is.row.names {str2str}

Test for 'row.names'

Description

is.row.names returns whether elements of a character vector are row.names of an object.

Usage

is.row.names(nm, x)

Arguments

nm

character vector.

x

object whose row.names are desired to be tested.

Details

If the object does not have any row.names, then the function will return 'FALSE' for each element of the character vector. As a reminder, row.names does not respond to a manually added "row.names" attribute (e.g., to a vector). If this is tried, then is.row.names will return 'FALSE' for each element 'nm'.

Value

TRUE for every element of 'nm' that is a row.name of x and FALSE otherwise. The structure is a logical vector with length = length('nm') and names = 'nm'. See details for special cases.

Examples

data("mtcars")
is.row.names(x = mtcars, nm = c("Mazda RX4","mazda RX4"))
