The infix operator%% is not part of base R, but is in fact defined by the package magrittr and is heavily used by dplyr.It works like a pipe, hence the reference to Magritte's famous painting.What the function does is to pass the left hand side of the operator to the first argument of the right hand side of the operator. In the following example, the data frame iris gets passed to head: library(magrittr)iris%% headSepal.Length Sepal.Width Petal.Length Petal.Width Species1 5.1 3.5 1.4 0.2 setosa2 4.9 3.0 1.4 0.2 setosa3 4.7 3.2 1.3 0.2 setosa4 4.6 3.1 1.5 0.2 setosa5 5.0 3.6 1.4 0.2 setosa6 5.4 3.9 1.7 0.4 setosaThus, iris%% head is equivalent to head(iris).Often,%% is called multiple times to 'chain' functions together, which accomplishes the same result as nesting. For example in the chain below, iris is passed to head, then the result of that is passed to summary.

Iris%% head%% summaryThus iris%% head%% summary is equivalent to summary(head(iris)). Some people prefer chaining to nesting because the functions applied can be read from left to right rather than from inside out.

Letter R from the alphabet by, in (1509)The minuscule (lowercase) form ( r) developed through several variations on the capital form.Along with Latin minuscule writing in general, it developed ultimately from via the script of Late Antiquity into the of the 9th century.In handwriting, it was common not to close the bottom of the loop but continue into the leg, saving an extra pen stroke. The loop-leg stroke shortened into the simple arc used in the Carolingian minuscule and until today.A calligraphic minuscule r, known as (ꝛ), was used in the sequence or, bending the shape of the r to accommodate the bulge of the o (as in oꝛ as opposed to or). Later, the same variant was also used where r followed other lower case letters with a rounded loop towards the right (such as b, h, p) and to write the geminate rr (as ꝛꝛ). Use of r rotunda was mostly tied to typefaces, and the glyph fell out of use along with blackletter fonts in English language contexts mostly by the 18th century.used a minuscule which retained two downward strokes, but which did not close the loop ('Insular r', ꞃ); this variant survives in the popular in Ireland until the mid-20th century (but now mostly limited to decorative purposes).Name The name of the letter in Latin was er ( /ɛr/), following the pattern of other letters representing, such as F, L, M, N and S.

This name is preserved in and many other languages. In, the name of the letter changed from /ɛr/ to /ar/, following a pattern exhibited in many other words such as farm (compare French ferme), and star (compare German Stern).In the letter is called /ɒr/ or /ɔːr/.The letter R is sometimes referred to as the littera canīna (literally 'canine letter', often rendered in english as the dog's letter). This Latin term referred to the Latin R was to sound like a growling dog, a spoken style referred to as vōx canīna ('dog voice'). A good example of a trilled R is in the Spanish word for dog, perro.In 's, such a reference is made by Juliet's nurse in Act 2, scene 4, when she calls the letter R 'the dog's name'. The reference is also found in 's English Grammar. Use in writing systems.
