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 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.

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

Can anyone give advice how to interactively exchange data between R and SQL-Databases like DB2, ORACLE, MS-SQL-Server ? If the answer is: 'currently not', this would be information for me as well.

Dear R Gurus, I would very much appreciate some help with this code snippit from my RODBC package. R crashes or exhibits bizarre behaviour when repeatedly fetching large numbers of rows. Examples: > odbcFetchRows(0,max=50000)->xx > odbcFetchRows(0,max=50000)->xx > odbcFetchRows(0,max=50000)->xx > odbcFetchRows(0,max=50000)->xx > odbcFetchRows(0,max=50000)->xx 3rd

I have just finished a first rough cut of RODBC, a database connectivity addon. In theory it should allow access to any odbc compliant database for which the driver set is installed. On unix this includes MySQL, mSQL and postgres using the unixODBC set. On windows it should include access, sqlserver etc if the odbc drivers are installed. For those who have never taken an interest in this,

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

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 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

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,

Full_Name: David Whiting Version: 2.1.0 Under development (unstable) OS: linux Submission from: (NULL) (82.39.106.169) I have just upgraded from a previous version (2.0.0?) and found some of my code that used okay to run now gives an error. The function being called is sqlSave(). I am pretty sure (but not 100% certain) that the data frame I am trying to save has not changed. I am 100% sure that

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

Ok, I''ve found a minor problem that I was able to fix, but I''m not sure if this is the right way to handle it, being new to swig and all. Basically, in wxDC.h, there''s a function declaration: void GradientFillLinear(const wxRect& rect, const wxColour& initialColour, const wxColour& destColour, wxDirection nDirection = wxEAST); The problem is

Anyone out there using Linux RODBC and unixODBC to connect to a Microsoft SQL server? If possible can someone post a sample .odbc.ini file? I saw a few discussions on the archives a few years ago, but no config file details were available. Thanks, Whit This e-mail message is intended only for the named recipient(s) above.

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

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]]
