is.rownames returns whether elements of a character vector are rownames of an object.
is.rownames(nm, x)
nm |
character vector. |
x |
object whose rownames are desired to be tested. |
If the object does not have any rownames, then the function will return 'FALSE' for each element of the character vector.
TRUE for every element of 'nm' that is a rowname of x and FALSE otherwise. The structure is a logical vector with length = length('nm') and names = 'nm'. See details for special cases.
