similar to: can I do this with read.table??

Hi, This report deals with p-values coming from chisq.test using the simulate.p=TRUE option. The issue is numerical accuracy and was brought up in previous bug reports 3486 and 3896. The bug was considered fixed but apparently was only mostly fixed. Just the typical problem of two values that are mathematically equal not ending up numerically equivalent. Consider this series of three 2x2

Hi, I'm wondering if anyone can point me to a function that will allow me to do a ranking that treats ties differently than rank() provides for? I'd like a method that will assign to the elements of each tie group the largest rank. An example: For the vector 'v', I'd like the method to return 'rv' v: 1 2 3 3 3 4 5 5 6 7 rv: 1 2 5 5 5 6 8 8 9 10 Thanks,

Hi, It would be great if someone would add write.delim() as an adjunct to write.table(), just as with write.csv(). I store a lot of data in tab-delimited files and can read it in easily with: read.delim("text.txt", as.is=TRUE) and would love to be able to write it out as easily when I create these files. The obvious setting needed for write.delim() is sep = "\t", but in

Full_Name: Doug Grove Version: R.1.9.1 OS: Linux Submission from: (NULL) (140.107.156.61) I just found that rank() has a 'decreasing' argument that is not documented in its help page. I checked my version of 2.0.0 (original release hence unpatched) and it is not documented there. For curiousity I also went back to version 1.8.1 and checked the function (not the documentation)and at

Hi all, I am currently building an application based on R 1.7.1 (+ compiled C/C++ code + MySql + VB). I am building this application to work on 2 different platforms (Windows XP Professional (500mb memory) and Windows NT 4.0 with service pack 6 (1gb memory)). This is a very memory intensive application performing sophisticated operations on "large" matrices (typically 5000x1500

Hi, I'm trying to understand a behaviour that I have encountered and can't fathom. Here's some code I will use to illustrate the behaviour: # start with some data frame "a" having some named columns a <- data.frame(a=rep(1,3),c=rep(2,3),d=rep(3,3),e=rep(4,3)) # create a subset of the original data frame, but include a # name "b" that is not present in my

Hi I am trying to process tabular data as follows: Data in the input file is of the form genome1 genome2 tree-dist log10escore Genome1 and genome2 are alphabetic. Tree-dist and log10escore are numeric. I wish to extract only those rows from this table where the log10escore is less than -3. data <-read.table(filename); data$log10escore = data$log10escore[ data$log10escore < -3]; I

Dear All, it seems to me that the function read.spss of package foreign changed its behaviour regarding factors. I noted that in version 0.8-8 variables with value labels in SPSS were transformed in factors with the labels in alphabetic order. In version 0.8-10 they seem to be ordered preserving the order corresponding to their numerical codes in SPSS. However I could not find a description of

Hi, I'm having what I believe are OS problems with my installation of R-1.6.0. The machine I'm using was previously running R-1.4.0. The install seemed fine to me. I didn't note an error messages in 'make' or 'make check'. My problem is that I've been running some memory intesive code, and the code that ran under 1.4.0 but won't run under R.1.6.0 (or under

hello,everyone. I have one question: example 1 > x=numeric(0) > y=5 > print(x+y) numeric(0) example 2 > x=numeric(1) > y=5 > print(x+y) [1] 5 why the print(x+y) is numeric(0) at the first example, but the result is 0 at the second example? __________________________________________________ 佈伵伝仮伱佲伔佈G佊伿佅佷仯伃佒佇伖侜伒佢佉伝伨侙佄佫伬伂伝侙佊伿伡侢伾仹伻伵伋伂伌侒佊伿佅佷

I am opening a connection to an apache server sending a get and then I am reading from the socket. All works finde except that I am getting some strange strings disrupting the html e.g. <FON\r\nffb\r\nT COLOR ... \r\na48\r\n \r\nffb\r\n They are not frequent ( a few of them) but of course make live hard. I cant observe them with lynx --source they dont occure. I am trying a workaround

Hi, I'm trying to figure out if there are any packages allowing one to fit mixed models (or non-linear mixed models) to data that includes censoring. I've done some searching already on CRAN and through the mailing list archives, but haven't discovered anything. Since I may well have done a poor job searching I thought I'd ask here prior to giving up. I understand that

without having to check the vector element by element? Thanks a lot! Jason ===== Jason G.

Full_Name: Doug Grove Version: 1.7.0 OS: Linux Submission from: (NULL) (209.31.211.56) Hi, Minor mistake in the documentation on the colSums page. In the ARGUMENTS section it states for 'dims' that: For `col*', the sum or mean is over dimensions `dims+1, ...'; for `row*' it is over dimensions `1:dims'. These two are reversed. Thanks, Doug Grove

dear friends - I have an ordered factor, ID, in a data.frame, labs, and make a table, aa <- with(labs,table(val >150,ID)) - and now the order in the table is according to the alphabetic order in ID, and not as I want it. I have tried adding [order(unique(labs$ID)] but it doesn't help. I have R 2.7.1 on WinXP. Best wishes Troels -- Troels Ring - - Department of nephrology - -

Hi, I just downloaded and installed last nights version of R-patched and decided that I'd set R_BATCHSAVE=--no-save in config.site, which I haven't done before. Since the comment above R_BATCHSAVE in config.site says: ## The default behavior of R if it encounters EOF in batch mode. ## Set this to one of '--save' or '--no-save' depending whether you ## want automatic

I'm looking for a way to efficiently traverse the Metadata structure in reverse, or otherwise find DITypes that refer to another DIType. As an example, say I have a DICompositeType describing a struct. Now I want to find other DITypes containing this type, e.g. a DIDerivedType describing its pointer type, or another struct containing this struct as one of its fields. Is this possible in LLVM

Hi all, I'm sure this is simple but I don't get it. I have a table mytable<-c(rep("Disagree",37),rep("Agree",64)) table(mytable) this gives me Agree Disagree 64 37 but I didn't ask for it to be in alphabetic order. How can I get it in original order? Disagree Agree 37 64 Thanks, Jeff Jeffrey. M. Miller, PhD
