# How to run a model stored as a .Rda file?

I am using an already written R code which has a line of code as shown below

model_predictors <- buildModel(flag, data, outcomeName, folder)
model<-model_predictors$$model predictorsNames<-model_predictors$$predictorsNames
auc <- model_predictors$$auc save(model, file=paste(folder,studyName,'_model_', flag$$model[1], '_', outcomeName,".Rda",sep=''))


As you can see in the last line of code, the (training) model is saved in folder in a .Rda file format with a naming convention _model_. Now, I have to use this model to test/evaluate on unseen dataset.

So now my question, I see a .Rda file in my folder path and I can load the .Rda file in Rstudio but how do I make inference from this model? I am new to R and can anyone help me with this please?

Can someone help me understand how to run this model please?

model<-tree(Y~X1+X2, data=dataset) #estimate of the tree model
