similar to: application of R

Thank you very much this really helped me a lot . So actually why would people learn R(other than personal interests ) if you can't really build anything that can be sold ?

Because many technical people need to accomplish statistical data analysis with computers that depend on existing algorithms applied in new ways, or with new algorithms that are not implemented by commercial software. Often such people have no desire to provide step-by-step support of their tools for every user of their code indefinitely, so developing commercial software for others is less

Oh I see thank you very much now I understand. So for me as I am considered an intermediate in R and also C++ what kind of programming language I could take up and learn to make a commercial statistical software ? Any advices as well ? > On 12 Jan 2018, at 12:40 PM, Jeff Newmiller <jdnewmil at dcn.davis.ca.us> wrote: > > Because many technical people need to accomplish statistical

Dear all, I want to draw ticks on the 3rd and 4th row of a lattice. How do I do this ? In my search of the help, I discovered a parameter alternating,which kind of says where the ticks will be but does not suffice for me. I am running this command : - barchart(X03/1000~time|Company, data=df1[which(df1$time!=1),], horiz=F,

Is R file IO slow in general or am I missing something? It takes me 5 minutes to do a load(MYFILE) where MYFILE is a 27 MB Rdata file. Is there any way to speed this up? The one idea I have is having R call a C or Perl routine, reading the file in that language, converting the data in to R objects, then sending them back into R. This is more work that I want to do, however, in loading Rdata

hi everybody, anyone knows how we can transform a binary matrix with TRUE and FALSE to 0 and 1 without looping? Thx --------------------------------- [[alternate HTML version deleted]]

Hello all, We are experiencing problems using MYOB Premier V6.0.2 on Windows 2000 computers SP3, with the data file residing on shared drive on Linux (Redhat 7.2) file server running Samba Version 2.2.1a and kernel 2.4.9-34. The MYOB Tech support have told me that it is a problem with our network but could not give me any hints where the problem might be. The MYOB database has been corrupted

Hello, I want to use lme to fit two (or more) models, and then compare the fits on each individual. I know how to write my own code to do this (for each individual, plot the raw data, followed by lines() to plot each fitted curve) but I would like to use plot(augPred(... as it produces a nice trellis plot. I thought I could do this with par(new=T) but it does not seem to work.

Is the following a bug with stem() or is there something else that I am missing? I ran stem() on the vector x below and got stem(x-10) instead of stem(x). If I subtract 1 from x, I get a correct answer. If I add 1 to x, I still get a wrong answer. If I add 10 to x, I get a correct answer. I'm not sure what to make of this, other than to think it is a bug. Can anyone tell me if this is a bug?

I'm doing these manipulations on the data frame and wondering why does R have to remember historical data on my operation and not just keep the needed info. Probably a basic fundamentals of the way R handles data .. Pls point me to the manual if possible .. I have this Index data: > head(NIFTY_INDX) Constituents.list.of.S.P.CNX.Nifty X X.1 X.2 X.3

Dear all, there are R packages able to simulate or estimate bilinear model for time series? I know it is an open problem, but do exist something for very simplified bilinear models? Alternatively, what kinfd of non linear time series models are performed in R? If R is not able, could someone suggest me for some commercial softwares to deal with bilinear models? i'm afraid of a negative

Hi I'm getting started with R and i have difficulties finding how to solve this problem in R : Find x,y satisfying Trace(K) < C, K positive where ( K=x.A+y.B), [A,B,K square Matrix in R(n x n), x,y in R] Thanks in advance, Ramzi [[alternative HTML version deleted]]

Hi all, and thx a lot for your answers, in fact i know that R deals with logical numbers 0 and 1 the same way like TRUE and FALSE but my problem is in fact with C language. I have done an interface with C and my first problem was with float variables, but this warning doesn't appear everytime and really i don't know the problem with R: "Warning message: DLL attempted to change

Hi I'm processing sequencing data trying to collapsing the locations of each unique sequence and write the results to a file (as storing that in a table will require 10GB mem at least) so I wrote a function that, given a sequence id, provide the needed line to be stored library(doMC) # load library registerDoMC(12) # assign the Number of CPU

Dear all, i was working under R 1.6.2 but i wanted to install bioconductor under WinXP, and because R 1.7.1 contains the TclTk package and automatic installation of bioconductor packages, so i install it.

HI Helpers, How could we use R and R packages licensed under GPL into commercial products? Is it allowed to load a library and get the results from it and using the results for commercial use? Thank you so much! Regards, Yan [[alternative HTML version deleted]]
