R devel - Feb 2007 - MCMC Pack Crashes R-GUI session (PR#9516)

Dear Andrew,

I am trying to learn gibbs sampling and Metropolis. 
When I run your gibbs version of multiple linear regression my session crashes.
I have trimmed the dataframe and set my object.size = 1 gigB.
Despite my best efforts it still crashes while advising me to contact the MCMC
Pack developement team.

I am running windows XP with R version 2.4.1.c (the latest).

Here's the offending instruction in R:
 
mcmcReg<-MCMCSVDreg( jpMorganChase.Adj.Close ~
exxon.Oil.Volume+usSteel.Volume,
data=yy.lo.res.scaled[ 2000:2274, ], burnin = 100, mcmc = 1000,

thin=1, verbose = 1, seed = NA, tau2.start = 1,

g0 = 0, a0 = 0.01, b0 = 0.01, c0=2, d0=2, w0=1,

beta.samp=TRUE, intercept=TRUE )



Here's the error msg:

Runtime Error!

Program ... \R\R-2.4.1rc\bin\Rgui.exe

This application has requested the Tuntime to terminate it in an unusual way.
Please contact the applications support team for more information



R Console - Rgui.exe - Application Error

The instruction at "0x5ad71531" referenced memory at
"0x00000014". Memory could
not be read.



Then, it crashes. 



Sincerely,



Lloyd Lubet
