usefun: A Collection of Useful Functions by John
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 like 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,
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 Markdown document.
Also included is a function that returns the statistics needed for plotting a ROC curve.
