Hi there, I need help with IFELSE function. The column g of my dataset pth, pth$g consists of "aa", "ao", "dcl", "iy", "sh". The last few values of pth$g looks like: [4496] sh ao ao sh iy dcl dcl aa iy iy aa sh ao ao Levels: aa ao dcl iy sh I want to convert these values into 1,2,3,4,5. I tried to use a loop and I found the following

Hi All, I'm a little stumped by the following problem. I've got a dataset with the following structure: idxy ix iy country (other variables) 1 1 1 c1 x1 2 1 2 c1 x2 3 1 3 c1 x3 . . . . . 3739 55 67 c7 x3739 3740 55 68 c7 x3740 where ix and

Hey all Im having a problem... Ok, this is the situation... I have a small product image, on which ive floated a div over it, and defined it as draggable. Now, this works, and i can drag it around no problem. great. but then, what i want to do is, based on the location of that dragable element from the top and the left, to move (using the Effect.MoveBy method) a larger image - so effective

Hi, Currently the `gaussian' family's initialization code signals an error if any response data are zero or negative and a log link is used. Given that zero or negative response data are perfectly legitimate under the GLM fitted using `gaussian("log")', this seems a bit unsatisfactory. Might it be worth changing it? The current offending code from `gaussian' is:

Hi, I have a vector Y1 <-c(8, 11, 7, 5, 6, 3, 6, 3, 3) and an index iy <-c(c(1, 2),c(1 2), c(1, 2, 3, 4), c(2, 3, 5), c(4), c(5, 6, 7), c(7, 8, 9)) how can I produce the mean, or the sum of the elements specified in the index iy from the vector Y1? expecting something like this for the sum: Y2 19 19 31 24 5 15 12 I thought lapply function may perform this, but does not work:

Error in Math.factor(c(2L, 1L, 1L, 1L, 1L, 3L, 1L, 1L, 1L, 1L, 1L, 1L,  :   log not meaningful for factors In addition:Warning messages: 1: In Ops.factor(LRUpBound, LRLowBound) : * not meaningful for factors 2: In Ops.factor(TransitCoefStdDev, TransitCoefMean) :   / not meaningful for factors [[alternative HTML version deleted]]

Dont know if iys the done thing, but I contacted the writer of an app I maintain in AppDB, to point out that his app runs perfectly under Linux and Wine. Straught away he modified his webpage to include the fact, and a link to the AppDB page for his application. Cheers, Ron. -- I pr...

Dear all; Does anyone know how to add grid lines to a persp plot? I've tried using lines(trans3d..) but the lines of course are superimposed into the actual 3d surface and what I need is something like the plot shown in the following link: http://thermal.gg.utah.edu/tutorials/matlab/matlab_tutorial.html I'll appreciate any ideas Thanks PM

``We all know'' that R has more flexible and nicer color specifications than S-plus. There are situations however, where I'd like to specify colors numerically, e.g. 1) convenience of using different colors in a for(.) loop or 2) backward compatibility with S. In S, there's the quite known ``standard'' col = 0 :<==> current background color [ = white by

I have a question about antialiasing when R generates bitmaps. (This follows a thread on the ggplot2 mailing list.) I mostly use R on Linux, although I sometimes use it in Mac and Windows as well. On Linux, I've found that plotting shapes 15-18 via cairo results in bad-looking output. The points are not antialiased, and they are jagged and misshapen. Plots generated in Windows also aren't

Hello again. Thank you for the comments. I have written these codes. iy=function(x) { res=NULL ress=0 for (i in (1:2)) { for (xx in x[i]) { fy=function(y) (exp(-exp(y+log(xx)))*(-exp(y+log(xx)))^2)/(1-exp(-exp(y+log(xx)))) res=c(res,integrate(fy,-6.907,-1.246)$value) ress=ress+res } } return(ress) } iy(c(1,1)) integrate(fy,-6.907,-1.246)$value In 1D optimize() works perfectly on iy(). However

Yes, such optimizations are something for the "last 20%" of the project, nice to have's. As of now, I have yet to get a feeling of what LLVM can do on its own, depending on what it's from the instruction tables and where it needs help, and how much in other processing stages. As this affects the way how the instruction info table will be set-up, I appreciate your suggestions

Dear List: I am having to build a block-diagonal matrix (vl) and am currently using the following code. I<-diag(sample.size) vl<-kronecker(I,vl.mat) This code works fine, but for large N, it is a huge memory hog. Is there a more efficient method for constructing vl? Thanks, Harold [[alternative HTML version deleted]]

Hello, Can anyone help me out with this problem? After performing logistic regressions and testing the significance with likelihood ratios, I have plotted the results using "termplot". I am wondering, how to get the names of my variables to appear on the x-axis rather than ascending numbers? I have used: termplot(fm, se=T, axes=FALSE, col.se="black") axis(1, 1:4,

For a Z80 backend, "eliminateCallFramePseudoInstr()" shall adjust the stack pointer in three possible ways, e.g. after a function call, depending on the amount (= adjustment size) *and some other rules*: 1. via one or more target "pop <reg>" instructions (SP increments +2 per instruction), using an unused reg (disregarding the contents after the operation), followed

I've found the need to compute a version of order(x,y) where I want the sort order for *increasing* x and *decresing* y ... something we could imagine could be provided in the future as order(x,y, decreasing = c(FALSE, TRUE)) i.e., using a 'vectorized' decreasing argument. {No, I'm not volunteering right now!} I've found the following R-level solution and like to quiz

This is a question about optimizing the code generation in a (new) Z80 backend: The CPU has a couple of 8 bit physical registers, e.g. H, L, D and E, which are overlaid in 16 bit register pairs named HL and DE. It has also a native instruction to load a 16 bit immediate value into a 16 bit register pair (HL or DE), e.g.: LD HL,<imm16> Now when having a sequence of loading two 16

Hi all, I am using c++ functions in R by Rcpp and inline packages. The code is quite simple, but the R session always automatically crash after some running time. Does anyone here familiar with Rcpp and inline? What¡¯s the problem in the following code? I have checked the input values, no NA and other strange value exists. Thank you for your attention! > mkc <- cxxfunction(

Hi list, I have a question on how to identify the overlapped items from two vectors: >x<-c(0,1,2) >y<-c(1,2,2,3) and plot the number of the overlapped as well as non-overlapped in a diagram? Thanks much, Allen [[alternative HTML version deleted]]
