In tablesgg: Presentation-Quality Tables, Displayed Using 'ggplot2'

Description Usage Arguments Details Value

Identify strings in a character vector that cannot be interpreted as valid numbers. This is an internal utility function, not intended to be called by package users.

1	notANumber(x, result=c("logical", "values"))

`x`	A character vector.
`result`	The form of result to be returned (see VALUE).

Which character strings can or cannot be interpreted as valid numbers is determined by the function as.numeric. Note that the empty string "" is considered a valid representation of NA.

If result is "logical", a logical vector as long as x that is TRUE for those elements that cannot be interpreted as valid numbers. If result is "values", a character vector containing the unique values in x that cannot be interpreted as valid numbers.
