I'm searching for a package or a way to use the algorithm Adaboost.R2 (adaboost for regression) in R. I can use it in ROOT and change my loss function in "quadratic" and I want to get the same thing in R. Someone can help me? Thanks.

I used Caret to create a regression model of a dataset in R, and I wish to find this equation for usage in other websites (e.g. Desmos). I am unable to find info anywhere on how to do this, so if anyone has answers, that would be much appreciated! :D
I'm really confused about regression models and functions in R. Here is my problem. I'm using the PLS package to make a model like Y~x. To do that I have to use 'plsr':
model=plsr(Y~X,ncomp=10,data=df1,center=TRUE, scale=TRUE, validation="LOO")
I couldn't find the source of the 'plsr' in the PLS source code but in the help document it says it refers to 'mvr{pls}' which I could find it. first is 'plsr' a function or model.. in the R terminology? is it built in R? and how does it refer to 'mvr' function in pls package?
Thanks
I would like kindly to ask if anybody has an idea how to build a genetic algorithm GA model that is able to solve the "diet problem" with constraints and minimization objective in R?
thank you and appreciate your contribution
I use rgenoud package in R. See paper here: http://sekhon.berkeley.edu/papers/rgenoudJSS.pdf
I am working on clustering of variables in matlab. Two functions come in ClustOfVar package in R, called hcluster() and cutreevar().
I am good in Matlab and would like to use alternatives of hcluster() and cutreevar() in it.
Does Matlab has any inbuilt function which computes exactly same as hcluster() and cutreevar() does in R?
Need help.
Thanks
for heirarchical clustering you'll probably want to look at clusterdata. Note that you'll need the statistical toolbox for this function.
I am actually trying to perform a Generalized SCHUR decomposition in R. It looks like the package MATRIX only do the usuall SCHUR decomposition. I would like to know if there is any other package that does it. I read in some blog that we can actually call lapack function(DGGES.f) in R. I don't know how to do since DGGES depends on another external subroutine (SELCTG) to be defined by the user.
Your help will much appreciate.
Thanks in advance
