Can someone please show me what I need to get something like this to work for(a in c(1:5)){ data$a<-c(a:10) } so that i end up with a structure data$1<-[1,2,3,4,5,6,7,8,9,10] data$2<-[2,3,4,5,67,8,9,10] data$3<-[3,4,5,67,8,9,10] data$4<-[4,5,67,8,9,10] data$5<-[5,67,8,9,10] thanks loads Tom

Hi everyone, I'm hoping you can give me some pointers. I have a requirement to draw multiple (103) xy line plots onto one output device. Ideally the plots should be displayed in a hexagonal grid (example at www.maladmin.com/example.jpg). I can calculate the locations for each waveform but am wondering how to create multiple plotting areas. I have come accross references to a package grid

Can someone please give me a pointer here. I have two matrices matA A B C 1 5 2 4 2 2 4 3 3 1 2 4 matB A B C 1 TRUE FALSE TRUE 2 FALSE TRUE TRUE 3 FALSE FALSE FALSE how do I extract all the values from matA where the coresponding entry in matB == TRUE (or FALSE), perferably in vector form. Many thanks tom

I apologise for asking this question here but I am hoping that someone can either give me direct guidance and/or point me to a better group for this type of disucssion. I have what I feel should be a fairly simple problem but which my limited stats knowledge can't answer. I have two overlapping distributions (both normal) and I want to answer the question how do I calculate the cut-off value

I was able to install the curl library with no problems. However, when I tried to install ggplot (install.packages("ggplot2")), I got the same message as earlier, that R can't load internet.so.

I'm not an engineer so I hope I'm using the correct terminology here. I have a recorded waveform that I want to apply low and high pass filters too, are tehre already R functions existing to do this or am I going to have to program my own? thanks for any pointers tom

Can somebody please take a look at this and tell me whats going wrong? It seems to be parsing wronly around the 'if' statement and gives me a directory listing. Thanks in advance Tom N.B. datan is an invented dataset xvals<-c(1,0.4,0.2) datan<-data.frame(s1=c(3,4,5),s2=c(5,5,5),s3=c(21,55,34),s4=c(5,3,2)) datan$sint<-NA datan$sgrad<-NA for(icount in 1:dim(datan)[1]) {

Sorry to keep posting but I want to do this right and I'm hoping for some pointers I now have two time series objects which I need to subtract. Unfortunatly the two series dont have the same sample rates. When I try to subtract them avgSub<-avg1-avg2 The time series object is clever enough to object. So I guess I need to write a function for subtraction of the time series objects which

Can someone please explain what the $minimum result of the optimize function actually is? I'm trying to optimize the function: fitIT<-function(ampFac,ts_wave1,ts_template){ template<-stretchWaveTime(ts_template,ampFac) fit<-calcFit(ts_wave1,template) return(fit) } with >optimize(f=fitIT,interval=c(0.5,4),ts_wave1=test.data[,1],ts_template=test.data[,1]) $minimum [1]

Can someone please give me a clue how to 're'write this so I dont need to use loops. a<-ts(matrix(c(1,1,1,10,10,10,20,20,20),nrow=3),names=c('var1','var2','var3')) b<-ts(matrix(c(2,2,2,11,11,11,21,21,21),nrow=3),names=c('var1','var2','var3'))

Can someone please help me understand the examples given in the dwt function of the waveslim library library(waveslim) ?dwt I'm having a problem understanding these lines. I assume they are required because of how the algorythm deals with the signal bounderies. Am I correct in thinking that for wavelets of scale 1 and 2, the coefiecints need to be shifted by 2 places, for scale 3 and 4 shift

I'm trying to create an app using TclTk and R Can someone please explain how I bind a click event to the tree widget (http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/TreeWidget.html) Ideally I'd like to bind to particular elements in the tree but tkbind doesnt seem to work. thanks tom

I'm stuck on what I feel should be a minor problem. I have a dataseries obtained from a MS Access database that consists of a series of numbers seperated by carridge returns (\r) Currently this data is in R as mode numeric??? I want to separate this into a vector of the componant numbers. Perhaps a little code will help describe what I've got here!! library(rodbc) s_sql<-'SELECT

This code consistenly segfaults for me. Can someone please take a look and tell me if the problem is due to something I am doing or is there a problems with the dwt (idwt) functions in the waveslim library. Thanks tom library(waveslim)

Dear R useRs, I have a vector with positive and negative numbers: A=c(0,1,2,3,0,4,5) Now if i-th element in vector A is > 0, then i-th element in vector B is a+1 else i-th element in vector b=a (or 0) vector A: 0 1 2 3 0 4 5 vector B: 0 2 3 4 0 5 6 What's the right way to do this. I still have some problems with for and if statements... Cheers, Andrej

Hi, I would like to have 3d plot, and I found that there is a command "scatterplot3d". x is V, y=sigmaV, and z=TSE (note: After some calculation, I update TSE). How could I do to have 3d plot I want? V<-seq(1279,1280,,100) sigmaV<-seq(0.28,0.29,,100) TSE<-matrix(0, length(V),length(sigmaV)) ps: TSE[i,j] corresponds to V[i] and sigmaV[j]. Thanks, Kate [[alternative HTML

Can some help me spot what I'm doing wrong here. I have two equations, one a michalis-menton eqn and one a straight line. I need to work out where they cross.
