Encode in a Common Format

Usage

format(x, ...)
format.default(x, trim=FALSE, digits = .Options$digits)

Arguments

x any R object (conceptually); typically numeric.
trim logical; if TRUE, leading blanks are trimmed off the strings.
digits how many significant digits are to be used for numeric x.

Description

This function converts its first argument to a vector of character strings, which have a common format (as is done by print). The trimming with trim = TRUE is useful when the strings are to be used for plot axis annotation.

The function formatC provides a rather more flexible formatting facility for numbers.

Examples

format(1:10)
for(i in c(1:5,10,15:17,20)) cat(i,":\t",format(pi,digits=i),"\n")
