Cannot see pushed commits on github

Question

I'm working on an assignment on Coursera where we have to fork a repo, clone a local version, make changes and commit then push them.

And I did all of that. But when I check on my repo URL I am unable to see the pushed commit I just made? https://github.com/gcameron89777/ProgrammingAssignment2

I used git config to set my global values for username and email. I went into the actual files of the hidden .git folder in the directory in question and looked at the config file:

url = https://github.com/gcameron89777/ProgrammingAssignment2.git

Now when I visit the URL, I do not see any of my commits. Shouldn't I?

1. I edited the .R file in question and saved it.
2. I then used commit like so: git commit -m "added functions makeCacheMatrix and cacheMatrix"
3. I then pushed using git push

All the while my current directory is the directory in question.

Should I not see the recent commits I just made?

EDIT: Here is the output of git status and git log:

Answer 1

as it comes from git status:

Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git checkout -- <file>..." to discard changes in working directory)
modified:   cachematrix.R

you didn't add your files to the commit - so you basically did commit nothing.

do following:

git add -A
git commit -m "<commit message>"
git push
