How to save a complete image of the current state of R ?
Hello, I like to save the complete state of R, i.e. including all environments, objects/workspaces, loaded packages etc.. This wish has arisen since I am not able to reproduce an error which occurs when running R CMD check. Many thanks for your advice in advance. Best Regards Andreas

bug or feature? (PR#4150)
Full_Name: Axel Benz Version: 1.7.1 OS: Windows Submission from: (NULL) (137.251.33.43) This feature seems to be a basic bug: > 1=="1" [1] TRUE > as.numeric(1)=="1" [1] TRUE > as.numeric(1)==as.character("1") [1] TRUE isn't it necessary to distinguish beteen numbers and characters??

write.table row.names and col.names (PR#2610)
Full_Name: Wolfgang Huber Version: 1.6.2 OS: DEC OSF, Win, Linux Submission from: (NULL) (155.52.45.139) When data.frames are written to a file using write.table and with row.names and col.names, then the colnames are displaced by 1 with respect to column content. Example: > x = data.frame( > obscht=c("chriesi", "bire"), >

Critical Bug in type conversions: as.integer, trunc, ... (PR#8255)
Full_Name: Grischa T?dt Version: 2.1.1 OS: windows XP Submission from: (NULL) (192.108.25.32) I have a strange behaviour in R, looks like type conversions are messed up. To reproduce: expected: > typeof(3) [1] "double" > as.integer(3) [1] 3 !!!! strange: > typeof((0.3/0.1)) [1] "double" > as.integer((0.3/0.1)) [1] 2 also for trunc: >trunc(c(5,7))

Wish list
This is my New Year wishlist for R features. One common thread is that I find I sometimes use languages other than R including javascript, Windows batch and gawk. Others have mentioned other languages too. It would be nice if, in those cases I could use R simplifying development into a single environment (viz. R). The following are not in any order. 1. Self Contained Executables Make it

Repeated Measures MANOVA in R
Can R do a repeated measures MANOVA and tell what dimensionality the statistical variance occupies? I have been using MATLAB and SPSS to do my statistics. MATLAB can do ANOVAs and MANOVAs. When it performs a MANOVA, it returns a parameter d that estimates the dimensionality in which the means lie. It also returns a vector of p-values, where each p_n tests the null hypothesis that the mean

Graphic parameters with length zero in grid cause R to crash
Hi, I found in grid package, if the graphic parameters have zero length, R crashes. In the following code, I only tested `grid.rect()` and the `fill` parameter, but I think it should be similar as other grid graphic functions. In `gpar()` function, the graphic parameters are not allowed to have zero length, but we can make them with zero length by first generating a `gpar` object and then

dimnames returned by function apply
Dear all, I noticed that the dimnames returned by apply are different in the new release. In the following example. The returned row-names are c(?S?,?T?), but shouldn?t they be c(?X?,?Y?) as in the old release? Best, Bernd >X = array(1:8, dim=c(4,2)) >dimnames(X) = list(c("A","B","C","D"),c("S","T")) >apply(X, 1, function(x)

Light-weight data.frame class: was: how to add method to .Primitive function
Hi, Encouraged by a tip from Simon Urbanek I tried to use the S3 machinery to write a faster version of the data.frame class. This quickly hits a snag: the "[.default"(x, i) for some reason cares about the dimensionality of x. In the end there is a full transcript of my R session. It includes the motivation for writing the class and the problems I have encountered. As a result I see

Dimensional reduction package
Is there any R package which implements non-linear dimensionality reduction (LLE, ISOMAP, GTM, and so on) and/or intrinsic dimensionality estimation ? Thank you, Maura tutti i telefonini TIM! [[alternative HTML version deleted]]

RODBC and 64 bit
Hi all, I was quite succesfully working with the RODB package on a 32 bit linux box to connect to a MSSQL Server via the freeTSL driver. After changing to a 64 bit environment I ran into some segmentation faults using function sqlUpdate on large database operations (the actual seg faults occured in the call to the C function ODBCUpdate). I just briefly looked into the code and found some extensive

operating on arrays of unknown dimensionality
Dear R-users, I am looking for a way to assign to slices of arrays where dimensionality of the array is not a-priory known. Specifically, I would like to be able to generalize the following example of dimensionality 2 to an arbitrary diminsionality: In this example we create an array x, a smaller array y and then assign y to a slice of x. > dimnmx <- list(c('a','b'),

GSoC 2017 Project Proposal
Hello devs. I would like to propose how I plan to go about improving and getting a system that can be integrated into Xapian in this GSoC for the clustering branch. I have identified three areas of work which were not touched last time. 1) Automated Performance Analysis I had roughly implemented 2 evaluation techniques previously (Distance b/w document and centroids within clusters and

r data structures
hi, i'm trying to understand r data structures. i see that vectors, matrix, factors and arrays have a "dimension." there seems to be no mention of dimensionality anywhere for lists or dataframes. can i consider lists and frames to be of fixed dimension 2? thanks, jay s

Testing for vectors
Hi all, Is there are base function that I've missed that tests if an object is a vector in the dimensionality sense, rather than the data structure sense? i.e. something that checks is.null(dim(x)) ? is.vector() is trivially disqualified since it also checks for the presence of non-names attributes: x <- factor(c("a", "a", "b")) is.vector(x) #> [1] FALSE
