ls
bin COPYING etc include lib library modules NEWS NEWS.pdf SVN-REVISION
- /usr/include/R
ls
Rconfig.h Rembedded.h R.h Rinternals.h Rversion.h
Rdefines.h R_ext Rinterface.h Rmath.h S.h

Now, where can I find more RAM for my foggy brain?!

Display Full Directory Location in Nautilus
Well, as usual, there is a round-about way.
Type:
Alt+F2
Run:
dconf-editor
In the dconf-editor menu:
Location Bar options are stored under
"org ➜ gnome ➜ nautilus ➜ preferences ➜ CHECK always-use-location-entry"
Whew. I am glad I can see precisely where I am and copy and paste locations into the terminal once more instead of staring clueless at the vague "pretty' buttons. I remember that when Gnome was in version 2.x, they had the option to change the location display format right under the preferences section of Nautilus.
It's somewhat cruel to take away the means to easily change display format options from an application like Nautilus and hide all of it under system configurations ONLY accessible by installing the dconf-editor.
Ugh. What were the Gnome 3 developers thinking??

On the handmade path
This brilliant brittle white mushroom bunch looked like it had to be saturated with some calcium salt. (e:matthew) and I wondered about the source.
Contrast that with this one - possibly filled with iron salts or rust.
It was such a happy day! Behold the cutest smile on the planet! :)
(e:Paul) taking the panoramic shots...
These great rotting branches reminded me of my muscle dissection days.
We plodded through a rustic-looking huge open field of fluffly little dandelion-like plants. We had fake "snowball" fights and all the little fluffy things ended up attacking me. I think (e:YesThatCasey) totally incited the attack.
I (not so secretly) spied on (e:matthew)-magic. :)

It's NOT rihanna.
I can't stand her awfully nasal bland emotionless voice. To me, she sounds like nails on chalkboard. And also very suspiciously like she is from Rochester.
Scratch that. Nails on chalkboard is actually bearable. But the second resemblance kind of ruins it for me.
It's bat for lashes in one of her quirky moods.

Programming basics from Paul
Who knows.
I believe it's not too late though. So I am going to learn, regardless of how long it takes to get to minimum proficiency.
Some basics that I sponged up
A variable: something that varies. It can be many types.
- Float (yeah, not the cruise one but just as fun: a number).
- Integer, a natural number (and organic to boot).
- String, a word which may or may not mean just that.
- Boolean, true or false and nothing else in between.
- Arrays, a collection of random stuff. (Also called lists in the R world).
- Objects: this has a sort of equivalent in R. When I define a logistic regression model in R, I am trying to describe how an outcome variable (say, any cancer yes/no) is related to many other variables (say, family history, alcohol consumption, body mass index etc.) Since it's a logistic regression, it has some properties or assumptions. The method of combination of my other variables is linear (there are no second or higher order terms in the equation). There are many options that you can put into this "model". How would the model accept other variables? How many variables can it accept before it becomes illogical or the power to say anything conclusively runs out? etc. Once this object or model is defined, you can change some variable in it, and see how the model changes - for example is a non-alcoholic as likely to respond as well to cancer chemotherapy as an alcoholic? If I run this model in R, I will get several properties of this model - that define how this model is behaving. So the model along with its defined and computed properties is a sort of "object": an artificial emulation of a slice of reality (or fantasy).
Indexing: helps in selecting and choosing particular variables that you have defined above Though we didn't talk about it yesterday, indexing in one key weapon in R that gets you out of many scrapes. In its most simple form, it is array[x], or data.frame[x], or list[x] where x is some number. x can be defined and derived in a million different ways. A tip of the hat to Tim Toady!

The land of might have been
So many lands of might have beens. It's hard to keep count at this point. Every one of them strewn with some level of regret.

Oh demon, Alcohol!
I am appointing (some excellent song-writing by The Kinks) this song as THE anthem in my warpath.
And of course, I am writing my own lyrics. Come on now, whoever dares will sing the refrain with me (and try and stick to the tune!).
..
Oh demon, alcohol
Sad memories I CAN recall
You know what I am going to say
Slay the demon alcohol!
Beer, wine, pink gin,
You may NOT drink anything
Port, pernod or tequila,
Rum, scotch, vodka on the rocks,
I hate them ALL.
And this is MY blog and I reserve the right to heap insults and pull down whatever noxious influence that I deem worthy of my undying hatred. I don't think my complete disenchantment with this evil addictive substance that is wrecking live(r)s around me needs any moderation. I also don't need any balancing comments because you KNOW in your hearts that you are plain wrong if you are defending the demon alcohol. Just know that this is one issue that I am most irrevocably proud to hold a complete, clear and blanket one-sided view on.
