R world provides several packages for working with network
data.  This package supplements that functionality by providing
methods for converting network data objects between classes
defined in other packages. Currently supported classes:
network, igraph0. This version is compatible with legacy
version of igraph (prior to 0.6, renamed to igraph0).  Future
versions of 'intergraph' will be compatible with new igraph API
(0.6 or later).

Coercion Routines for Network Data Objects
Functions implemented in this package allow to coerce (i.e.
convert) network data between classes provided by other R packages.
Currently supported classes are those defined in packages: network and
igraph.

Scheduling Interim Analyses in Clinical Trials
Allows the simulation of both the recruitment and treatment phase of a clinical trial. Based on these simulations, the timing of interim analyses can be assessed.

App for Scheduling Interim Analyses in Clinical Trials
Allows an interactive assessment of the timing of interim analyses. The algorithm simulates both the recruitment and treatment/event phase of a clinical trial based on the package 'interim'.

Converts matrices and lists of matrices into a single vector by interleaving
their values. That is, each element of the result vector is filled from the input
matrices one row at a time. This is the same as transposing a matrix, then removing the
dimension attribute, but is designed to operate on matrices in nested list structures.
