Hello, I'm trying to make a 3D pie chart, but my labels are overlapping. I see that labelpos could offer a solution to this, but I have been unable to find any code snippets that indicate what type of value this argument requires. Any guidance would be appreciated! thank you, Tiffany

Hello, Is R very compatible with a Mac? A colleague of mine indicated that everyone he knows with a Mac has problems with R. What can you tell me about using R with a Mac. What do I need to download?

Hi, I would like to use a weighted lm model to reduce heteroscendasticity. I am wondering if the only way to generate the weights in R is through the laborious process of trial and error by hand. Does anyone know if R has a function that would automatically generate the weights need for lm? Thanks, -- Tom [[alternative HTML version deleted]]

Dear R-users, I'm currently using the multcomp package to produce plots of means with 95% confidence intervals i.e. mult<-glht(lm(response~treatment, data=statdata), linfct=mcp(treatment="Means")) plot(confint(mult,calpha = sig)) Unfortunately the y-axis on the plot appears to be fixed and hence if the labels on the y-axis (treatment levels) are too long, then they are not

How can I print the definition of a function that is in the base package? for example, if I type: which.min I get function (x) .Internal(which.min(x)) <environment: namespace:base> How can I see the definition of this function? Thanks.

Hi, I need to correct for ar(1) behavior of my residuals of my model. I noticed that there are multiple gls models in R. I am wondering if anyone has experience in choosing between gls models. For example, how should one decide whether to use lm.gls in MASS, or gls in nlme for correcting ar(1)? Does anyone have a preference? Any advice is appreciated! Thanks, -- Tom [[alternative HTML

Dear R-friends, How do you test the goodness of prediction of a model, when you predict on a set of data DIFFERENT from the training set? I explain myself: you train your model M (e.g. glm,gam,regression tree, brt) on a set of data A with a response variable Y. You then predict the value of that same response variable Y on a different set of data B (e.g. predict.glm, predict.gam and so on).

Has anybody gotten Apache-DBI to work under CentOS4? My installed rpms are: httpd-2.0.52-12.1.ent.centos4 (came with CentOS4) mod_perl-1.99_16-4.centos4 (came with CentOS4) perl-Apache-DBI-0.94-1.2.el4.rf (from Dag's site) --this includes Apache::DBI and Apache::AuthDBI In my '/etc/httpd/conf/httpd.conf' file, I added: PerlModule Apache::DBI

I thought I'd share this with the list since it appears to provide a quick fix to some memory problems, and I haven't see it discussed in relation to R. To reallocate virtual memory from kernel-mode to user-mode in 32-bit Vista or Windows 7 one can use the increaseuserva boot option value. See http://msdn.microsoft.com/en-us/library/aa906211.aspx On my 4GB Vista machine, R is now able to

Hi there, I want to make trajectory plots for data as follows: ID time y 1 1 1.4 1 2 2.0 1 3 2.5 2 1.5 2.3 2 4 4.5 2 5.5 1.6 2 6 2.0 ... That is, I will plot a growth curve for each subject ID, with y in the y axis, and time in the x axis. I would like to have all growth curves in the same plot. Is there

Hi, Can any one please explain why the following code doesn't work? Or can anyone suggest an alternative.

Forgive me if this isn't relevant, but: are you stripping off the output you need (e.g., parameter estimates) and throwing away what you don't (e.g., residuals)?

Greetings to everybody! Is there any way to turn off roaming profiles and use only local ones? In our company each of us connects to domain from its own workstation, so as I can see there's no need in roaming profiles. Why I'm asking such weird question? Because with roaming profiles Windows clients has readonly profiles! With Policy Editor I made HKEY_Local_Machine writeable,

Hi, I have a simple random-coefficients model for m subjects: y = b0 + b1 x + r0 + r1 x + e where b0 and b1 are fixed parameters, r0 and r1 are random, e ~ N(0,s2 I) and R' = [r0, r1] ~ N(0,T). I try to obtain the EM-estimates of s2 and the elements of T by lme(y~x,data=mydata,random= list(group=~x), control=lmeControl(maxIter = 0, niterEM=100,msVerbose = TRUE)) Does

Hello useRs, I have a problem at hand which I'd think is fairly common amongst groups were R is being adopted for Analytics in place of SAS. Users would like to obtain results for logistic regression in R that they have become accustomed to in SAS. Towards this end, I was able to propose the Design package in R which contains many functions to extract the various metrics that SAS reports.
