extract_non_numerics

nth_non_numeric

first_non_numeric

last_non_numeric

string

Do you want to include the possibility of decimal numbers
(<code>TRUE</code>) or not (<code>FALSE</code>, the default).

decimals

Do you want to allow a leading decimal point to be
the start of a number?

leading_decimals

Do you want to allow negative numbers? Note that double negatives
are not handled here (see the examples).

negs

The index of the number (or non-numeric) that you seek. Negative
indexing is allowed i.e. <code>n = 1</code> (the default) will give you the first
number (or non-numeric) whereas <code>n = -1</code> will give you the last number (or
non-numeric), <code>n = -2</code> will give you the second last number and so on. The
function is vectorized over this argument.

This started out as a package for file and string manipulation.
Since then, the 'fs' and 'strex' packages emerged, offering functionality
previously given by this package (but it's done better in these new ones).
Those packages have hence almost pushed 'filesstrings' into extinction.
However, it still has a small number of unique, handy file manipulation
functions which can be seen in the vignette.
One example is a function to remove spaces from all file names in a
directory.
