Avoiding difficulty

American culture does not take well to the idea of difficulty. Our penchant is for one-step, one-stop solutions to problems, and we expect and demand in all areas of life, including reading, an ease of achievement that is antithetical to thought itself. —Helen Regueiro Elam

Love and loneliness

“I can love you because I want to feel less alone, or I can love you because I want you to feel less alone. But only the latter requires me to imagine a consciousness independent of my own, and equally real.” —Garth Risk Hallberg

Choosing who may judge you

“It was while I was at interview that I finally noticed that subjecting myself to the judgement of an institution which I fundamentally disagreed with was bizarre.” —Elly Nowell, commenting on the rejection letter she sent the University of Oxford

Printing the elements of a vector one per line in R

You know how R prints the elements of a vector horizontally?

> 1:5
[1] 1 2 3 4 5

Today I needed the elements printed one per line. After a bit of searching and hair-pulling, I stumbled upon the cat command:

> cat(1:5,sep="\n")
1
2
3
4
5

This is particularly useful when you need a line-by-line list of the variables in a data frame, which you can get with:

cat(names(dataframe),sep="\n")

To output the list directly to a file, use write instead of cat.
