The menu directory won't compile with gcc 3.4.0 because gcc complains that "ebp" cannot be used as a constraint. If preserving ebp is necessary then it will have to be done in the assembler code. Gcc 3.3.3 just seems to ignore the constraint. It didn't do anything special to preserve the register. I also noticed that getnumrows returns the contents of 0x484 which is the

Hello, I'm working with R version 1.5.0 in Windows. I've written a function (SummaryMat, segment below) which uses a loop to repeatedly call another function (PercentsMat, segment below). PercentsMat creates a matrix and adds rows to it each time it is called. I use deparse(substitute(...)) to get the names of the lists sent to PercentsMat to use them as row names in the generated

I am using the library(bigmemory) to handle large datasets, say 1 GB, and facing following problems. Any hints from anybody can be helpful. _Problem-1: _ I am using "read.big.matrix" function to create a filebacked big matrix of my data and get the following warning: > x = read.big.matrix("/home/utkarsh.s/data.csv",header=T,type="double",shared=T,backingfile

Hello, Everyone, how to use "loop" to make the process automatic and fast? When compute each sample, the script type in R almost the same, just the input and output file's name is changed(chr1 change to chr2, chr3,chr4...). The first sample's script like this: >chr1=MEDIPS.readAlignedSeqences(BSgenome="hg19", file="chr1",numrows= )

I''m having a little trouble with understanding how to work out the schematic for some of my classes using ActiveRecord when a file is in my lib directory: Brief example: Here''s the outline of the files in use: ....app ........controllers ............application_controller.rb ............rushing_offenses_controller.rb ........models ............rushing_offense.rb ....lib

Hey Murali, While playing with HDT which uses your menu, I found I can't reach more than 24 rows whereas my screen is 25. set_windows_size() relies on getnumrows() to define the maximum number of possible rows. But regarding to getnumrows() code, it sounds to report "// Actually numrows - 1". On my screen which is 80x25, getnumcols x getrowcols reports 80x24. The

Dear Isabelle, for most of my work I have switched from S-Plus to R, because it is easier to make scripts with due to the better documentation and some other more reasonable implementations. And there was also a cost issue with the S-Plus Server, which is not for free at all. In R I use the its package for time series, which is quite sufficient for my needs. The only problem I encountered was

Hi Everyone, I just need some further help clarifying a custom rake task I''m building and the logistics of how it should be working. I''ve created a custom rake task in libs/tasks called scraper.rake which so far just contains the following: desc "This task will parse data from ncaa.org and upload the data to our db" task :scraper => :environment do # code goes

I have a dataframe of 25 columns and 100,000 rows called ?testdf?. I wish to build a new dataframe, with 14 columns and 100,000 rows. I wish the new dataframe to have the ?trailing 12 column? mean. That is, I want column 1 of the new dataframe to have soemthing like: ?( mean(testdf[,1:12],na.rm=T)? What is the best way to accomplish this?

Hi, I had the following code: testp <- rcorr(t(datcm1),type = "pearson") mat1 <- testp[[1]][,] > 0.6 mat2 <- testp[[3]][,] < 0.05 mat3 <- mat1 + mat2 The resulting mat3 (smaller version) matrix looks like: NA 0 0 0 0 NA 0 NA 0 0 NA 2 0 0 2 NA To get to the number of times a '2' appears in the rows, I was

Dear all, We are trying to clean multiple realizations of a pattern. Erroneous NODATA and spurious DATA occur in the realizations. As we have to do a 1000 realizations for many patterns, efficiency of the code is important. We need to correct the realizations with a 'mask' pattern of DATA/NODATA. We think an ifelse should do the job. Spurious DATA will be simply removed using the

Hi, I've been trying to use the impute2mach function in the GenABEL library. I unfortunately cannot make a working example as when I scale down the files I no longer get an error message.

Hi, I?m new to R but I?m interested in using the fdim package to find the fractal dimension of a dataset. I downloaded the the package from https://cran.r-project.org/src/contrib/Archive/fdim/ and successfully installed it together with xgobi. However, when I try to run the first example, after df <- fdim(mydata,q=0,Alpha=0.3) I get the following error: Error in .C("pointdif",

We are reading big tables, such as, Chemicals <- read.table('ftp://ftp.bls.gov/pub/time.series/wp/wp.data.7.Chemicals',header = TRUE, sep = '\t', as.is =T) I was wondering if it is possible to set a filter during loading so that we just load what we want not the whole table each time. Thanks, -james

Does anyone have something like tapply that is extremely fast for matrices when there is a very large number of levels of the grouping variable? I'm referring to, for example, tapply(x, grouping.variable, function.operating.on.submatrix) where x is a matrix and the submatrix is a subset of the rows of x. The grouping variable's length equals the number of rows of x. -- Frank E
