Inspect character and factor vector — inspect

Checks character or factor vector to determine whether it might be best to convert to numeric.

Usage

inspect_type(x, xname = NULL, verbosity = 1L, thresh = 0.5, na.omit = TRUE)

Arguments

x: Character or factor vector.
xname: Character: Name of input vector x.
verbosity: Integer: Verbosity level.
thresh: Numeric: Threshold for determining whether to convert to numeric.
na.omit: Logical: If TRUE, remove NA values before checking.

Value

Character.

Details

All data can be represented as a character string. A numeric variable may be read as a character variable if there are non-numeric characters in the data. It is important to be able to automatically detect such variables and convert them, which would mean introducing NA values.
