...the whole matrix is slow and the resulting matrix is tiny. Also the variable of interest for me is a binary var Y or N . Is there an efficient way to graphically view many variable relationships that does not look teeny ? I could do pairs 10 at a time but this seems too brute force. thanks Dhruv [[alternative HTML version deleted]]

...g can create terms but i want the columns to be part of the data set so that i can feed this into Random forest to pick out predictive interaction terms as regression cannot reliably handle correlated interaction terms. if anyone has some simple code that can do this that would be helpful. thanks Dhruv [[alternative HTML version deleted]]

...var1,var2 10,100 so I want to get .5, 60 back in a vector. This is a one row example but I would want to get a matrix of multiplied out coefficients and terms for use in comparing contribution of variables to final score. As in a scorecard using logistic regression. Please advise. thanks Dhruv

...ded now the function returns the rules along with Y and N count affected by the resulting rule. I am ccing the r-help post in case anyone wants to reuse this updated version as well. This is a great little function. Thanks for developing it and suggesting how to make the enhancement.

Hi, In a binary classification dataset is there a way to tune rpart to now allow any false positives. I.e. is there some setting that will enforce no false positives (prior etc)? (and yet Without making the tree pick all 0 or 1 outcome) Dhruv [[alternative HTML version deleted]]

Hi, Is there a way to get/extract a matrix of regression variable name, coefficient, and p values? (for lm and glm; which can be sort by p value?) thanks Dhruv [[alternative HTML version deleted]]

...ing column C is missing from the data. Anyway it seems like the models would be more compact without having to include within them data from the original data set used to build them but that is an aside. If models can be persisted and loaded selectively later that would neat. thanks Dhruv [[alternative HTML version deleted]]

...I do a summary so I can't -1 them away. 2) is there an easy way to then take my aggregate matrix and then format the sum wtih $ and commas. for e.g instead 10000 it should show $10,000.00? I am trying to create a report and am piping the aggregate into an xtable and feeding it R2html. thanks Dhruv ------------------------------------------------------------ Medical Billing and Coding Training ools. http://tagline.excite.com/fc/JkJQPTgMxYL8ba16zHPqHis4q6x4p3rbpaGcEAQIui8YyxCoQBNUxa/ [[alternative HTML version deleted]]

...w to LLVM. I am using an x86 code generator. I need to write a few passes based on cache blocks and data layout information. Does LLVM provide a way for me to see the data layout and analyze what are the cache blocks? If not is it possible to implement the same in the current framework?

...I wanted to know if there is an elegant and clean way to read in 1 csv file but to read the seperate matrices on different rows into seperate R data objects. if this is easy then I can read the 8 datasets in the csv file into 8 r objects and pipe them to time series objects for graphs. thanks Dhruv ------------------------------------------------------------ Email Fax It's easy to receive faxes via email.

...d group=B,C', ifelse(Age<=50 then group=N,A, 'Age<=50 then group=N,A'))) this way the rpart tree can be used to segment the data by the rule that does with it to do performance on each tree. any solution to traverse the rpart tree into if else statement would be helpful. thanks Dhruv Email transmitted across the Internet is normally not protected and may be intercepted and viewed by others.

Hi, How do I access the loop variables in a loop. for(i = 0; i < N; i++) for(j = 0; j < M; j++) A[i][j+k] = i + j; Is there anyway for me to know that in A[i][j+k], i & j are loop variables whereas k is not!

Hey Folks, I''m just starting to look into Puppet though am finding it a bit confusing as to how to get it setup on the network I administer. At the moment it is a combination of RHEL 4 and SLES 10 boxes with windows and novell also. I know that windows / novell is beside the point though am wondering how to get puppet setup on the RHEL and SLES side of things. Any good howto''s
