Sometimes when an information frame is read directly from a file, a column youâ€™d thought would produce a numeric vector as a substitute produces a factor. This is brought on by a non-numeric value within the column, usually a missing worth encoded in a particular means like . To remedy the state of affairs, coerce the vector from an element to a character vector, after which from a personality to a double vector. Dimensions, used to show vectors into matrices and arrays, described in matrices and arrays.
