Working​ ​on​ ​R​ ​Markdown​ ​File​ ​in​ ​the​ ​Labs


First,​ ​you​ ​need​ ​to​ ​download​ ​the​ ​instructional​ ​markdown​ ​files​ ​from​ ​the​ ​Lab
Instructions​ ​page.​ ​If​ ​Chrome​ ​doesn’t​ ​work,​ ​please​ ​switch​ ​to​ ​another​ ​browser​ ​to
download.​ ​Or​ ​you​ ​could​ ​change​ ​the​ ​file’s​ ​.txt​ ​extension​ ​to​ ​.Rmd​ ​downloaded​ ​from
Chrome.

Next,​ ​open​ ​the​ ​.Rmd​ ​file​ ​that​ ​you​ ​just​ ​downloaded​ ​with​ ​RStudio.​ ​The​ ​file​ ​contains
detailed​ ​instructions​ ​on​ ​how​ ​to​ ​do​ ​the​ ​lab​ ​and​ ​all​ ​lab​ ​questions.​ ​At​ ​this​ ​point,​ ​you
should​ ​be​ ​familiar​ ​with​ ​basic​ ​.Rmd​ ​file​ ​structures.​ ​Type​ ​in​ ​your​ ​own​ ​codes​ ​to​ ​answer
the​ ​questions​ ​between​ ​‘’’​ ​ ​‘’’​ ​where​ ​there​ ​is​ ​a​ ​“#​ ​type​ ​your​ ​code​ ​for​ ​Question​ ​X​ ​here,
and​ ​Knit”.​ ​The​ ​code​ ​chunks​ ​usually​ ​occur​ ​after​ ​each​ ​question.

If​ ​the​ ​code​ ​chunks​ ​are​ ​not​ ​light​ ​grey,​ ​that​ ​almost​ ​certianly​ ​means​ ​you​ ​still​ ​have​ ​a​ ​txt
document​ ​and​ ​you​ ​should​ ​use​ ​File-​ ​Save​ ​As​ ​and​ ​save​ ​the​ ​file​ ​with​ ​a​ ​short​ ​file​ ​name
and​ ​the​ ​suffix​ ​Rmd,​ ​like​ ​lab1.Rmd
Next,​ ​after​ ​typing​ ​in​ ​all​ ​codes​ ​for​ ​all​ ​the​ ​questions​ ​in​ ​the​ ​.Rmd​ ​file,​ ​you​ ​could​ ​go
ahead​ ​and​ ​knit​ ​the​ ​file​ ​to​ ​an​ ​.html​ ​file.​ ​To​ ​do​ ​that,​ ​click​ ​“Knit”​ ​(or​ ​for​ ​some​ ​people,
the​ ​button​ ​is​ ​called​ ​(Racheal,​ ​what​ ​is​ ​the​ ​button​ ​called​ ​in​ ​your​ ​RStudio?)).​ ​An​ ​.html
file​ ​will​ ​be​ ​produced​ ​with​ ​your​ ​codes​ ​and​ ​results.

Finally,​ ​don’t​ ​forget​ ​to​ ​fill​ ​in​ ​the​ ​answers​ ​to​ ​these​ ​lab​ ​questions​ ​in​ ​the​ ​lab​ ​quiz​ ​to​ ​get​ ​a
score.
