Change selected element names.

1	colname(x) <- value

`x`	an object with named elements
`value`	named character vector

Changing column names is a common task. One can change them all at once, e.g.

colnames(x) <- c(...)

names(x) <- c(...)

or one at a time, e.g.

names(x)[names(x)==old] <- new

reshape supplies rename, a function that changes a subset of identified names, returning the object itself.

library(reshape)

x <- rename(x, c(label=value,...))

In contrast, name and its data frame equivalent colname change a subset of identified names using assignment syntax.

name(x) <- c(label=value,...)

used for side effects

In some cases the column name being replaced must be quoted for the replacement to work. For example, when running colname to replace a column name that contains a special character like '_' or '*', it is necessary to place quotes around the column name.
