Re: [R] [R-SIG-Finance] RTAQ - convert function: warning causes incorrect loading of data

2012-10-15 Thread Nicolae Caprarescu
Hello, Thanks for looking into it. What process do people usually follow to fix bugs in RTAQ? I took me a while to realise what's wrong with it, therefore it would be great if we can address it so others won't have to encounter it. Best, Nicolae On Sat, 13 Oct 2012 12:33:01 -0500, Jeff Ryan

My guess would be that your running the 32 bit version of R - and rJava is looking for the 64 bit dll. I'd suggest starting the 64 bit version of R explicitly (e.g. the 64 bit version of Rgui lives at R_HOME/bin/x64/Rgui.exe, whereas the 32 bit version lives at R_HOME/bin/i386/Rgui.exe). On Tue,
