[R] Help with Programmin-1 submission.

[John McKown]

Gary,

First off, I doubt anyone here will really be able to help you with a
question which is, basically, "How do I submit the R code that I've
worked on to my college as an answer to a programming assignment".
Unless by chance someone else here happens to be taking that course
and knows how to. It's not really an R programming question.

What I can help you with is an apparent misunderstand by you of what
source() does. source() is simply a way to say: read the lines in the
named "file" (not always a disk file) and act as if I had typed it all
in myself on the R command prompt.

Well, I may be chided a bit by others. But I'm bored this morning. And
I don't feel that this is actually a "homework problem". So I looked
at the R code at
http://d396qusza40orc.cloudfront.net/rprog/scripts/submitscript1.R and
at your transcript. Try the following commands:

source("http://d396qusza40orc.cloudfront.net/rprog/scripts/submitscript1.R")

setwd('H:/RStudio-Projects/Project1/')

submit()

Note that I replaced the second source() with a setwd() command. The
first source() defines some R programs for you. The setwd() makes your
"current working directory" be H:/RStudio-Projects/Project1/ which I
guess is where pollutantmean.R resides. The submit() function looks
for a __FILE__ in the __current working directory__ for the code which
you want to submit to your instructor. From what I can see, the
submit() process itself does the required source() to run your R code,
but only from your __current working directory__ (yes, I'm emphasizing
that). The rest of what you did after the submit() command looks to
match what the submit() function was wanting.

Now, I will emphasize yet again that this question is totally outside
the purview of this forum. Your question should have been asked of
your teacher, or a TA, or (as we were called back when I was in
college) a "user's ass" (we weren't P.C,. or even polite, back in the
60s. I had to help people with key punch machines and card readers). I
only went into this because: (1) I'm bored and (2) you look like you
might be just a bit younger that me and I believe in helping kids
succeed <grin>.
