[Using XP, MySQL 5.0, Ruby 1.8.4] Hello, this is my first post. I am new to Ruby, coming from about 6 years of ''import java.util.*''s. I am using ActiveRecord, both on Rails and outside Rails. On Rails I have no trouble. Outside is where it gets confusing. I have created three tables (so far) and their three corresponding classes. Since I''m having the same

Hi, I am aware that it is impossible to netboot ISO files through pxelinux/memdisk and that there are multiple reasons for not even attempting it (like the operating system which will try to access a physical optical drive through its own drivers anyway, BIOS issues etc.). When people ask questions regarding ISO support in pxelinux/memdisk, they're mostly told to convert the ISO into a

Hi. I have a correlation matrix 'x' which is of size 923x923 I need to remove variables that are highly correlated. I don't have a sophisticated way of selecting which of the two in a highly correlated pair to remove. I thought I would just go through each entry of the correlation matrix and if it is greater than 0.6 (or less than -0.6) I will remove that column and then redo the

Dear all, I like to extract row names & column names from the named matrix...... like...... a<-matrix(1:6,2) ro<-c("aa","bb") co<-c("dd","ee","ff") dimnames(a)<-list(ro,co) a > dd ee ff aa 1 3 5 bb 2 4 6 from the above matrix "a" I like to extract rownames separately like

Can someone lend me a hand with extracting the dimnames from a SEXP? I've looked through R-exts, but I couldn't find an example. Here is the code I'm using to grab the jth column name and print it, but the colnames I'm getting are garbage. None of the following are working. void printInfo(SEXP ts) { int j; for (j=0; j<col; j++) {

I'm working with an historical image that may be (one of?) the first uses of gray-scale shading to show the pattern of values in a matrix/table, later used by Bertin in his 'reorderable matrix' and sometimes called a scalogram. The image is at http://euclid.psych.yorku.ca/SCS/Gallery/images/Private/scalogram.jpg The rows refer to the arrondisements of Paris, the cols to various

Hi, I have a vector of data, that I group based on two factors via tapply. For each such grouping I would like to plot a pie chart. I can layout these pie charts in a matrix layout, correpsonding to the levels of the two factors. But I am getting stuck on how to label the rows and colums. My current approach looks like this: x <- data.frame(obs=sample(c('low', 'high'),100,

Hello, I have a data.frame and I want to transfor it in a list of rows or columns. I can do apply(myDataFrame,MARGIN=1,FUN=???)

There's a bit of a symmetry issue, which may or may not be important (led to 15 seconds of confusion until I got my bearings straight): row.names, rownames; colnames, no col.names? I _NOW_ realize the difference between row.names and rownames, but is there any reason not to have col.names for re-naming columns in a data.frame? (if there is, I don't particular need to know it, but it

This bug was reported to r-devel by Martin Morgan on 13th May 2008 (original email pasted below). However I couldn't locate it in the bug tracker (with searches for row, col, as\.factor) It is still present in today's svn version (rev 47115). I hope I'm doing something useful by bringing it up again. I have not sent this to r-bugs, as I'm concerned that not locating it in the bug

Hi All, Currently I am investigating how interesting OGG is for me. The most important requirements are: - Decoding on embedded hardware, ARM7 or ARM9. - Mixing multiple audio streams/files on embedded hardware First of all how difficult is it to decode OGG on an ARM7/9 processor? I read that OGG decoding needs floating point support? Secondly I would like to know how many MIPS are needed to
