Improvements for R Fundamentals Part2.Rmd

[msamfair]

Thanks for the R-Fun update, I thought it flowed really well! When I was helping Marina with Part 2 yesterday, we just noticed a couple of things:

The working directory of the R Project file is somehow set to R-Fundamentals-main/lessons, rather than R-Fundamentals-main. Resetting the working directory inside a code chunk does not change it throughout the notebook, which caused some confusion.

Also, on line 400, there are 2 commands on the same line that should be on two lines:
"sleep_select <- select(sleep_VIM, BodyWgt, BrainWgt) dim(sleep_select)"

Last thing is just a question - on line 414 where the pipe operator is introduced, there is a \ in "%>%". Is that intentional so that the pipe symbol renders correctly once knitted?

Thanks and let me know if I can clarify anything!

I cannot replicate the R project working directory file problem. One possibility is that individuals are opening the .Rmd file before opening the Rproject file.

Is this what happened?

Oh good point, that is the source of the error. I'll mention that to Marina as well so we both know for next time, thanks Alex!
