lpSolve space problem in R 2.4.1 on Windows XP
...ing a standard lp with 2843 variables and 5683
constraints.
I have been able to get the full MIP formulation to work correctly on some
very small problems (~10 variables and 25 constraints).
Here is the code for a working example:
>library(lpSolve)
>(v1=rev(1:8))
[1] 8 7 6 5 4 3 2 1
>(csv1=cumsum(as.numeric(v1)))
[1] 8 15 21 26 30 33 35 36
>(lencsv1=length(csv1))
[1] 8
>(Nm1=lencsv1-1)
[1] 7
>(Np1=lencsv1+1)
[1] 9
>ngp=3
>f.obj=c(1,1,rep(0,Nm1))
>f.int=3:Np1
>bin.con=cbind(rep(0,Nm1),rep(0,Nm1),diag(Nm1))
>bin.dir=rep("<=",Nm1)
>bin.rhs=rep(1,...

Read function that detects format automatically
...uman statistican easy to
see the format of the file by looking at a fragment, so it should be
possible to capture these rules in some code. It would be nice to have
something like a read.magic() function that reads a datafile using the
appropriate command, regardless of whether the user supplied an csv1, csv2,
tab delimited, excel, spss, stata, etc file.
I actually started to code something like this, but then I figured that
maybe someone else has had the exact same idea.

zpool import hangs indefinitely (retry post in parts; too long?)
Now at 36 hours since zdb process start and:
PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP
827 root 4936M 4931M sleep 59 0 0:50:47 0.2% zdb/209
Idling at 0.2% processor for nearly the past 24 hours... feels very stuck. Thoughts on how to determine where and why?
