"The following table gives the default math keywords, their target characters and codes along with spacing and linear-format build-up properties."
Omitted from the original table are operands, enclosures, spaces, big/long variants, and non-NFKC characters. Three characters that default to their emoji variants on iOS, and one related character, are excised.

The design, re-design, and implementation of [SE-0104], a proposal to revise integer protocols in Swift, is now largely complete in shipping previews of Swift 4. As an exercise, I have used the new APIs to develop a [set of additional numeric facilities]. Here are some insights gained from that experience--and from two unpublished exercises to implement a BigInt type (one from scratch, one wrapping GMP)--as well as suggestions for improvement.
protocol Arithmetic : Equatable, ExpressibleByIntegerLiteral
An type that provides certain arithmetic operations (addition, subtraction, and multiplication).
Types that conform to
Arithmetic satisfy the following conditions for any values
(unless the result of an operation overflows the maximum size of the conforming type):
+) is commutative; that is,
a + b == b + a
We propose to complete Swift's suite of range operators to introduce a fully open range (
<.<) and the second complementary half-open range (
|my.data.frame <- read.delim("tab_delimited_file_with_probeset_ids_in_first_column.txt", row.names=1)|
|my.data.matrix <- as.matrix(my.data.frame)|
|# PCA by sample:|
|# center each gene (mean) without scaling|
|# scale each sample (root mean square) without centering|
|# transpose the matrix to PCA by sample instead of by gene|
|a <- scale(t(my.data.matrix), center=TRUE, scale=FALSE)|
|b <- scale(t(a), center=FALSE, scale=TRUE)|
