Re: [R] tempfile problem

take the name returned by tempfile and append the current TOD; this should make it fairly unique and will let you do some cleanup if you are going to keep the files around for some length of time. On Thu, Jun 17, 2010 at 12:43 PM, Ben Madin wrote: > G'day all, > > The documentation for tempfile s

Re: [R] Problems using allEffects() (package effect)

Please, read the posting guide: - provide a minimal example - tell us from which package the function is coming I guess you used the function allEffects() from the package effects, and did : eff.lm1 <- allEffect(lm1) Then I guess that there's something wrong with the variables you put into the mo

[R] library(...,pos=) is not consistent

I want to be able to load a library in a specified position using the pos= argument and have any subsequent library required by the one I'm loading go into a specified library as well. For example, in loading caret, it requires and loads lattice as well. When I specify that caret goes into positi

[R] program R using mac Xcode

Hi, I am starting to use Xcode a lot for C/C++ programming. Can you do R programming in Xcode? If can, how to configure to enable this? Much thank in advance. -- Waverley @ Palo Alto __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman

Re: [R] R licensing query

Worst case scenario you can install R as a user as well, you don't need administration rights. Regarding data analysis in Excel : http://www.pages.drexel.edu/~bdm25/excel2007.pdf : peer reviewed Other sources : http://www.coventry.ac.uk/ec/~nhunt/pottel.pdf http://www.forecastingprinciples.com/f

[R] Optimization problem

Sorry, thought you wanted to find lowest value of x that produced maximum value of y. I see now that is not the case. I think you have to decide on what amount of improvement per device you judge to be 'minimal'. Then the algorithm uses the value of y that occurs at the point where this criterion

I actually need to plot all of my confidence interval for x and y axis but it seems error.crosses only plot the common ones. But thanks for suggesting error.crosses. Please let me know if I can specify some option in eror.crosses to implement that. Any idea about how to plot all confidence interva

Re: [R] Question regarding print

The cat function is probably the best approach, but if your really feel the need to use print then you can just assign blank names (now it will be a named vector and slower in heavy calculations, but the printing is different). Try something like: > names(x) <- rep( '', length(x) ) > print(x)
