Some days ago I asked for general methods to access SQL-Databases. Thanks to: Terry Westley [twestley at buffalo.veridian.com], partha_bagchi at hgsi.com, F.Tusell [etptupaf at bs.ehu.es], Michael Lapsley [mlapsley at ndirect.co.uk], Robert Gentleman [rgentlem at jimmy.harvard.edu], Torsten Hothorn [hothorn at statistik.uni-dortmund.de] Several solutions were suggested: (1) using Michael

Dear developers, I wonder would you consider making a save to a graphics file format (as opposed to ps)? What prompts this is that we have just finished my wife's thesis using R heavily for stats and graphs. The combination of latex, bibtex and R generated .eps worked a treat and we were very pleased with both the final outcome and the efficiency of gernerating it, especially when all the

Here is another of those 'is it a bug or am I using it wrong' questions: I'd be very grateful if someone could help. I am doing a lot of graphs for a thesis at the minute, many of which need (ideally) greek letters in xlab and ylab. This works: >plot(c(1,2,3,4),c(1,2,3,4),xlab=expression( alpha * "-1-m")) > This does not: >

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 tabl...

Dear R-helpers, I wonder if I could impose upon you for forther assistance, this time with dataframes: hopefully this will be of general interest, as I personally have found them hard to get to grips with. I was trying to transpose rows and cols and move col1 to the names. Then all sorts of things go wrong. Although the end result looks the same, page() shows the structure to be quite

Would anyone care to comment if this is the best solution to this problem? > trygrep <-function(x,y) + if(grep(x,y)) + print("yes") else + print("NO") > >trygrep("foo","bafoobar") [1] "yes" > > trygrep("foo","bar") Error in if (grep(x, y)) print("yes") else print("NO") : missing value

Dear list, What is the correct approved way to abort a library install if the c fails to build? I am tarting up my odbc library, and I would like to stop the install process if the needed header files and libraries are not present on the system. Error messages flash past so fast that it is easy to miss their significance. Michael ---------------------------------- E-Mail: Michael Lapsley

Dear, I am now writing more formal "academical" paper, and would like to reference an R package. Do you have any recommendation how to do it? Taking for instance the RODBC package as an example, how would the reference look like? http://cran.r-project.org/web/packages/RODBC/index.html Thank you Jan [[alternative HTML version deleted]]

Here is a nasty one: (0.65.1 on linux) > plot(c(1,2,3,4),c(2,4,6,8),log="Y") Segmentation fault (core dumped) [ml at athome ml]$ Seems the bug is in errorcall(). yes, I know the syntax is wrong, but it is an easy mistake to make and it is inconvenient to lose the work space at times.

Firstly can I add my congradulations to the R core team on the release of v1.0.0 and my thanks for all their hard work. To the subject of this message: does anyone have a binary version of Michael Lapsley's RODBC package built for win32 that they can distribute? I have a solution where I can use Perl ODBC functions to dump data to a text file for reading in to R, but I think the direct ODBC

I saw in the R-digest a thread about RODBC. 1) I think that this package is *extremely* valuable : it fulfills a need quite important in the case of iterative (e. g. periodic) analyses. No need to periodically return to your data and re-dumping them ... 2) The current version has a serious bug if your datasets has missing numeric values. M. Lapsley, the original author, is aware of it, but has

There is a new version of RODBC, 0.9-1, with a new maintainer (me) now on CRAN (Vienna) which works with R 1.6.x. The Windows binary will be there tomorrow, and both will then propagate around CRAN. This has been tested on Linux under unixODBC against MySQL and Postgresql (thanks to Dirk Edelbuettel), and on Windows against Access, MySQL and Excel. The CRAN compilation checks were against

Dear lists, It seems that RODBC has a problem : when reading through ODBC from an Access table with missing values, *character* missing values are (correctly) reported as NA factor values. *Numeric* values, however, retain the value of the same variable in the previous row. My setup : R 1.1.1 under Win95, RODBC as compiled with the R Win CRAN distribution, MS Access 97. I just discovered this,

On behalf of Michael Lapsley, who is away. There is a new version of RODBC on CRAN, version 0.8-2. A version compiled for rw1011 will propagate to CRAN tonight. Main differences: - This will work with the up-coming R 1.2.0. - Nulls in databases are handled (more) correctly. The bug that has been reported with repeated entries was it transpires to do with null fields, not empty ones

Full_Name: Emmanuel Charpentier Version: R 1.1.1 OS: Windows 98 FE / Linux (Debian 2.2) Submission from: (NULL) (164.2.255.244) This bug report is pro forma. I've already reported it informally on R-help and R-devel. The current (0.7) version of RODBC has a problem with missing values. It correctly gets missing "character" values (as blanks), but puts the last non-missing value of
