[R] Error when compiling R-2.5.1 / *** [d-p-q-r-tests.Rout] Fehler 1

Hi everyone, I am new to Linux and R - but I managed to build R-2.5.1 from source to use it in Genepattern. Genepattern does only support R-2.5.1 which I could not find anywhere for installation via apt-get or in the Ubuntu Software-Centre (I am using Ubuntu 14.04 (Trusty Tahr) 32-bit) But after

Adam,   You reopened an old thread noting its age, but did you begin at its beginning? Subject: vectorized sub, gsub, grep, etc. Date: Oct 7, 2008 R pattern-matching and replacement functions are vectorized: they can operate on vectors of targets. However, they can only use one pattern and

[R] missing data in R

Hello Mr. FeldesmanI am a master student in biostatistic my thesis about missing values in microarray data, but � can't create any values. � want to create %10, %20,...%90 missing values for all colums in microarray data set . Can you help me any code? thank you for your attention. Asena Ay�a

Re: [R] Clarification on Simulation and Iteration

I am not sure how you are doing this but there is a package on CRAN which implements the Copas model (metasens). I am not sure whether that would help in your modelling. On 01/08/2015 02:36, Christopher Kelvin via R-help wrote: Dear All, I am performing some simulations for a new model. I run

Re: [R] vectorized sub, gsub, grep, etc.

Hi John, So, you think looping over the sub() function with regular expressions disabled is somehow more nuanced? Perhaps you should have specified that you were only interested in sub() function results. Regardless, the original function failed to match the 'a' in 'ab,' which should have

Re: [R] Using R to fit a curve to a dataset using a specific equation

I can get you started, but you should really read up on non-linear least squares. Calling your data frame dta (since data is a function): plot(Gossypol~Damage_cm, dta) # Looking at the plot, 0 is a plausible estimate for y0: # a+y0 is the asymptote, so estimate about 4000; # b is between 0 and

Re: [R] PythonInR. Python script in R with parameters required. Download satellite images from NASA

Magi, is there a reason that you need to run the script via R? If your plan is to download the data via python than then process with R, you might consider using the Rpy2 package to link them. This would allow you to call the downloading code from python and then have python feed the data to R.

Re: [R] missing data in R

Hi Asena, If you already have microarray data, you can simply change some of the existing values to NA (datum Not Available). Say you have a toy 10x10 array containing absolute (initial) values: array_values-matrix(sample(0:400,100,TRUE),nrow=10) # create a 10% missing array

Re: [R] R parallel / foreach - aggregation of results

You can always just pull the last one off the list. When running things in parallel, what does the last one mean? Do you want the last from each of the parallel threads, or just the last one on the list? You might want to put some flag on the data being returned so you can determine which one

Re: [R] R parallel / foreach - aggregation of results

Dear Jim, Thank you very much for your response. It seems to work now, but the return value is not the required matrix but a list of matrices (one for each repition j). Any idea how it is possible to return only the last matrix and not all? Thanks and best, Martin     Gesendet: Freitag, 31.

Re: [R] R parallel / foreach - aggregation of results

If you return just the row that the foreach procedure produces instead of the entire matrix containing that row and use .combine=rbind then you will end up with the matrix of interest. E.g., Simpar3a - function (n1) { L2distance - matrix(NA, ncol = n1, nrow = n1) data - rnorm(n1)
