[R] Linear regression and stand deviation at the Linux command line

[Keith Christian]

R List,

Please excuse this ultra-newbie post.
I looked at this page but it's a bit beyond me.

I'm interested in R construct(s) to be entered at the command
line that would output slope, y-intercept, and r-squared values read
from a csv or other filename entered at the command line, and the same
for standard deviation calculations, namely the standard deviation,
variance, and z-scores for every data point in the file.

E.g.
$ ((R function for linear regression here))    slope, y-intercept, and
r-squared, other related stats that R seems most capable of
generating.
linear_regression_data.csv file contents (Are line numbers, commas,
etc. needed or no?)
