Hi, folks: I need to generate all 0-1 sequences with given length,say,n=3, the ideal result would be the following matrix: 0 0 0 0 0 1 0 1 0 0 1 1 1 0 0 1 0 1 1 1 0 1 1 1 Any help would be appreciated. -- View this message in context: http://www.nabble.com/How-to-generate-all-permutation-of-0-1-sequences-in-R--tf4704377.html#a13446919 Sent from the R help mailing list archive at Nabble.com.

Hi, I have a scalar valued function with several variables. One of the variables is restricted to be non-negative. For example, f(x,y)=sqrt(x)*exp(y), then x should be non-negative. I need the gradient and hessian for some vector (0,y), i.e., I need the gradient and hessian at the boudary of parameter space. The "numderiv" package does not work, even for f(x)=sqrt(x), if you do

I am migrating an old dovecot 2.2.30 (macOS High SIerra, macO S Server) to a new server with dovecot 2.3.7 (macOS Mojave, macports). To get the data over, I?m trying to do a reverse backup with doveadm between an old and a new mail server, but failing to do so. I?m trying (from the new server, the old server is 192.168.2.67): doveadm -Dv \ -o imapc_host=192.168.2.67 \ -o imapc_user=gerben \

Hi there, I wanted to use RedCloth with my RubyOnRails 3 application, but it seems that RoR uses 1.9.2''s Psych by default as the YAML parser if available, and Psych fails to load the LaTeX entities file: ==================================================================== #ruby -v: ruby 1.9.2p136 (2010-12-25 revision 30365) [x86_64-linux] irb(main):001:0> Dir.pwd =>

Dear R Users. I just discovered today a problem in the use of quotation marks when I'm doing some programs in R. I'm using windows vista environment. The programs that I wrote in the University, made in Windows XP machines run perfectly, but when I run those in my laptop with VISTA, there are many errors. Those errors are due to the type of quotation marks. In the university the quotation

Hi, I am trying to process genomics data and the presence of both characters and integers in an array is giving issues. The following is an example: > a<-array(c(2,2,"X",1:3,2:4),dim=c(3,3)) > b<-cbind(a[,1],a[,2]) With the output being: [,1] [,2] [1,] "2" "1" [2,] "2" "2" [3,] "X" "3" Is there any

In Windows; to have Firefox pass psyn links to the Curse client I use this command: Code: "C:\Program Files\Curse\CurseClient.exe" -url "%1" but when I try to get Linux's Firefox to pass the psyn link to the Curse client running in wine, wine of course assumes that -url and the quotation marks are for it and not the actual Windows command it's meant to run. How do I

Hi there I want to be able to take all the files in a given directory, read them in one at a time, calculate a distance matrix for them (the files are data matrices) and then print them out to separate files. This is the code I thought I would be able to use (all files are in directory data_files) for(i in 1:length(files)) + { + x<-read.table("data_files/files[[i]]") +

Dear all, One of my friends asked me if it is possible to extract actual R function arguments literally (precisely, as strings). The reason is simple. He feels sometimes awkward to attach quotation marks :-). What he actually wants is to pass R command arguments to XLisp subroutines (He has been an enthusiastic XLisp user for a long time and still tends to use R as a wrapper to XLisp). Is it

Dear R People: I'm sure that this is a very simple problem, but I have been wresting with it for some time. I have the following file that has the following one line: CRS("+init=epsg:28992") Fair enough. I scan it into R and get the following: > u [1] "CRS(\"+init=epsg:28992\")" > gsub(pattern='\"',replacement='"',x=u) [1]

I am using read.table to import a text file within R.   There are several "errors" in my text file.  An "extra" quotation mark has inadvertently been included within a few text fields.   e.g. for a pipe (|) delimited text file, I have something similar to this:   1|7|30| "dog" 2|6|25| ""cat" 3|4|20|"" 4|5| 56| "mouse" 5|3|56|

Is there any way to ensure that quotation marks are left as straight quotes and not converted to curly quotes in the \usage and \examples sections when the pdf versions of the docs are created?

Hi R-helpers, I have a character string, for example: "lm(y ~ X2 + X3 + X4)" from which I would like to strip off the leading and trailing quotation marks resulting in this: lm(y ~ X2 + X3 + X4) I have tried using gsub() but I can't figure out how to specify the quotation mark using a regular expression. Alternatively, I would like a function that lets me delete the leading

Dear R users, Let?s say I have 10 models, each named m1,m2,m3..., and I would like to summarize them automatically and simultaneously - e.g., to extract parameter estimates later on from all models; how can I do that? I have tried: x=1:10 #this creates some example data y=rnorm(10) m1=lm(x~y) m2=lm(x~1) sum.lms=function(x)summary(paste("m",x,sep="")) sum.lms(1:2) but

It was working before (as far as I can tell), but I freezed_edge and now... The first time I load this page, it works fine, the second time I get the superclass mismatch, the third time (and any subsequent times ) i get undefined method. I think this means my class is getting loaded twice? my model looks like this: class Quotation < ActiveRecord::Base has_many :price_breaks has_many

Hi I have a matrix of type "character" (strangly) and am trying to apply the function "aggregate" to it, but unfortunately without success. It seems to me that aggregate would work, if I only could get rid of the quotation marks around each item. So for a very simple example which looks as my actual data look (of course here I put the quotation marks on purpose, but I have
