Re: [R] Rcmdr GUI goes into loop via alt+backspace under Windows OS
Robert, Alt+Backspace is a standard global shortcut key shortcut key for most Windows programs (Word, Excel, Visual Studio, Notepad, Wordpad. It is equivalent to Ctrl+Z It has been around since at least windows 98: http://www.microsoft.com/enable/products/KeyboardSearch_98.aspx I wished alt+backspace performed the same action under Vista x64, or rang a bell like it does on your machine. Thanks for the feedback. Regards, Andrew Robert Baer wrote: It just produces the bell sound on my 32-bit windows XP machine runing R 2.9.1 Is this really a standard combination?

Re: [R] RODBC results from stored procedure
Thanks Dieter. The stored proc drops and recreates a result table that contains a copy of the same result set that is returned by the query. If I pause after line 1, line 2 returns a valid result set and line 4 displays a table of data. If I do not pause the script after line 1 or 2, line 3 fails, saying datatable does not exist (line 1 query has not completed the recreation of datatable) and line 4 displays no data. Also, the query in line one returns a single result set, a select statement from datatable, but R doesn't see this returned result set after invocation of only line 1. 1.) dbdata-sqlQuery(conn,sp_GetData) #returns a result set in query analyzer, not in R 2.) head(dbdata) #it's empty 3.) dbdata-sqlQuery(conn,select * from datatable order by Date asc) 4.) head(dbdata) #the data is in dbdata My workaround is to run line 1's query manually before running any R scripts. Not ideal, but I'm at a loss for what else to try for this prickly case. Warm regards, Andrew Dieter Menne wrote: tradenet wrote: Thanks Dieter. The date argument isn't a problem.

[R] RODBC results from stored procedure
Short of uploading a SQL server database, I don't think I can make this example reproducible, but I hope it's not so complicated as to require reproducibility I'm using RODBC to get data from Microsoft SQL Server. I can call a parametrized stored procedure without a problem and the proc does indeed execute successfully. However, even though the proc returns the results I found that I had to modify the proc so that, in addition to returning the results to the caller, it also saved the results to an actual SQL Server table. Then I was able to make second call to sqlQuery with a simple select statement for the results table and retrieve the results back into R. My question is: can I get stored proc results directly back to R without having to populate and query a results table? dbdata-sqlQuery(conn,sp_GetReturns,'2009-07-10','2009-07-14') head(dbdata) character(0) [no data here] dbdata-sqlQuery(conn,select * from returns order by Date asc) [...success...] Date Asset1 Asset2 2009-07-10 0.010.02 2009-07-13 0.007 -0.003 ...

Re: [R] strange strsplit gsub problem 0 is this a bug or a string length limitation?
Thanks Marc! I just found that the ~500 char limitation via an online search for the specs for the formula class The rmetrics library I'm using get's it's character array of assets by parsing a formula passed as an input parameter to the portfolioBacktest function. Can I copy the portfolioBacktest function from the source, call it portfolioBackest_hack, add an additional pamater, an array of asset names, and have my version use this argument instead of parsing the formula? I'm fairly new to R so I don't know if R will find my function and if my function will find the other fPortfolio functions that may be referenced by the original, non _hack version of the function.

Review the Note in ?as.character: as.character truncates components of language objects to 500 characters (was about 70 before 1.3.1). It is not a string length limitation or a bug in strsplit(): paste(A, 1:113, sep = , collapse = + ) [1] A1 + A2 + A3 + A4 + A5 + A6 + A7 + A8 + A9 + A10 + A11 + A12 + A13 + A14 + A15 + A16 + A17 + A18 + A19 + A20 + A21 + A22 + A23 + A24 + A25 + A26 + A27 + A28 + A29 + A30 + A31 + A32 + A33 + A34 + A35 + A36 + A37 + A38 + A39 + A40 + A41 + A42 + A43 + A44 + A45 + A46 + A47 + A48 + A49 + A50 + A51 + A52 + A53 + A54 + A55 + A56 + A57 + A58 + A59 + A60 + A61 + A62 + A63 + A64 + A65 + A66 + A67 + A68 + A69 + A70 + A71 + A72 + A73 + A74 + A75 + A76 + A77 + A78 + A79 + A80 + A81 + A82 + A83 + A84 + A85 + A86 + A87 + A88 + A89 + A90 + A91 + A92 + A93 + A94 + A95 + A96 + A97 + A98 + A99 + A100 + A101 + A102 + A103 + A104 + A105 + A106 + A107 + A108 + A109 + A110 + A111 + A112 + A113 nchar(paste(A, 1:113, sep = , collapse = + )) [1] 680 strsplit(paste(A, 1:113, sep = , collapse = + ), \\+ )[[1]] [1] A1 A2 A3 A4 A5 A6 A7 A8 A9 [10] A10 A11 A12 A13 A14 A15 A16 A17
Re: [R] strange strsplit gsub problem 0 is this a bug or a string length limitation?
Thanks Marc. I forwarded the suggestion to Dr. Wuertz and Dr. Chalabi at Rmetrics. Warm regards, Andrew Borden Marc Schwartz-3 wrote: On Jul 10, 2009, at 9:07 AM, tradenet wrote: Thanks Marc! I just found that the ~500 char limitation via an online search for the specs for the formula class The rmetrics library I'm using get's it's character array of assets by parsing a formula passed as an input parameter to the portfolioBacktest function. Can I copy the portfolioBacktest function from the source, call it portfolioBackest_hack, add an additional pamater, an array of asset names, and have my version use this argument instead of parsing the formula? I'm fairly new to R so I don't know if R will find my function and if my function will find the other fPortfolio functions that may be referenced by the original, non _hack version of the function. Warm regards, Andrew Hi Andrew, Happy to help. In terms of your proposal as a short term fix, it may be possible to do that. If you do create a new local function and call it directly, it will be seen instead of the package default version of the same function. However, without reviewing the code and package in detail, you have to be careful about other function dependencies and namespace issues that may be present. I would go ahead and try it to see it it works. A better and longer term approach would be to have the function author(s) modify the way in which they manipulate the formula object. They may wish to review this thread from 2001: https://stat.ethz.ch/pipermail/r-help/2001-August/014628.html Back then, the as.character() limit was 60 and was increased by Prof. Ripley to 500 in response to that discussion. However, in that thread, Prof. Ripley also proposes a better way of manipulating the formula object passed to the function. That approach uses deparse() rather than using as.character().

[R] getting a timeseries element into a string
I have a timeseries object, ts, and want to get the first date in the series into a string so I can concatenate it with a SQL query. Input and output are shown below. I must be missing something very basic, but I can't seem to pry the data (2008-07-01) into a string variable. Any suggestions would be appreciated.
