r_programming_e's Issues

Manual installation can't find some courses

I've done the manual installation using the instructions found here but the lessons

• 10: lapply and sapply
• 11: vapply and tapply
• 12: Looking at Data

can't be started. The error message I get is:

(Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") : cannot open file 'C:/R/R-3.4.0/library/swirl/Courses/R_Programming/lapply_and_sapply/flag.data.txt': No such file or directory

The problem is on the initLesson.R files of these lessons. The files are looking for the data in the R_Programming folder and not in the R_Programming_E folder.

loops

I am very new to R. How do I loop a long number of variables into an equation. For example, the formula for m1 has a variable i. How do I run "fitted.values(m1) for hundreds of values of i? I have watched many videos, but have not found how to do this exact loop. Thanks!

Add LICENSE file to specify open source license

For those wanting to reuse this content, it would be helpful to have a specified LICENSE. Since swirldev has a GPLv3 license, I'm assuming this is the license for this material but it should be specified in the repo.
