r

I want to extract the first (or last) n characters of a string. This would be the equivalent to Excel''s LEFT() and RIGHT().

newline

I have used r in my own console apps where I am testing out some code and I don''t want to see text scrolling up my screen, so rather than use n after printing out some text, of say, a frame rate (FPS), I will printf("%-10dr", fps); This will return the cursor to the beginning of the line without moving down to the next line and allow me to

R (programming language)

R is a programming language for statistical computing and data visualization has been adopted in the fields of data mining, bioinformatics and data analysis. [9]The core R language is augmented by a large number of extension packages, containing reusable code, documentation, and sample data.. R software is open-source and free software is licensed by the GNU

Difference between modes a, a+, w, w+, and r+ in built-in open

The modes r, w, x, a are combined with the mode modifiers b or t. + is optionally added, U should be avoided. As I found out the hard way, it is a good idea to always specify t when opening a file in text mode since r is an alias for rt in the standard open() function but an alias for rb in the open() functions of all compression modules (when e.g. reading a *.bz2 file).

How to join (merge) data frames (inner, outer, left, right)

By using the merge function and its optional parameters:. Inner join: merge(df1, df2) will work for these examples because R automatically joins the frames by common variable names, but you would most likely want to specify merge(df1, df2, by = "CustomerId") to make sure that you were matching on only the fields you desired.

syntax

Update 2 R has defined a |> pipe. Unlike magrittr''s %>% it can only substitute into the first argument of the right hand side. Although limited, it works via syntax transformation so it has no performance impact. As of R v4.1.0, |>, is included in base-R and being advocated by the Tidyverse in place of %>% for most use cases. See R for Data

normalization

I have to assume you meant to say that you wanted a mean of 0 and a standard deviation of 1. If your data is in a dataframe and all the columns are numeric you can simply call the scale function on the data to do what you want.

r

@Konrad Rudolph R uses some rules/principles when designing the language and code interpretation for efficiency and usability that not saw in other languages. I believe most people who ask the difference between = and <- is curious about why R has more than one assignment operator compared with other popular Science/math language such as Python.

What is the difference between r and n?

More importantly, Unix tends to use n as a line separator; Windows tends to use rn as a line separator and Macs (up to OS 9) used to use r as the line separator. (Mac OS X is Unix-y, so uses n instead; there may be some compatibility situations where r is used instead though.) For more information, see the Wikipedia newline article.
