strange strsplit gsub problem 0 is this a bug or a string length limitation?
I was working with the rmetrics portfolioBacktesting function and dug into
the code to try to find why my formula with 113 items, i.e. A1 thru A113,
was being truncated and I only get 85 items, not 113.
Is it due to a string length limitation in R or is it a bug in the strsplit
or gsub functions, or in my string?
I'd very much appreciate any suggestions

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.
Thank you,
Andrew

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

Rcmdr GUI goes into loop via alt+backspace under Windows OS
I'm using Rcmdr version 1.4-10 with R version 2.9.0 under Vista x64.
A standard editing convention under Windows is that alt+backspace is a
keyboard shortcut for "undo". I often find myself hitting the [alt] and
[backspace] keys while editing scripts in Rcmdr. However, this causes the
Rcmdr GUI to go into a crazy mode where the menu keeps flashing and the GUI
is unresponsive.
