I tried to use gpuCor function in the gputools package of R to calcuate the pairwise correlations of a matrix of 40,000 columns. Becuase there would be memory issues if I use the whole matrix at a time, I splitted the matrix into submatrix of 10,000 columns and then calculate the pairwise correlation of different submatrices. There are altogether 4 submatrices, so I need to calculate the pearson

I have some data I would like to model which involves choice of food by dung beetles. There are a number of experiments where in each case, there are five choices. Overall there are more than 5 different foods being compared (including a placebo) and different experiments use different comparisons. The problem is a generalization of Bradley-Terry but it differs from some generalizations in

Since R is open source and help may come from varied levels of experience on R-Help, I wonder if it might be helpful to construct a method that can be used to "rate" those who provide help on this list. This is something that is done on other comp lists, like http://www.experts-exchange.com/. I think some of the reasons for this are pretty transparent, but I suppose one reason is that

Hi, I just wanted to verify the appdb rules/format so I correctly make my submissions in the future. I was surprised when I received an admin edit after submitting: http://appdb.winehq.org/objectManager.php?sClass=version&iId=22285&iTestingId=59851 recently. The game worked completely flawlessly for me, so I submitted it as a "Platinum" rating. However, since I had to set Wine to

Hi folks I've tried asking this in private mail for quite some time, but sadly got no reply. So I end up needing to raise the question here. Sangoma's s setup process includes a small patch to Zaptel. I have some technical reservations with that patch. It seems that under certain circumstances it may cause unexpected behavior when used with other Zaptel channel drivers. I also don't

I doubt your actual file looks like the mess that made it to my email software (below) because you posted HTML-format email. Read the Posting Guide, and in particular figure out how to send plain text email. You might try the "anytime" contributed package, though I suspect it too will choke on your mess. Otherwise, that will pretty much leave only a brute-force series of regular

Dear useRs: Is there a way to include a raster image (e.g., .gif, .jpg, .bmp) representing a company logo, a school logo, etc. into an R graphic? For example, it would be nice to be able to include the logo of the school into the charts that a student produces for her dissertation. Similarly, while working on a competitive analysis, it would be nice to be able to replace the names of the

Thanks Jeff. This is a nice way of solving this problem.

Is there a way to query for only the ratings of games running on the latest release build of Wine? I want to be able to see all the games rated for the last release (0.9.60), but haven't found an easy way to list that. Maybe I'm overlooking something? I don't want anything particularly fancy. Just a list of games (preferably sortable by rating... maybe votes?) and a list of their

Do you have other instances of R open at the time you are doing this? Did you already have mgcv installed in your personal library when you tried installing it again? There is clearly something preventing you from writing to your library, or at least to specific packages in your library.

So you are saying there are two problems... one that produces a corrupt file from a valid compressed file, and one that segfaults when presented with that corrupt file? Can you please confirm the file name and run md5sum on it and share the result so we can tell when the file problem has been reproduced? -- Sent from my phone. Please excuse my brevity.

It is not generally advisable to get too fancy with stat functions in ggplot... things can easily get more complicated than ggplot is ready to handle when it comes to calculations. It is better to create data that corresponds directly to the graphical representations you are mapping them to. Read [1] for more on this philosophy. [1] H.
