I would like to run a loop in R. I have never done this before, so I would be very grateful for your help ! 1. I have a sample set: 25 objects. I would like to draw 1 object from it and use it as a test set for my future external validation. The remaining 24 objects I would like to use as a training set (to select a model). I would like to repeat this process until all 25 objects are used as a

Dear all, I was playing around with some C-code that I dynamically linked to R and noticed the following inconsistency: > dat <- matrix(1,3,3) > is.double(dat) [1] TRUE > is.integer(dat) [1] FALSE > dat <- matrix(1:9,3,3) > is.double(dat) [1] FALSE > is.integer(dat) [1] TRUE How did I find out? I passed `dat' to a double * in the C-code and printed out the matrix

Dear Anton, Thank you again for your help! I tried with the following options (adding --with-cpu=arm7tdmi and using binutils from cvs snapshot): ../llvm-gcc4.2-2.6.source/configure --prefix=/usr/local/cross-llvm-gcc-arm-elf-4.2-2.6 --program-prefix=llvm- --enable-llvm=/Users/dummy/Develop/llvm/llvm-build --enable-languages=c,c++ --host=i686-apple-darwin9 --build=i686-apple-darwin9

Hello, Pazzo > Any clue? Yes. Sorry, my fault - next time I should check ARM docs before replying. ARM7TDMI is ARMv4T and this is not supported by LLVM (LLVM does v5+ codegen). -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University

Dear UseRs called Hadley, or Paul, I am trying to print an edited ggplot2/grid graphics to a metafile. With the commented line below it works, but when I edit the plot by uncommenting the line, it fails, because it's illegal to have 2 graphics in a metafile. It works with pdf, but even then I get two plots, which is a nuisance. I found a workaround by using windows(); savePlot, but it only

Hello all, I''m new to prototype and javascript isn''t my strong point. I''m trying to get a simple test script to work, which is turning out to be a little harder than I thought. I have a bunch of fields that I need to be able to switch on and off using one of a few hashes. In the example below I''m trying to get one to work. The problem occurs when I try to

Dear ML, Anton, Thank you for your answer and your help. I had a look at ARM.td of LLVM 2.6 (in lib/Target/ARM..) where I found following definitions: // V4T Processors. def : ProcNoItin<"arm7tdmi", [ArchV4T]>; def : ProcNoItin<"arm7tdmi-s", [ArchV4T]>; def : ProcNoItin<"arm710t", [ArchV4T]>; def :

Slightly off topic, but maybe some can suggest something off list... Trying to upgrade a 7960 that was running skinny. I've got sip v3.2.0 installed and running, and am able to place calls via *, etc. However, when upgrading to v4.4.0 I can never get to the point of being able to place a call (eg, no dialtone, etc). I can ping the phone, look at the Network Config, etc, but I can't

Hi All, when doing CVlm cross validation, I would just like to view the overall MS but i am having trouble getting just this value. I'm kina new to R. Any help really appreciates. Cheers, Ben -- View this message in context: http://r.789695.n4.nabble.com/Returning-overall-ms-for-CVlm-tp4664690.html Sent from the R help mailing list archive at Nabble.com.

Hello, I did a cross-validation using cvlm from DAAG package but wasn't sure how to assess the result. Does this result means my model is a good model? I understand that the overall ms is the mean of sum of squares. But is 0.0987 a good number? The response (i.e. gailRel5yr) has min,1st Quantile, median, mean and 3rd Quantile, and max as follows: (0.462, 0.628, 0.806, 0.896, 1.000, 2.400) ?

Can anyone help explain to me why the two codes below have different result? I thought I can use log(time)~. to replace log(time)~dist+climb+timef.I am using CVlm from DAAG package. I think nihills is preloaded with the package. Thanks in advance. > CVlm(df=nihills, form.lm=formula(log(time)~.),plotit="Observed",m=2)Analysis of Variance Table Response: log(time) Df Sum Sq

Hi, everyone When I was using cv.lm(DAAG) , I found there might be something wrong with it. The problem is that we can't use it to deal with a linear model with more than one predictor variable. But the usage documentation hasn't informed us about this. You can find it by excuting the following code: xx=matrix(rnorm(20*3),ncol=3) bb=c(1,2,0) yy=xx%*%bb+rnorm(20,0,10)

Dear R-list, I'm not sure what I've found about a function in DAAG package is a bug. When I was using cv.lm(DAAG) , I found there might be something wrong with it. The problem is that we can't use it to deal with a linear model with more than one predictor variable. But the usage documentation hasn't informed us about this. The code illustrates my discovery: > library(DAAG)

Hello, I used the cv.lm function to validate a linear regression model fit<-lm(y ~ x1+x2+x3+x4+0, data=mydata) without intercept I tried to validate the model by performing a leave one out cross validation procedure usinfg the cvlm function: CVlm(df=mydata, fit, m=196) But how can I get the adjusted R? from the output of this function. Or is there any other function to

Dear community, I'm trying to examine my grouped data following page 6 http://cran.r-project.org/doc/contrib/Fox-Companion/appendix-mixed-models.pdf.

Dear community, I have fitted a model using comands above, (rlm, lmrob or lmRob). I don't have new data to validate de models obtained. I was wondering if exists something similar to CVlm in robust regression. In case there isn't, any suggestion for validation would be appreciated.
