Error, using package caret

[njimenez]

God day ,

I am using package caret , but at moment of executing my code show the word "selection:" in the console . Can anyone help me what is wrong ( I'm new in this program )?

The code is :

**tiempoI <- Sys.time()**
**pf_model <- caret::train(pf_Xtrain, pf_Ytrain_Lbl, method="C5.0",  **
**                         qtuneGrid = c50Grid, varbose = TRUE,**
**                         metric = "ROC", trControl = control)**
**tiempoF <- Sys.time()**

The result in the console is :

**> tiempoI <- Sys.time()**
**> pf_model <- caret::train(pf_Xtrain, pf_Ytrain_Lbl, method="C5.0",  **
**+                          qtuneGrid = c50Grid, varbose = TRUE,**
**+                          metric = "ROC", trControl = control)**
**Selection: tiempoF <- Sys.time()**
**Selection:** 

Thanks a lot

I suspect that it wants you to install a required package. There is a prompt to do that. What version of the package are you using?
