similar to: converting a string to an element in a function call

I would like to do some operations inside a function using only one value for the last dimension of a table/matrix: tabfn <- function (dfrm, facvec, YN ="event"){ return( Etbl <- do.call(table, dfrm[ , c(facvec, "event") ]) ) # just want Etbl[,,,"TRUE"] or Etbl[,, "TRUE"] or Etbl[,"TRUE"] }

I have the following problem. I have an automatically generated named list with "stringified" names: a <- list("A"=..., "B"=..., "C"=..., ) then I want to refer to the elements of the list, stored as an vector of names: nn <- c("A", "B", "C"), so that I could get list elements like a$nn[1], a$nn[2], etc. Obviously it

Hello everyone, I had a few questions that I have not been able to figure out despite a lot of reading. 1) Adding a title to a multiplot figure: If I plot multiple plots with >par(mfrow=c(2,6)) how do I add an overall title to the figure, not the individual plots? 2) Saving histories on the fly: Is there a .Rhistory equivalent to >save.image() ? I would like to be able to save the

Hi there, Suppose mu is constant, and error is normally distributed with mean 0 and fixed variance s. I need to find a statistics that: Y_i = mu + beta1* I1_i beta2*I2_i + beta3*I1_i*I2_i + +error, where I_i is 1 Y_i is from group A, and 0 if Y_i is from group B. It is large when beta1=beta2=0 It is small when beta1 and/or beta2 is not equal to 0 How can I find it by R? Thank you very much

Hi All I have been struggling with this model for some time now and I just can't get it to work correctly. The messages I get when running the code is: DLSODA- Warning..Internal T (=R1) and H (=R2) are such that in the machine, T + H = T on the next step (H = step size). Solver will continue anyway. In above message, R = [1] 0 0 DINTDY- T (=R1) illegal In above message, R = [1]

Dear all, I have two highly correlated variables (y and x), and both of them depend on a third variable (A, for Area). Multiple regression (y=a+(b*x)+(c*A)) would have collinearity problems, so I decided to do a partial regression to predict y. I did it this way: - I regressed y to A, and calculated the residuals (e_y) (reg1) - I regressed x to A, and calculated the residuals (e_x) (reg2)

Full_Name: Adrian Custer Version: 0.90.0 OS: Linux on Thinkpad (pentium) and desktop (K6) Submission from: (NULL) (128.32.251.234) When I create a boxplot, and then try to overlay a lowess fit or just the points, the points do not appear in the highest level and the lowess curve does not reach the highest level. However, if I add one to each of the models, the problem is solved. I tried this

I have written test.ll as below and ran 'opt' on it as " opt -std-compile-opts test.ll -S -o -" . But the output shows that there is code motion around the barrier intrinsics. test.ll ------- ; ModuleID = 'test.bc' define void @test(i16* %I_0, i16* %I_1, i16* %I_2, i16* %I_3, i16* %O_0) { entry: %T_0 = load volatile i16* %I_0 %T_1 = load volatile i16* %I_1 %T_2 =

Hello, Apologies if this question has already arised, hope you can help me to the find the solution to this or point the place to look at. I have a multidimensional piece-wise regression linear problem, i.e. to find not only the regression coefficients for each "interval" but also the beginning and ends of the intervals. To simplify it to the one dimensional case and two intervals,

Hello everyone, This question and associated comments come from a desire for more sanity in my object name space. These ideas may just be a whacky, way too difficult to implement or already possible with existing functions. Would it be possible to improve R's listing ability by adding the capability to list objects by type, creation date, modification date, ancestry and/or user comments?

Hi, I am now trying to write an alias analysis pass for LLVM 3.1. The pass is compiled into a .so library. When I loaded it into opt to perform evaluation with command: opt -load my-so-lib -aa-eval foo.bc the following errors occurred: opt: raw_ostream.cpp:261: void llvm::raw_ostream::flush_nonempty(): Assertion `OutBufCur > OutBufStart && "Invalid call to

Hi, Does your pass use multiple inheritance? Sounds like your problem is that you need to define getAdjustedAnalysisPointer, see: http://llvm.org/docs/doxygen/html/classllvm_1_1Pass.html#a03d3a81b1c46aff7c38ef3a6750ba225 An example implementation (very likely exactly what you want) is in LibCallAliasAnalysis: http://llvm.org/docs/doxygen/html/LibCallAliasAnalysis_8h_source.html#l00060 Hope

Hi R-helpers, I'm new to time series modelling, but my requirement seems to fall just outside the capabilities of the arima function in R. I'd like to fit an ARMA model where the variance of the disturbances is a function of some exogenous variable. So something like: Y_t = a_0 + a_1 * Y_(t-1) +...+ a_p * Y_(t-p) + b_1 * e_(t-1) +...+ b_q * e_(t-q) + e_t, where e_t ~ N(0, sigma^2_t),
