[R] Erro updating HTML package descriptions in packages.html
Dear all, I have just installed the new version of R 2.7.1 and when i first instaled some packages it asked me to create a personal directory. It installed the packages, but not the html help page (packages.html) The downloaded packages are in C:\Users\jamaj\AppData\Local\Temp\Rtmp4MTuXN\downloaded_packages updating HTML package descriptions Warning message: In file.create(f.tg) : cannot create file 'C:\PROGRA~1\R\R-27~1.1/doc/html/packages.html', reason 'Permission denied' How can i fix the packages.html file to reflect the packages' instalation? Thanks in advance. José Augusto M. de Andrade Jr. (jamaj) Quant.

[R] Erro: cannot allocate vector of size 216.0 Mb
Please, I have a 2GB computer and a huge time-series to embedd, and i tried increasing memory.limit() and memory.size(max=TRUE), but nothing.

Re: [R] Erro: cannot allocate vector of size 216.0 Mb
Dear all, Thank you by your attention. 1) I'm using a Core 2 Duo CPU with 2MB physical memory and Windows Vista 2) The main function, that´s causing the error, is embedd(x=data,d,t). 3) The time series that i´m using has 1.000.000 observations of real numbers. 4) Sometimes the function works, sometimes, not. Some things i´m doing: 1) I have put x <- NULL and gc() in the end of each memory-intensive routine (embedding), to release memory. 2) I installed Ubuntu linux in the same machine and will try the same routine. "Efective men use Unix" :) And my plans to the future: 3) If this not work, i will try to rewrite the code to reduce memory requirements. 4) If this not work, i will try to parallelize the code, by using snow ou Rmpi, something like this. 5) If this not work, i will try to use a cluster, with sufficient memory to let this work. Any suggestions? Many thanks.

Re: [R] Erro: cannot allocate vector of size 216.0 Mb
Dear all, I have some news. First, i sucessfully installed Ubuntu 8.04 LTS in my notebook with R too. The problem simply disappeared. Now, i can embed my 1.000.000 observations time-series even in 20 dimensions without problem, in the same notebook. I'm writing this message to encourage people migrating to Ubuntu. W$ e M$ are shit.
