A particle may be distinguished by multiple subscripts, such asībb for the triple bottom omega particle. Thus electron, muon, and tau neutrinos are denoted One of the most famous molecules, water, is known almost universally by its chemical formula: H 2O (meaning that it contains 2 hydrogen atoms and 1 oxygen atom.)Ī subscript is also used to distinguish between different versions of a subatomic particle. For example, the chemical formula for glucose is C 6 H 12 O 6 (meaning that it is a molecule with 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms). Perhaps the most familiar example of subscripts is in chemical formulas. Subscripts that are dropped below the baseline Most fonts that contain superscript/subscript will have predetermined size and orientation that is dependent on the design of the font. Despite these differences, all reduced-size glyphs go by the same generic terms subscript and superscript, which are synonymous with the terms inferior letter (or number) and superior letter (or number), respectively. For example, subscript letters on the baseline are quite rare, and many typefaces provide only a limited number of superscripted letters. Because each position is used in different contexts, not all alphanumerics may be available in all positions. The four most common positions are listed here. The typeface is Myriad Pro.Ī single typeface may contain sub- and superscript glyphs at different positions for different uses. The four common locations of subscripts and superscripts. Superior and inferior figures on the baseline are used for fractions and most other purposes, while lowered inferior figures are needed for chemical and mathematical subscripts. In English, most nontechnical use of superiors is archaic. In typesetting, such types are traditionally called "superior" and "inferior" letters, figures, etc., or just "superiors" and "inferiors". The vertical distance that sub- or superscripted text is moved from the original baseline varies by typeface and by use. medium or bold typography) than a reduced-size character would be. In professional typography, subscript and superscript characters are not simply ordinary characters reduced in size to keep them visually consistent with the rest of the font, typeface designers make them slightly heavier (i.e. Subscripts and superscripts are perhaps most often used in formulas, mathematical expressions, and specifications of chemical compounds and isotopes, but have many other uses as well. Subscripts appear at or below the baseline, while superscripts are above. It is usually smaller than the rest of the text. The second typeface is Myriad Pro the superscript is about 60% of the original characters, raised by about 44% above the baseline.)Ī subscript or superscript is a character (such as a number or letter) that is set slightly below or above the normal line of type, respectively. (The top typeface is Adobe Garamond Pro the size of the subscript is about 62% of the original characters, dropped below the baseline by about 16%. The visual weight of the first "2" matches the other characters better. In each example the first "2" is professionally designed, and is included as part of the glyph set the second "2" is a manual approximation using a small version of the standard "2". R^2? You can also see that there is a slight shift in the alignment of RMSE with respect to R.Example of subscript and superscript. How can I add the unit for RMSE after the value and superscript 2 after R i.e. Hjust = -0.1, vjust = vertical_adjustment, size=3.5) P + geom_text(data = df.annotations, aes(x=-Inf, y=+Inf, label=label), Vertical_adjustment = ifelse(grepl("R",df.annotations$label), 1.5, 3) # This here is important, especially naming the first columnĬolnames(df.annotations) <- c("Species", "label") # Here we create our annotations data frame. Theme( = element_blank(), = element_blank()) Geom_smooth(method=lm, fill="black", formula = y ~ x) + P <- ggplot(data=iris, aes(x = Sepal.Length, y = Petal.Length)) + RMSE = RMSE(Sepal.Length, Petal.Length)) %>% Summarise(R = cor(Sepal.Length, Petal.Length, use=""), I am using the following code library(caret) I am trying to use superscript in geom_text.
