An isotope natural abundance correction algorithm that
  is needed especially for high resolution mass spectrometers. Supports
  correction for 13C, 2H and 15N. Su X, Lu W and Rabinowitz J (2017)

Estimate group aggregates, where one can set user-defined conditions
   that each group of records must satisfy to be suitable for aggregation. If
   a group of records is not suitable, it is expanded using a collapsing scheme
   defined by the user. A paper on this package was published in the Journal
   of Statistical Software <doi:10.18637/jss.v112.i04>.

Interact with the Attentional Control Data Collection (ACDC).
  Connect to the database via connect_to_db(), set filter arguments via add_argument()
  and query the database via query_db().

The functions are designed to calculate the most widely-used county-level variables in 
  agricultural production or agricultural-climatic and weather analyses. To operate some functions 
  in this package needs download of the bulk PRISM raster. See the examples, testing versions and 
  more details from: <https://github.com/ysd2004/acdcR>.

Provides tools for autoregressive conditional duration (ACD, Engle and Russell, 1998) models. Functions to create trade, price, or volume durations from transaction data, perform diurnal adjustments, fit various ACD models, and test them.

A function for estimating factor models. Give factor-adjusted statistics, 
  factor-adjusted mean estimation (one-sample test) or factor-adjusted mean difference 
  estimation (two-sample test).

The ACE file format is used in genomics to store contigs from sequencing machines.
  This tools converts it into FASTQ format. Both formats contain the 
  sequence characters and their
  corresponding quality information. Unlike the FASTQ file, the ace file stores the
  quality values numerically.
  The conversion algorithm uses the standard Sanger formula. The package facilitates insertion
  into pipelines, and content inspection.

Optimal Bayesian experimental design using the approximate coordinate exchange (ACE) algorithm.
