Dear all, I've run into a question of handling large matrices in R. I'd like to define a 70000*70000 matrix in R on Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit), but it seems to run out of memory to handle this. Is it due to R memory limiting size or RAM of my laptop? If I use a cluster with larger RAM, will that be able to handle this large matrix in R? Thanks much! Best, Hui

I noticed that nls treats weights as relative and that the absolute size of the weights w in the following script has therefore no influence on the errors of the parameters reported in the summary a<-1 b<-3 x<--100:100 y<-a*x+b yeps<-y+rnorm(length(x),sd=1) w<-rep(1,length(x)) plot(x,yeps) lines(x,y) fit<-nls(yeps~p1*x+p2,start=list(p1=a*1.5,p2=b*1.5),weights=w)

Hi all, Lets say I have a matrix A which is m x n. I also have a mask matrix MASK which is m x n with values in T/F, where T values make a sub-matrix in regutangular shape... I applied B=A[MASK] and it didn't work as expected... Any thoughts? [[alternative HTML version deleted]]

Hello, (Sorry for the repost, i am resending in plain text) I have a function 'ewrap' (see below for definition). It takes 3 expressions and returns another expression e.g. map <- ewrap({ len <- length(r$addon) rhcollect(len,1) }) becomes: expression({ NULL result <- mapply(function(.index, k, r) { { len <- length(r$addon)

Hi, here i have some code... a <-1 b <- b+1 c <- b+a/20 if c >5 { d<- 1 } else { d<- 0 } i want to repeat this code from the 2nd line [b <- b+1] without using loop. Actulay i want to use "*Label *" and call *GoTo* method like in other coding Languages. For eg:- like this, a <-1 *LabelBegin :* b <-

I have photographs of plots that look like so: http://r.789695.n4.nabble.com/file/n4631960/Untitled.jpg I need to divide it up so each circle has an equal area surrounding it. So into 20 equal segments, each of which contains a circle. Quadratcount is not sufficient because if I divide it up into 36 equal quadrats, some quadrats do not contain one of the circles. I'm not even sure how to

Dear R Users: I'm a STATA user converting to R, and I'd like to be to do the following. #Assign var_1 and var_2 a value 10->var1 20->var2 #Now I'd like to print the values of var_1 and var_2 by looping through var_1 and var_2 in such a manner: while(y<3){ print(var_y) y+1->y } In STATA, the "y" appended to " var_" is called the local variable and

Dear All, I have been searching online for help increasing my R code more efficiently for almost a whole day, however, there is no solution to my case. So if anyone could give any clue to solve my problem, I would be very appreciate for you help. Thanks in advance. Here is my issue: My desktop is with i7-950 Quad-core CPU with 24Gb memory, and a NVIDIA GTX 480 graphic card, and I am using a

Hi, I have a LLVM IR file generated for a different source language (Not C). I have added a rand() function in it to generate random numbers. I compiled the .ll file to .o using clang. However, when I execute the .o file all generated numbers are zeros. How should I link the .ll file with the standard library for the clang to generate the random numbers? Thanks -Shilpa -------------- next

Hello, Is there a convenient way to import RDF/OWL data into R? I'm interested in importing BioPAX/SBPAX data into R to make them available for a wider audience. One exciting application would be to use pathway data to explain differential microarray measurements by identifying upstream nodes that are likely involved in causing the differences. This could also be used to validate

Dear all, I'm looking for a function that calls the inverse F-distribution. Something equivalent to FINV in matlab or excel. Does anyone know if such a function already exists for R? (I haven't been able to find one.) Thanks for any leads. Best, Jennifer

Hi, First of all thanks for your answer, today has increased cpu usage, only change is add a new group with 3500 users, It could be the problem? a last question, now we only have one dc, no replication. If we add another dc will increase performance and will be a loadbalance the load? Now I can't upgrade to 4.7, I have to shcedule an upgrade and make test, any suggestion or a workaround?

I am trying to upgrade to the LLVM v4.0 branch, but I am seeing failures in my TableGen descriptions for conversion from FP32 to FP16 (scalar and vector). The patterns I have are along the lines of: [(set (f16 RF16:$dst), (fround (f32 RF32:$src)))] or: [(set (v2f16 VF16:$dst), (fround (v2f32 VF32:$src)))] and these now produce the errors: error: In CONV_f32_f16: Type inference
