Coordinate names for relativity

Description

Trivial function to set coordinate names to “t”, “x”, “y”, “z”.

Usage

coordnames(...)
flob(x)

Arguments

...	Further arguments, currently ignored
x	A matrix

Details

Function coordnames() simply returns the character string c("t","x","y","z"). It may be overwritten. Function flob() sets the row and columnnames of a 4\times 4 matrix to coordnames().

Note

If anyone can think of a better name than flob() let me know.

coordnames()

flob(diag(3))
flob(matrix(1,4,4))

## You can change the names if you wish:
coordnames <- function(x){letters[1:4]}
flob(outer(1:4,1:4))
