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

[Sorkin, John]

Keith,
I suggest you being by looking at a web page

https://www.rdocumentation.org/packages/stats/versions/3.6.2/topics/lm

It will introduce you to the lm function, the function that performs liner regression and the summary function which returns some of the material you are looking for. The page come complete with code that can be run via he web page. Once you review the web page, and hopefully try to run the analysis you want to run, you can again ask the R help list for additional help.

There are other web pages that can help you, for example

https://www.statology.org/logistic-regression-in-r/#:~:text=How%20to%20Perform%20Logistic%20Regression%20in%20R%20%28Step-by-Step%29,Predictions%20...%205%20Step%205%3A%20Model%20Diagnostics%20

Take the first steps, show that you are trying and the R help list will be very helpful.

R List,

Please excuse this ultra-newbie post.
I looked at this page but it's a bit beyond me.
https://www2.kenyon.edu/Depts/Math/hartlaub/Math305%20Fall2011/R.htm

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?)
1 20279
2 899
3 24747
4 12564

$ ((R function for standard deviation here))    standard deviation,
variance, z-scores, other related stats that R seems most capable of
generating.
standard_deviation_data.csv file contents (Are line numbers, commas,

Many thanks,
