I would like to create a second data frame that

Hello, I've written a small function that's supposed to save me some time, and it's ending up killing it- the intention is to iteratively subset a dataset fram on framevec, fit a model (either lm or nls depending on type) and return the r2 or AIC from the model, respectively. Although as far as I can tell in my code the plots are dependent on the fit of the model to the data and the

Fake Conferences CSCI and WORLDCOMP of Hamid Arabnia Hamid Arabnia from University of Georgia is well known for his fake WORLDCOMP conferences https://sites.google.com/site/dumpconf This website has an open challenge posted sometime in 2012 and it also has comments from several well-known researchers on WORLDCOMP. Hamd Arabnia never responded to these because his conferences are bogus.

Hi, I have a list of mutations, called "mutList", of the form: > head(mutList) Alu 1 AluJ 2 AluJ/F(R)AM 3 AluJ/FLAM 4 AluJ/FRAM 5 AluJ/monomer 6 AluJb It contains about 500 elements and not all of them contain the sequence "Alu". I tried using this code: Alu<-mutList[which(grep("Alu",mutList)==1)] But that simply returned

I have a command which returns a data fram if I am not mistaken: sc <- split(x, list(x$Category, x$SubCategory), drop=TRUE) Now I wish to get the Category and SubCategory that the data was split on. So my first attempt would be: sc[[1]]$Category[1] But that yields [1] (Unknown) 46 Levels: (Unknown) 10" Plates 7" Plates (Dessert) ... WOMEN Is all I want is '(Unknown)'.

Hi, I have a process using svm from the e1071 library. it works. I want to try using the KSVM library instead. The same data used wiht e1071 gives me an error with KSVM. My data is a data.frame. sample code: svm_formula <- formula(y ~ a + B + C) svm_model <- ksvm(formula, data=train_data, type="C-svc", kernel="rbfdot", C=1) I get the following error:

Hi, What I would like to do is have a data.frame with column names and have these column names stored as strings in another vector.

Esteemed UseRs, This must be embarrassingly trivial to achieve with e.g., melt() and cast(): deduplicating records ("pw.X" in example) for a given set of responses ("cond.Y" in example). Hopefully the runnable example shows clearly what i have and what i'm trying to convert it to. But i'm just not getting it, ?cast that is! So i'd really appreciate some ones
