[Rd] 2 bugs in max.col() (PR#9542)
Dear R-Developers, I think I found two bugs in max.col(). Ties between zeros are not broken, which might affect simulations. -Inf and Zero can be treated the same, which can give completely wrong results, e.g. when the second max is sought by replacing all maxs by -Inf. To fix max.col I do offer the C-code behind my function rowMax(), which also handles NAs and seems to be faster. However, since max.col() is widely used and since I only occasionally program C, I'd appreciate if someone would do code-review and (again) thorough testing before publishing it. Please note that the code was developed under R 1.6.2 and might need porting to R 2.4.1 . Best regards Jens Oehlschlägel # -- output of max.col under 2.4.1. > x <- rbind(c(1,1), c(0,0), c(-Inf, 0), c(0, Inf), c(0, NA), c(NA, 0)) > rownames(x) <- paste("c(", apply(x, 1, paste, collapse=","), ")") > x [,1] [,2] c( 1,1 ) 11 c( 0,0 ) 00 c( -Inf,0 ) -Inf0 c( 0,Inf ) 0 Inf c( 0,NA ) 0 NA c( NA,0 ) NA0 > > cat("ties not broken for c(0,0)\n") ties not broken for c(0,0) > cat("erroneously ties broken for c(-Inf, 0)\n") erroneously ties broken for c(-Inf, 0) > tmp <- sapply(1:10, function(i)max.col(x, > ties.method="random"));rownames(tmp)<-rownames(x);tmp [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] c( 1,1 ) 212211121 1 c( 0,0 ) 222222222 2 c( -Inf,0 )211221211 1 c( 0,Inf ) 222222222 2 c( 0,NA ) NA NA NA NA NA NA NA NA NANA c( NA,0 ) NA NA NA NA NA NA NA NA NANA > cat("The following look good\n") The following look good > tmp <- sapply(1:10, function(i)max.col(x, > ties.method="first"));rownames(tmp)<-rownames(x);tmp [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] c( 1,1 ) 111111111 1 c( 0,0 ) 111111111 1 c( -Inf,0 )222222222 2 c( 0,Inf ) 222222222 2 c( 0,NA ) NA NA NA NA NA NA NA NA NANA c( NA,0 ) NA NA NA NA NA NA NA NA NANA > tmp <- sapply(1:10, function(i)max.col(x, > ties.method="last"));rownames(tmp)<-rownames(x);tmp [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] c( 1,1 ) 222222222 2 c( 0,0 ) 222222222 2 c( -Inf,0 )222222222 2 c( 0,Inf ) 222222222 2 c( 0,NA ) NA NA NA NA NA NA NA NA NANA c( NA,0 ) NA NA NA NA NA NA NA NA NANA > version _ platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status major 2 minor 4.1 year 2006 month 12 day18 svn rev40228 language R version.string R version 2.4.1 (2006-12-18) # -- output of rowMax under 1.6.2 > tmp <- sapply(1:10, function(i)rowMax(x, value=FALSE, na.rm=TRUE, > ties.method="random"));rownames(tmp)<-rownames(x);tmp [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] c( 1,1 ) 222212211 1 c( 0,0 ) 112222111 2 c( -Inf,0 )222222222 2 c( 0,Inf ) 222222222 2 c( 0,NA ) 111111111 1 c( NA,0 ) 222222222 2 > tmp <- sapply(1:10, function(i)rowMax(x, value=FALSE, na.rm=TRUE, > ties.method="first"));rownames(tmp)<-rownames(x);tmp [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] c( 1,1 ) 111111111 1 c( 0,0 ) 111111111 1 c( -Inf,0 )222222222 2 c( 0,Inf ) 222222222 2 c( 0,NA ) 111111111 1 c( NA,0 ) 222222222 2 > tmp <- sapply(1:10, function(i)rowMax(x, value=FALSE, na.rm=TRUE, > ties.method="last"));rownames(tmp)<-rownames(x);tmp [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] c( 1,1 ) 222222222 2 c( 0,0 ) 2222222

Re: [Rd] extracting rows from a data frame by looping over the row names: performance issues
The difference is in indexing by row number vs. indexing by row name. It has long been known that names slow matricies down, some routines make a copy of dimnames of a matrix, remove the dimnames, do the computations with the matrix, then put the dimnames back on. This can speed things up quite a bit in some circumstances. For your example, indexing by number means jumping to a specific offset in the matrix, indexing by name means searching through all the names and doing string comparisons to find the match. A 300 fold difference in speed is not suprising. -- Gregory (Greg) L.

I have tested it with MySQL (I don't have Oracle) and it worked without problems. Please test it step-by-step to make sure that your DB is configured properly. Unfortunately RJDBC doesn't pass non-fatal SQL errors back to the user, so connection problems are not easy to debug, but you can try this to show the connection problem: dbCheck = function(url, user='', pwd='') { j = .jcall("java/sql/DriverManager", "Ljava/sql/Connection;", "getConnection", url, user, pwd, check=FALSE) x = .jgetEx() .jcheck() x } and use it like this: > dbCheck("jdbc:mysql://localhost/foo","user","pwd") [1] "Java-Object{java.sql.SQLException: Access denied for user 'user'@'localhost' (using password: YES)}" > > dbCheck("jdbc:mysql://localhost/foo","root","") [1] "Java-Object{java.sql.SQLException: Unknown database 'foo'}" > dbCheck("jdbc:mysql://bar/foo","root","") I'll see if I can provide some more helpful response in the dbConnect for the next release.. > Another question: > I try to compile ROracle and RMysql for windows but i need Rdll.lib > and it need R.exp.

[Rd] non-blocking socketConnection
In an R session I have > c <-socketConnection("localhost", port=6011, blocking=F, server=T, open="w+") After I connect to the server from, say, telnet % telnet localhost 6011 the socketConnection returns and gives a valid c. My problem is as follows : I would expect something like > readLines(con=c, n=1) to return immediately when reading from c non-blocking c, whether there are any contents to be read or not. However, readLines only returns when there is some input to be consumed, ie if in the telnet session I type foo followed by newline. In short, readLines seems to be blocking even though the connection is presumably non-blocking. FYI, A "file" connection does behave as expected, but I do need the socketConnection here.

Re: [Rd] Problem using callNextMethod() in S4
Dear Martin Thank you for this extensive explanation! I hope that I have understood it, but I will realize it as I proceed with my package. Now, my example works as I have expected it to work, great! One problem that I face is lack of extensive explanation of S4 classes, especially with respect to inheritance. (Neither the tutorial "S4 Classes in 15 pages" nor the book "S Programming" are really helpful.) Most of the time I study the code in BioBase and affy, since there are not many packages available using S4 and inheritance. Your explanation below is a good example, how a good S4 tutorial should cover these issues.

[Rd] Periods in package names?
Hi, is it ok to have more than one period in a package name, e.g. aroma.light.bioc? I remember there was once a limitation/a recommendation that one should use at most one period in a package name. I just browsed "Writing R Extensions" (for R v2.4.1) and scanned it for words "period" and "dot", and I cannot find this limitation anymore, but only: "The Package and Version fields give the name and the version of the package, respectively. The name should consist of letters, numbers, and the dot character and start with a letter. [...]" Best Henrik __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
