an implementation of the Naive Bayes classifier for a multi-class classification problem. I can not even find the Naive Bayes classifier for two classes, though I can not believe it is not available. Can anyone help me?

I'm attempting to select a model using stepAIC. I want to use a forward selection procedure. I have specified a "scope" option, but must not be understanding how this works. My results indicate that the procedure begins and ends with the "full" model (i.e., all 17 independent variables)...not what I expected. Could someone please point out what I'm not

I got a shock a few days ago when I accidentally visited www.r-project.com . I thought that the r-project site had been hacked until I realised my mistake. There is also a site www.r-project.net. Both of these sites appear to be Japanese. Does anyone know anything about them? I suppose that it is not unusual for names close to those of popular sites to be used. It is good that they use a

libosinfo 1.8.0 declares them automatically for all of its classes, so there is no need to declare ours. This requires fixing the definition of the IS_LIBOSINFO_VERSION macro to wrap its body in brackets. While in the process, simplify the workaround for a related bug by removing a now-useless check. --- v2v/libosinfo-c.c | 11 +++++++++-- 1 file changed, 9 insertions(+), 2 deletions(-) diff

I found myself wanting to average a vector [vec] within each level of a factor [Fac], returning a vector of the same length as vec. After a while I realised that lm1 <- lm(vec ~ Fac) fitted(lm1) did what I want. But there must be another way to do this, and it would be good to be able to apply other functions than mean() in this way. Cheers, Murray -- Dr Murray Jorgensen

Consider the following: > A <- 1:10 > A [1] 1 2 3 4 5 6 7 8 9 10 > dim(A) NULL > dim(A) <- c(2,5) > A [,1] [,2] [,3] [,4] [,5] [1,] 1 3 5 7 9 [2,] 2 4 6 8 10 > dim(A) [1] 2 5 > dim(A) <- 10 > A [1] 1 2 3 4 5 6 7 8 9 10 > dim(A) [1] 10 Would it not make sense to have dim(A) = length(A) for all vectors?

I'm going to try my hand at converting some Fortran programs to R. Does anyone know of any good articles giving hints at such tasks? I will post a selective summary of my gleanings.

I want to interlace two vectors. This I can do: > x <- 1:4 > z <- x+0.5 > as.vector(t(cbind(x,z))) [1] 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 but this seems rather inelegant. Any suggestions?

Hey Sean, So the processor does in-memory computing, it reads instructions and operands from the memory array, performs the majority operations within the memory array itself. It does instructions using resistive majority which is AB'+B'C+AC Like it does AND operation as 1: 0, 1, @C; //C=0 2: 0, 1, @Binv; //Binv=0 3: 1, @B, @Binv; //Binv=B 4: @A, @Binv, @C; //C=A.B where each operation is

Well I don't know if anyone can help with this but it will be interesting to know if others have had the same problem. I can't start R at home on my laptop [ I'm using 1.8.1 under Windows XP]. When I click on the shortcut I get the usual Windows box for when an application needs to close. A couple of clicks down it displays the following: Error signature AppName: rgui.exe

Has anyone got a cute way of compiling a table of the available plotting symbols?

I wanted a sort of matrix product of an array and a matrix. As there does not seem to be any array multiplication apart from outer() I proceeded as follows: lambda <- array(0, c(n,m,d)) # stuff omitted # zed is an n by m matrix # # \lamb.star_{ik} lamb.star <- matrix(0, nrow=n, ncol=d) for (i in 1:n) { for (k in 1:d) { for (j in 1:m) { lamb.star[i,k] = lamb.star[i,k] +
