remove_commented_and_empty_lines

a character vector, usually the result from using the
<code><a rd-options="" href="/link/readLines?package=usefun&version=0.4.1" data-mini-rdoc="usefun::readLines">readLines</a></code> function

lines

Removes empty or commented lines from a character vector (each element being
a line)

A set of general functions that I have used in various
projects and in other R packages. They support some miscellaneous operations
on data frames, matrices and vectors: adding a row on a ternary (3-value)
data.frame based on positive and negative vector-indicators, rearranging a
list of data.frames by rownames, pruning rows or columns of a data.frame
that contain only one specific value given by the user, checking for matrix equality,
pruning and reordering a vector according to the common elements between its
names and elements of another given vector, finding the non-common elements
between two vectors (outer-section),
normalization of a vector, matrix or data.frame's numeric values in a specified range,
pretty printing of vector names and values in an R notebook (common names and
values between two vectors also supported), retrieving the parent directory of
any string path, checking whether a numeric value is inside a given interval,
trim the decimal points of a given numeric value, quick saving of data to a file,
making a multiple densities plot and a color bar plot and executing a plot
string expression while generating the result to the specified file format.
