Dear all, I have the following problem. Given an expression object 'expr' containing a certain set of symbols (say 'a', 'b', 'c'), I would like to translate the expression object in an R function of, say, 'a', programmatically. Here an example of what I mean. Given: > expr <- expression(a+b+c) a call like: > asFunctionOf(expr, 'a',

Hello, my data is sorted by start.ens (see below). And now I would like to extract all rows (so called* defined row*s) with type==Expression - subset (df, type==Expression) - and the aforegoing type==DNase HS (which is not necessarly row n-1 - assumung that the defined row is n). I dont know how to add this to my subset command. Is that possible? Thanks Hermann > df start.ens fc.trans

Hi there. I have a data frame, X, with n+m columns. I want to regress each of the first n columns on the last m. This is what I am trying to do: for ( i in 1:n ) assign( paste ("reg",1:14,sep="")[i] , lm( X[,i] ~ X[,i+1] + ... + X[,i+m], data= X ) ) It happens that some of the regressions, say the 3rd, seems to be a singular fit (or something else I don't know

Hi all. A statistical question. I have to estimate the variance of the sum: X(1) + X(2) + ...+ X(n) from an observed sample, where X(i) are *correlated* and not necessarly identically distributed. Someone can suggest a simple strategy (I hope by exploiting some already present R package) for obtaining such estimate from an observed vector X[1:n]? Tnx all, Antonio, Fabio Di Narzo.

Hi, I am currently trying to learn RoR and there is something I cannot figure out. I have two models: Article and Category, that are HABTM-linked. Everything works fine if I want to select all articles corresponding to a category, with something like @articles = @category.find(@params[:id]).articles However, I have a ''published'' field in my ''articles''

Dear all, This is a pure statistical question, not necessarly related to R. I could not find it in literature. Suppose I'm intersted in a parameter rho, say, equal to: r=beta1/beta2, where beta1 and beta2 come from a linear model y=beta0+beta1X1+beta2X2+.... Fitting the model I can get the (biased) estimate of r=b1/b2, where b1 and b2 are the estimates in the regression model; I can get the

Attached is a patch to fix a GLIBCXX_DEBUG error in ScheduleDAGRRList. The problem is that calls to CapturePred may reprioritize elements in the priority queue, violating streak weak ordering requirements. To fix this, I introduced a reference wrapper for containers to obtain access to the SUnitVec used by std::priority_queue. When CapturePred runs, it calls updateNode which does a

I just installed a certificate on my mail server to Postfix and Dovecot. The certificate is functional on Postfix, but for some reason I keep getting this error. Any suggestions on how to fix it? mail dovecot: imap-login: Error: SSL: Stacked error: error:1408A10B:SSL routines:ssl3_get_client_hello:wrong version number Here is my configuration: # 2.2.22 (fe789d2): /etc/dovecot/dovecot.conf #

...r LLVM 2.8. Currently LLVM has a working JIT on x86, ppc (and perhaps arm?) AFAIK. It'd be great if sparc had JIT support too. I've seen that a very old version of LLVM had Sparc JIT support (don't know how well it worked), but it got removed when the v8 and v9 code was merged.

Greetings, <p>my apologies for putting this trash in the mailing list but the topic about SSE run-time option interested me pretty much. Looks like some people is really experienced on the topic. I would really appreciate if somebody could point me to good resources about SSE and Altivec (not necessarly on the net, I'm ready to invest some money if necessary). I already have intel

...;real" instruction. I do not think this would be possible: before register allocation, code is SSA form, thus the annotated instruction *must* preceeds the intrinsic annotating it. An alternative is to place the annotating intrinsic before the instruction who ends the specific live-range (not necessarely be an immediate predecessor). Just to point out a problem to cope with: instruction scheduling must be aware of this particular positioning of annotation intrinsics. > It's possible they could introduce extra spills and reloads, in that if > a value is spilled it would be reloaded befor...

It is not necessarely a good idea to use /usr/bin here... =) Ferenc, are you using systemd? If so, then you will discover under /tmp some private temporary directories, one of them is for dovecot, and your debug log is probably under there.

No, The way you check if SSE FP / xmm is supported is to issue an instruction with an xmm operand inside of a try catch loop: try { issue asm which uses xmm registers such as: pxor xmm0 xmm1 } catch(...) { if you get here an illegal instruction exception occurred then xmm registers are not supported. } Incidentally, in our case, just having an Atholon XP with Windows

Hi all, this is a question (really, not necessarly related to R) that I was not able to find in standard textbooks (at last those I've read, of course: Bates and Pinero, Lindsey). I'm fitting a linear mixed model with fixed part: X+A+X:A Just the interaction term X:A is significant suggesting an effect of X only in one group (suppose X is continuous and A is a binary variable, although
