CRAN binary, but no source
Hi All,
this is a CRAN question, so I am sorry if this is not the appropriate forum.
I noticed that there is at least one CRAN package that has a binary (OSX
Mavericks) for a version, that does not have any source package on CRAN. Or
at least I am unable to locate it. The package is Rglpk:
http://cran.r-project.org/web/packages/Rglpk/index.html
It offers a binary for 0.5-2, but there is no 0.5-2 source package
anywhere. Is this simply a mistake, or it is OK to have binary-only
packages on CRAN?
Thanks much, Best,
Gabor

regarding Rglpk loading
Hi everybody,
I installed Rglpk package from local zip files. Then I tried to load the
package in a R session. But R shows following message.
Loading required package: slam
Error: package 'slam' could not be loaded
In addition: Warning message:

Rglpk
Hi list,
in the Rglpk_solve_LP function (::Rglpk),
on line 26, the function calls a function
as.glp_bounds() that i cannot access.
i'm trying to alter the Rglpk_solve_LP function
to add a line to retrieve column/row dual values.
everytime i change the slightest line of code inside

Because the latest version failed to build on Mavericks:
http://www.r-project.org/nosvn/R.check/r-release-osx-x86_64-mavericks/Rglpk-00install.html
Possibly because a system requirement is not installed.

Optimization Question
Hi All
Apologies if this is not the correct list for this question.
The Rglpk package offers the following example in its documentation
library(Rglpk)
## Simple mixed integer linear program.
## maximize: 3 x_1 + 1 x_2 + 3 x_3
## subject to: -1 x_1 + 2 x_2 + x_3 <= 4
## 4 x_2 - 3 x_3 <= 2
## x_1 - 3 x_2 + 2 x_3 <= 3
## x_1, x_3 are non-negative integers
## x_2 is a...

minimisation problem, two setups (nonlinear with equality constraints/linear programming with mixed constraints)
...am still looking into some of the options mentioned in the original thread, but I have been advised that there may be better ways if I present the actual problem with a reproducible example.
In principle the problem can be solved by linear programming, so I include code for my attempt at this via RGLPK. It says that there is no feasible solution, but the solution is known analytically in the case below.
Here is the precise problem:
Minimise, over 100?1 real vectors v,
Max_i(|v_i|) such that X'v=e_2,
where X is a given 100?2 matrix and e_2 =(0,1)'. The v_i are the elements of v.

glpk package missing?
...oad and install the glpk package directly from insider the R
program (for Windows), and everything worked fine. Now I have installed
R for Windows on a new computer, and I cannot find the glpk package on
the list of available packages on my local CRAN mirror.
I do see two packages labeled "Rglpk" and "glpkAPI", but as far as I can
understand these just interface with an outside version of glpk, which I
don't have. I also found an old link to R glpk in a Wikibooks page, but
it now says "Package ?glpk? was removed from the CRAN repository."
Is there a reason...

asking advice for Integer Programming packages
Dear everyone,
I don't know much about Integer Programming but am afraid I am facing
a problem that can only be solved via Integer Programming. I was
wondering if those of you who have experience with it could recommend
an R package.
I found the following R packages:
Rglpk
glpk
lpSolve
lpSolveAPI
Are there any others?
Are some of them easier to use than others for a beginner?
Any advice would be greatly appreciated!

CRAN binary, but no source
...wo places to look for such information on CRAN:
- Where a fair amount of information needs to be given (like exactly
which versions have been removed), there may be a README in the Archive
directory. E.g.
http://cran.r-project.org/src/contrib/Archive/sdcTable/README , and I
have added one for Rglpk.
- There is a DCF file http://cran.r-project.org/src/contrib/PACKAGES.in
which acts as the database which R CMD check --as-cran consults. That
contains concise records of archival and removal. Its coverage is
pretty good for the last three years.

Semi continous variable- define bounds using lpsolve
How to define bounds for a semi continous variable in lp_solve.
Min 5x1 +9x2 +7.15x3 +0.1x4
subject to
x1+x2+x3+x4=6.7
x1+x4 <= 6.5
And x3 can be 0 or greater than 3.6
hence x3 is a semi continous variable
how to define bounds as well as semicontinous function because using
set.semicont and set. bound simantaneously doesn't seem to work.Thanks in
advance for the help

Solving graph theory problems with R ? (minimum vertex cover)

My specific problem is called:

a hypergraph <http://en.wikipedia.org/wiki/Hypergraph> (Please see the links
