Hi Sorry if this is too silly to ask. I did RTFM and didn''t find anything obvious. I have a helper class for my controller which needs to singularize words. I need to access methods in the ActiveSupport/CoreExtensions/String/Inflections class. Doing a require ''ActiveSupport/CoreExtensions/String/Inflections'' fails. How do I add this specific class to a helper class

Hi R-helpers , can you please let me know the methods in which NULL values can be handled in R? Are there any generic commands/functions that can be given in a workspace,so that the NULL values occuring in that workspace (for any datasets that are loaded , any output that is calculated) , are considered in the same way? Thanks in advance. -- View this message in context:

Hi R-helpers , am trying out nnet package in R. Does nnet package work only for numerical values as inputs? Can somebody give an insight on how categorical values as inputs are handled using nnet in r with an example? Thanks in advance for your help. -- View this message in context: http://r.789695.n4.nabble.com/non-numerical-values-as-input-using-nnet-tp2991623p2991623.html Sent from the R help

Hi All, We have an application which uses R algorithms. We are currently using save() command to store models.But for save() command, we have to give the filename.But, in our application, we cannot afford to save it in any specific location. In this case , for accessing the models generated in R , we cannot use the save() command since, save () stores the pmml in local file. Is there any way

Hi R-Helpers , am working on nnet package.Multinom() has an option for finding the goodness of fit by giving the AIC value. Does nnet also gives some value to determine the accuracy. If not, can you guide me with some procedure to figure out the accuracy/goodness of fit of nnet model? Thanks in advance. -- View this message in context:

Hi R-helpers, I am using rpart package for decision tree using R.We are invoking R environment through JRI from our java application.Hence, the result of R command is returned in REXP and we use geterrMessage() to retrieve the error.

Hi All, I was using the following command for performing kmeans for Iris dataset. Kmeans_model<-kmeans(dataFrame[,c(1,2,3,4)],centers=3) This was giving proper results for me. But, in my application we generate the R commands dynamically and there was a requirement that the column names will be sent instead of column indices to the R commands.Hence, to incorporate this, i tried using the R
