similar to: Strange behaviour of type conversion (PR#8256)

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))

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)

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"), >

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

Full_Name: Andreas Buness Version: 1.7.1 OS: Unix Submission from: (NULL) (193.174.53.122) I would like to ask you to enhance the apply function with an option drop=FALSE similar to the one existing for subsetting of arrays. Or any other mechanism to get control on the dimensionality of an object resulting from an apply call. This could facilitate more robust programming.

Hello! I'm not sure if is it a BUG or not... I'm using R 1.9.0, and I used the command below: > is.integer(9) [1] FALSE R manual contains this words about the is.integer() function: "is.integer returns TRUE or FALSE depending on whether its argument is of integer type or not." What's the problem? Am I wrong about the BUG report? Thank you very much. M?rcio de

Hi all; Is it possible to modify the "@" operator that it can handle references (or external pointers) of S4 Object instead of the real Objects? Or is there any technical or compatibility issue which make it impossible? I look forward to hear from you and also hope that you don't hate me for my nooby question. Yours sincerely, Rudolf Biczok [[alternative

Has anyone running R 1.8.1 on a 64 bit system gotten negative numbers from object.size() on objects > 2GB or so? For example, on Solaris/Sparc I get > b <- numeric(131072 * 2800) > object.size(b) [1] -1358954440 I get similar behavior on the Opteron (SuSE Linux). I'm not sure if this is an R problem or something wrong with the way it was compiled on either system. I

In R-devel, the Depends: field in the DESCRIPTION file is now used by library() to load the named packages before the current package, and also to set up the environment to save images and prepare for lazy loading. Would authors please use a minimally necessary set of packages in Depends, and put others in Suggests: -- the distinction is made in `Writing R Extensions'. On the other hand,

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?? Best Regards, Axel

A professor here at Vanderbilt sent me the following code. Each of the text strings should right justify against the center vertical bar, but because of font issues it doesn't. I understand that there are workarounds, but I was just curious if this was consistent across all platforms. On linux with R 2.7.1 and R-trunk (r46103), both acrobat reader 8 and kpdf render it incorrectly. How

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

I have a problem, that the plot of mathematical formula sometimes crashes R on Linux (SuSE 6.2 and 7.0 on a Dual PIII/500 machine with 1GB RAM). The problem occurs for example in demo("graphics"), i.e. in the last part were the mathematical symbols are plotted. There are several circumstances to reproduce this segmentation fault, but the following is one of the most simple examples. The
