Hi, I am running simulations that does multiple comparisons to control. For each simulation, I need to model 7 nls functions. I loop over 7 to do the nls using try if try fails, I break out of that loop, and go to next simulation. I get warnings on nls failures, but the simulation continues to run, except when the internal call (internal to nls) of the chol2inv fails.

Hi, I have a loop as follows, dataStr <- character(0) repeat{ fstr<-read.socket(sockfd) if(fstr=="") break dataStr<-paste(dataStr,fstr) } at what point does dataStr stop accepting(gets full)? I'm sending millions of records over the socket and need to know if all of it can go into dataStr. Also, Incase all of it cannot go into dataStr, I need to parse each

I''ve spent hours researching the subject and have tried many test sequences in IRB, and rails console but I''m just having trouble making headway into what is probably a very easy subject. I understand arrays with at least 4 other languages but with Ruby I haven''t found a mental connection with how I can assign variables to arrays.. Take for example: def

Dear all, when trying to replicate John M. Quick's example for correlations between multiple variables posted on: http://rtutorialseries.blogspot.com/2009/11/r-tutorial-series-zero-order.html with R 2.11.0 (GUI 1.33) using my MacBook Pro with OX X 10.5.8 I got the following error message > datavar<-read.csv("dataset_readingTests.csv") > cor(datavar) Error in cor(datavar)

How best to implement a decorator pattern in R? What I mean, why I ask: A group of ncdf4 users is trying to make it easier (notably for ourselves :-) to write correctly IOAPI-formatted netCDF. Since IOAPI http://www.baronams.com/products/ioapi/ decorates netCDF, one obvious way to do a package=ioapi is to decorate the netCDF API from package=ncdf4. E.g., to add a data variable (datavar) with

Hello, My question likely got buried so I am reposting it in the hopes that someone has an answer. I have thought more about the question and modified my question. I hope tha my specific question is: I am attempting to create a bootstrap procedure for a finite sample using the theory of Rao and Wu, JASA (1988) that replicates within each strata (h) n_h - 1 times. To this end, I require a

SUMMARY: Specific problem: I'm regridding biomass-burning emissions from a global/unprojected inventory to a regional projection (LCC over North America). I need to have boundaries for Canada, Mexico, and US (including US states), but also Caribbean and Atlantic nations (notably the Bahamas). I would also like to add Canadian provinces and Mexican states. How to put these together? General

Hi, I encountered a problem when I am trying to write my own function which contains another function. To simplify a problem, I tried the following simplified function, hope someone can idenfity the problem for me. I have a simple data frame called "testdata" as following: >

Hi everyone, I understand the process of obtaining the internal integer codes for the raw values of a factor (using as.numeric() as below), but what is the best way to obtain these codes for the levels() of a factor (since the as.numeric() results don't really make clear which code maps to which level)?

I have got a list named "filtered", I would like to construct alist named "fdata" as following: fdata <- cbind(matrix(unlist(filtered),ncol=28), myregime) If I try names(filtered), it gives all the correct name for each vector, but if I try names(fdata), it appears "filtered[[1]]" "filtered[[2]]" ..., How can I keep the name in "fdata"?

Hi Guys, I would like to weight column entries in a data frame by the population of each state. For example, here is some data: state statenum year income popul ALABAMA 1 1 9.703193 3973.00 ALABAMA 1 2 9.745950 3992.00 ALABAMA 1 3 9.762092 4015.00 ALASKA 2 1 10.221640 532.00 ALASKA 2 2 10.169600

Hi All, I have a problem with rbind. I have data that consist of weight height .. etc of 1000 patients.

Hi there, When I compile my code with -fdata-sections and -ffunction-sections, I still see some unused string in my shared library (Android). Actually, the strings appear together inside a .rodata.str1.1 section instead of getting their own section. It seems that the C-string literal are considered differently than other constant and the -fdata-sections is not respected in

Then how about enable these flags for -O2? I want to hear from other people cc'ed, and I may be too cautious, but I'd hesitate to define a new ELF section if there's other mean already available to achieve the same thing.

Is there any reason -ffunction-sections and -fdata-sections wouldn't work? If it'll work, it may be be better to say "if you want to get a better linker output use these options", rather than defining new ELF section.
