In ChristianAmes/FastRet: Retention time prediction and subset selection with a GUI

Model upload

Here you need to upload a prediction model generated with this programm in the "Train new Model" mode. This Model can also be read in with R by calling

model<- readRDS( path to model file )

Things you can do with this are e.g. analyzing lasso coefficients for a model:

coef(codel$final_model)

or analyzing the predictor set with

model$predictor_set

In detail this R object contains the following information:

• which method was used
• the final model, either a glmnet or xgboost object depending on the method
• scaling model, simple prediction model to scale and center new data
• predictor set, consisting of the whole sample/varaible matrix used for training the model
• statistical measures for all cross validation steps
• which split was used for the cross validation
