Dear all, I met a problem when installing new packages on R, my system is linux fedora 6.0, the following is output. please help me.

Dear all, There is this delcol() function in Splus. It is a support function for drop1.lm(). But it seems it disappears from R. Could some one tell me whether there is any equivalent function of delcol() in R or is there any other way that I can implement its functionality? Your help is highly appreciated!!! Regards, -Ji

Apologies, basic question on plot. y <- c(-4,3,-2,1); x <- c("time 1", "time 2", "time 3", "time 4"); plot(x,y, type="b"); of course fails. x <- 1:4 makes it succeed, but then I have too many ticks on my X axis. I want exactly 4 tickmarks. It would also be nicer if I could name the ticks. I looked at ?par and Venables&Ripley,

Dear R-help, First of all, thank you VERY much for any help you have time to offer. I greatly appreciate it. I would like to write a function that, given an arbitrary number of factors from a data frame, tabulates the number of occurrences of each unique combination of the factors. Cleary, this works: > table(horse,date,surface) <SNIP> , , surface = TURF

This is a summary and extension of the thread "GLMM (lme4) vs. glmmPQL output" http://maths.newcastle.edu.au/~rking/R/help/04/01/0180.html In the new revision (#Version: 0.4-7) of lme4 the standard errors are close to those of the 4 other methods. Thanks to Douglas Bates, Saikat DebRoy for the revision, and to G?ran Brostr?m who run a simulation. In response to my first posting, Prof.

Hi All, could someone please shed some light on the proper goodness-of-fit analysis for the GLM output based on Gamma distributions with the log-link? My objective is to test the goodness-of-fit for the final model (and not the comparison of nested models). In particular, should the 'Residual Deviance' be compared with the Chi-Square distribution, or should the 'Scaled Residual

for some reason the controller is parsing everything fine, but the return is a page instead of code execution. I have other ajax forms no listed that are also running fine on this same page. there are supposed to be 3 ajax events: onblur event that calls a function to submit - doesn''t work. There is a submit button at the end of the form - works there is a delete image that removed the

Hi, all: I want to call a c program in the windows version R, so I compiled it in VC to get the dll file and use the command ?dyn.load? to call it in R. There is no error appeared for this command, but when I use the command ? is.loaded? to check, it shows that dll file isn?t be loaded. Does anyone have same experience or know the correct way to do it? Best wishes, Guan Xing 5/22/03

if I do: yyy=aov(Y~A*B*C); it seems that the three way ANOVA is based on all fixed-effects. There is no way to signal to "aov" the A and B are random effects and C is fixed effect; or A is random and B and C are fixed? Moreover, I guess I will need the Expected Mean Squares in order to do the F-test, where can I obtain these Expected Mean Squares in R? And is there a command that

Hello I'm trying to run a fortran code which use LAPACK subroutines. I think I should use some points shown in the manual 5.5 Creating shared objects but it is too technical for me :-(... Could anyone help me for the procedure to do: -which part of the manual is relevant for this type of question? actually I'm speaking from writing R extensions, should I read R admin? -point 1.2

Hi all, I have been previously been using scatterplot3d package to create some graphs but unfortunately it does not allow me to rotate the plot on all three axis. The cloud() function in the lattice package does allow me to do so. When I was using scatterplot3d I was using a script (Shown Below) to calculate the mean, quartiles and range limits for all three axis and I was representing that on the

Hi! Probably a simple question, but I can't get any tick marks in the 3d scatterplot I created using the cloud function. The following works to display the three groups using different symbols: data(iris) cloud(Sepal.Length ~ Petal.Length * Petal.Width, data = iris, cex = 1.2, groups = Species, pch = c(16,1,1), col = c("black","black","red"), subpanel =

(1) ?cbind claims The generic functions `cbind' and `rbind' take a sequence of vector and/or matrix arguments and combine them as the columns or rows, respectively, of a matrix. Note: The method dispatching is not done via `UseMethod(..)', but by C-internal dispatching. Therefore, there's no need for, e.g., `rbind.default'. but my cbind.ts

I've written a package to assist with using R in Hadoop Streaming. The main point of the package is to help make command-line runnable RScript files. I'd like to provide a demo RScript file, a demo data file (e.g. a plaintext file, not something already processed by R) , as well as demo bash shell scripts that demonstrate how to run the job from the command line and in a Hadoop

I've noticed quite a few messages relating to large data sets bedeviling R users, and having just had to program my way through one that actually caused a "Bus error" when I tried to read it in, I'd like to ask two questions. 1) Are there any facilities for aggregation of data in R? ( I admit that this will not do much for the large data set problem immediately) 2) Is there any

How does one rotate the loadings from a principal component analysis? Help on function prcomp() from package mva mentions rotation: Arguments retx a logical value indicating whether the rotated variables should be returned. Values rotation the matrix of variable loadings (i.e., a matrix whose olumns contain the eigenvectors). The function princomp returns this in the element

While working on 'random walk' applications, I got interested in optimizing noisy objective functions. As an (artificial) example, the following is the Rosenbrock function, where Gaussian noise of standard deviation `sd = 0.01` is added to the function value. fn <- function(x) (1+rnorm(1, sd=0.01)) * adagio::fnRosenbrock(x) To smooth out the noise, define another
