Dear All My data consists in 96 groups, each one with 10 observations. Levene's test suggests that the variances are not equal, and therefore I have tried to apply the classical transformations to have homocedasticity in order to be able to use ANOVA. Unfortunately, no transformation that I have used transforms my data into data with homocedasticity. The histogram of variances is at

Dear All, Is sqldf equipped with delete queries? I have tried delete queries but with no success. Thanks in advance, Paul

Dear All, When I am running a program under Wine and I press Control-C, the running program is killed. However, this behavior is not always the desired one. In truth, imagine that the program is doing some calculations that you want to interrupt; if one presses Control-C, the program is killed, but all one wanted was to interrupt the calculations and NOT killing the program. Is there some

Dear All, The following code should return 1, but it returns 0: source("http://r-bc.googlecode.com/svn/trunk/R/bc.R") bc("9 % 2") Do you confirm this bug? Paul

Dear All, Can R produce dot plots like the one of the following picture: http://en.wikipedia.org/wiki/Image:Dotplot_of_random_values.png ? I have tried dotchart, but no success. Thanks in advance, Paul

Dear All I am trying to perform the below optimization problem, but getting (0.5,0.5) as optimal solution, which is wrong; the correct solution should be (1,0) or (0,1). Am I doing something wrong? I am using R 2.5.0 on Fedora Core 6 (Linux). Thanks in advance, Paul ------------------------------------------------------ myfunc <- function(x) { x1 <- x[1] x2 <- x[2] abs(x1-x2) }

Dear All, To load a previously saved workspace, one can do the following: load("/path/to/the/saved/workspace/file") However, if the path to the saved workspace file is a web address, one gets the following error: ?Error in readChar(con, 5L, useBytes = TRUE) : cannot open the connection In addition: Warning message: In readChar(con, 5L, useBytes = TRUE) : cannot open compressed file

Hi there, I'm new to R and despite searching today, I can't find a function which will compute the adjoint of a matrix A. Does this adjoint function exist in R? Thanks in advance!

Dear All, I am trying to solve the following maximization problem with R: find x(t) (continuous) that maximizes the integral of x(t) with t from 0 to 1, subject to the constraints dx/dt = u, |u| <= 1, x(0) = x(1) = 0. The analytical solution can be obtained easily, but I am trying to understand whether R is able to solve numerically problems like this one. I have tried to find an

Dear All I am doing the following: > x <- yacas("3/2") > for (i in 2:400) + x <- yacas(paste(x,"*",x)) > x expression(Inf^1.260864167e+117/Inf^6.304320836e+116) > Eval(x) [1] NaN No luck this way. However, I am successful with > y <- yacas("(3/2)^400") > y expression(7.05507910865533e+190/2.58224987808691e+120) > Eval(y) [1]

Dear All, Consider the following code: plot(0,0) text(0,0.5,expression(italic(theta))) I would like to get theta in italic, but I always get it upright. Any suggestions? Thanks in advance, Paul

HiHo Hans, sorry, but I cannot see any tarballs shipped in [2]? Forgot to upload? Would like to give this pre-release a try on my Ubuntu/precise AMD64 system. Thanks in advance.

Dear All Can R compute the expected value of a random variable? Thanks in advance, Paul

Hello, I searched centos7 in the AWS marketplace for the at-time-of-writing-latest centos7 image: https://aws.amazon.com/marketplace/pp/B00O7WM7QW?qid=1524138193326&sr=0-1&ref_=srh_res_product_title I built a standard free tier t2.micro from this putative 1803_01 AMI. I see from the docs, this is thus a March 2018 compilation. When I get CLI, I get this: [centos at ip-172-31-27-32

Dear All, Suppose that you are trying to create a binary logistic model by trying different combinations of predictors. Has R got an automatic way of doing this, i.e., is there some way of automatically generating different tentative models and checking their corresponding AIC value? If so, could you please direct me to an example? Thanks in advance, Paul

Full_Name: Jens Lund Version: Version 1.7.0 (2003-04-16) OS: Win NT 4.0 SP 6 Submission from: (NULL) (193.3.225.210) As the T distribution is symmetrical around 0 qt(0.5,df) should return 0 for any df. However for df close to 1 it seems to have problems as seen by: qt(0.5,seq(1,1.1,by=0.0001)) For example: > qt(0.5,1.01) [1] -0.2300470 Higher df as df=1.1 (and up to approx df=1.7) seem
