Make syntactically valid names

For atomic vectors, these functions will sanitize the values. Otherwise, they will set names(), rownames(), and/or colnames() without modification of the values.

Usage

makeNames(object, ...)

# S4 method for character
makeNames(object, unique = TRUE, smart = FALSE)

# S4 method for factor
makeNames(object, unique = TRUE, smart = FALSE)

Arguments

object

Object.

unique

logical(1). If TRUE, the resulting elements are unique. Recommended by default, for syntactically valid names (e.g. column, row names). Note that this is disabled by default for make.names().

smart

logical(1). Handle complicated special cases, such as mixed case acronyms, plus/minus, percentages, etc.

...

Additional arguments.

Value

Modified object.

Details

Sanitizes names using underscores instead of dots, the convention used by make.names().
