Homeworks are due at the beginning of class on the due date. Homeworks submitted more than two minutes after class starts will not be graded. Homework submissions must follow the policy detailed below, otherwise they will not be graded. If the TAs are asked to regrade a problem that did not adhere to the guidelines, we will treat the homework as a late submssion.

• Homework must have your eid or full name as listed on Blackboard.
• Homework must be printed or handwritten. The only exceptions are the R scripts that we ask you to submit. We will not print any of the homeworks.
• R scripts must be zipped (.zip) or compressed tar archives (.tar.gz). There should only be 1 compressed file per student (no individual files).
• No nested folders within the student folder.
  
• R code must be submitted in a .R or .r extension. Embedding code in a report or in a text file will not be graded.
• R scripts must be named with the problem they are associated with (e.g. 3.R, 4.R). Our automated script relies on this naming convention to find the right script. Although we prefer one file per problem, students can name the parts separately (e.g. 3a.R, 3b.R).
  
• Any data that was provided on Blackboard will be available in the folder of code execution. We will not manually correct setwd().
• Only submit the R scripts that are necessary, if you submit 2 R scripts for the same problem (e.g. 3.R and 3_final.R), we will randomly decide which R script to execute and your grade will be based on that one.
  

R Code Grading Algorithm

A script will unzip / uncompress all the submissions such that each individual student gets their own folder. Another script will then traverse each student directory, copy the necessary data into the folder (e.g. spam.Rdata), find the appropriate problem files and run the R scripts sequentially. For example, if the folder has the files 3.R, 4.R, 5.R, the R scripts will be run in that order in the same environment.
