Hello, ?as.character says that the as.character function is a generic with usage: as.character(x, ...). So, I want to create an S4 object with an as.character method following the above usage, but I get the below error telling me that ... isn't in the generic for as.character. > setClass("tmp", "numeric") > setMethod("as.character", "tmp",

R-Help, I discovered a "mis-feature" is ghostscript, which is used by the bitmap function. It seems that specifying file names in the form "~/abc.png" rather than "/home/directory/abc.png" causes my GS to crash when I open the bitmap device on my Linux box. The easiest solution would seem to be to intercept any file names in the form "~/abc.png" and replace

I was unaware until recently that partial matching was used to index data frames and lists. This is now causing a great deal of problems in my code as I sometimes index a list without knowing what elements it contains, expecting a NULL if the column does not exist. However, if partial matching is used, sometimes R will return an object I do not want. My question, is there an easy way of getting

I'd like to report a bug (buffer overflow?) in the function sub(..., perl = TRUE) I wanted to implement the familiar perl function for removing white spaces before and after a character string: sub trimwhitespace($) { my $string = shift; $string =~ s/^\s+//; $string =~ s/\s+$//; return $string; } So in R this would (presumably) become: trimwhitespace <- function(x) { x <-

Hello all, I'm trying to setup a simple construct that will email me all errors, warnings, and output of a sample R script. My initial thought was to use sink() and tryCatch around the script such that at the end of the script any output would be mailed to me, i.e.: sinkFile <- tempfile() sink(sinkFile) tryCatch({ [R script]}, finally = { sink() if (length(readLines(sinkFile)))

Hi, I found the following on Windows 2000/NT R Version 1.9.1 (2004-06-21) (also Version 1.9.0): The S4 group "Math" doesn't work as documented; i.e., "log", "log10", "gamma" and "lgamma" are included in the documentation but don't work. See example code below. Moreover, what about 'genericForPrimitive' which is used in

Here is a possible BUG with as.data.frame() and/or [.data.frame which broke Michael Lapsleys RODBC-Code. Can anyone confirm it is a bug or a 'feature' of the prototype? tablename <- "abc" a <- as.data.frame(cbind("abc", 1:3)) b <- as.data.frame(cbind(tablename, 1:3)) # ok > a V1 V2 1 abc 1 2 abc 2 3 abc 3 # missing column name > b tablename 1

Hi, I started creating a small class but I'm courious about how it is working. To create a instance of my class "Partri" I write this at Rgui: x <- new("Partri", name="Gilvan") and to change the slot "name" of this instance, I write: setName(x, newname="Justino") It is not working, because when I type "x" at Rgui, it shows

Fixing one bug uncovers the next one... To reproduce: llvm-ar rc ./libgcc.a libgcc/./_muldi3.o <and-lots-more-.o-files...> The result: C:\msys\1.0\home\llvm_home\install\bin\llvm-ar.exe: Can't move './libgcc.a-000003' to './libgcc.a-000002': Cannot create a file when that file already exists. So apparently, we're trying to move one file on top of another. The

Yep, you found another bug. Unlike Unix, Windows does not allow a file to be implicitly replaced via renaming. I'll fix it.

I can report that the computer renaming worked. As it turned out, only the cn was incorrect ... ldbsearch -H ldap://DC1 -UAdministrator 'CN=DT06' dn: CN=DT06,OU=Desktops,OU=Computers,DC=domain,DC=com objectClass: computer cn: DT06 operatingSystem: Windows 10 Pro displayName: WH23$ sAMAccountName: WH23$ ... so a simple LDAP rename worked ... ldbrename -H ldap://DC1 -UAdministrator

I see another thing in function 'NewName' in bind.c. In else if (*CHAR(tag)) , 'ans' is basically copied from 'tag'. Could the whole thing there be just the following? ans = tag; It seems to me that it can also replace ans = R_BlankString; in 'else'; so, else if (*CHAR(tag)) and else can be merged to be just else . --------------------------------------------

Samba Version 4.1.4-SerNet-RedHat-7.el6 Using RSAT via Windows 8.1 -- For a computer that is on the domain, I rename it from the client, then reboot. This renames the computer as expected. The common name in AD, however, is not affected. Is there a way to do this? Am I missing a step? Details: Using RSAT, I see the old computer name, not the new computer name. If I double click on the entity,

Hi, I've looked all over for a solution to this, but haven't had much look in specifying what I want to do with appropriate search terms. Thus I'm turning to R-help. In the process of trying to write a simple function to rename individual column names in a data frame, I ran into the following problem: When I rename the columns within my function, I can't seem to get it to

Hello All! I have been working with R for the last couple of weeks and I am very impressed with the capabilities. I am creating hundreds of tables and need to dynamically name the columns. Here is a small snippet of my code: # Turn my clustering data into a data.frame object. names( clusters ) <- Abbreviate( distMethods[ i ], hclustMethods[ j ] ) df <- data.frame( clusters,

Is it correct (by its lack of mention in the R-Language Definition Manual) that it is impossible to create a user-defined unary operator? Ex: (This doesn't work, but it's an example of what I'm looking for) > "%PLUSONE%" <- function(x) x + 1 > %PLUSONE% 2 [1] 3 And if the above is impossible, am I limited to only the + - ~ ! unary operators for overloading? On

Hi all I'm have a character vector and would like to suppress the blanks if there are more than one after the other. Example: Character value is: "abc def ghi" The result should be: "abc def ghi" I know that it's possible to delete the leading blanks with the command "trim". But how can I delete blanks within a character? Thank you very much in

I frequently get data sets with cryptically-named variables. The datasets are more useful to me with informative variable names. I know that I can rename variables using the following command: dimname(dataset[[2]][index.of.variable.to.be.renamed]<-new.variable.name If I want to do this inside a function (say something I call RenameCol) what is the best way to communicate the

Dear all, Assume that I have an S4 class "MyClass" with a slot "myname", which is initialized to: myname="" in method("initialize"): myclass <- new("MyClass", myname="") Assume that class "MyClass" has a method "mymethod": "mymethod.MyClass" <- function(object, myname=character(0), ...) {
