I am interested in implementing firefly algorithm to solve some optimization problems. Since the majority of my work is based on R, I am searching a R package to do it.
Through searching the internet, it is realized that such algorithm is available for "matlab". However, it seems that no package is currently available in R.
Does anyone knows anything or have any suggestion about it?
Thanks in advance for any reply.
Now in R, you can use metaheuristicOpt for implementing firefly algorithm.

I searched at various places but didn't find any relevant packages for this. I need to know how people proceed with FIEGARCH Modelling in any software.
you can use oxmetric or s_pluse software for this work.
This is quite a general question, but I have not been able to find a solution so far.
I am trying to solve a problem of combinatorial optimization in which I have several objective functions to optimize, as well as several constraints to impose. I am thus trying to find some software (an R package preferably) that can solve this problem.
I have explored several options, but none of them seems to be useful for my purpose: lpSolveAPI is aimed for linear programming only, which is not the case; mco can minimize a multidimensional objective function, but does not seem to be able to manage binary (i.e. decision) variables, needed for combinatorial problems; adagio and CEGO can deal with combinatorial optimization problems, but as far as I can see they can only optimize a single unidimensional function.
Is there any other package I am not aware of that can handle this type of problem? Or any of the aforementioned may be useful, though I may be missing the way to the functionality I need?
Thank you so much in advance with this. It is being really a nightmare trying to find this out.
I was wondering if anyone out there has found a nice package for R to analyse eye-tracking data?
I came across eyetrackR but as far as I can tell there is no English support documentation available:

I will move onto another freeware that handles eye-tracking data if I need to but was really hoping there would be something accessible in R.
Ideas?
Cheers.
It would help if you could explain which kind of analyses you are intending to do. There are many different approaches depending on the research question and the research field. Many approaches involve the detection of fixations and saccades as a first step. An R package that can be used for fixation detection is called saccades and is available on CRAN. See also the Github page of the package for examples and screenshots.
A new eye-tracking analysis package for R (eyetrackingR) was recently released. It provides a variety of methods that handle data preparation/cleaning, visualization, and analysis.
Here's a list of several dozen instances of researcher contributed code (FOSS) for post-acquisition summarization and analysis of eye-movement data. You may be able to find something to suit your needs there.
List is provided in case anyone stumbling across this thread may find it useful.

have been searching around the internet and stackoverflow, but haven't been able to find any information on libraries for machine learning in s-plus or R. does anyone know of any or could perhaps point me in the right direction? thank you!
You should probably start at the CRAN Task View on Machine Learning & Statistical Learning which covers the R side.
this one maybe helpful:machine learning open source software Filter by Programming Language
If your interest in ML on R includes classification and regression algorithms, then you will want to explore CARET. Be advised that, in a recent evaluation, I found the R offerings quite underwhelming when compared to the other ML OSS.
I am searching for a good R package to align multiple spectra.
Thanks.
I don't know exactly what you're looking for, but have you looked at http://bioconductor.org ? The PROcess package seems to have an align method. Also this site here has links to software and source code that may be relevant, even if not in R.
