Thanks you very much.
The issue resolved by just upgrading the R and R studio to their latest versions. All the packages are now successfully installed. Henceforth, the code runs absolutely okay. -- Muhammad Bilal Research Fellow and Doctoral Researcher, Bristol Enterprise, Research, and Innovation Centre (BERIC), University of the West of England (UWE), Frenchay Campus, Bristol, BS16 1QY muhammad2.bi...@live.uwe.ac.uk<mailto:olugbenga2.akin...@live.uwe.ac.uk> ________________________________ From: ruipbarra...@sapo.pt <ruipbarra...@sapo.pt> Sent: 08 May 2016 11:57:22 To: Muhammad Bilal Cc: Jeff Newmiller; r-help@r-project.org Subject: Re: [R] trainControl and train functions are not found in caret package Hello, Works with me, but I'm using R v 3.3.0.
