hadron
is an R
package, which is now available on CRAN.
hadron
represents a toolkit to perform statistical analyses of correlation
functions generated from Lattice Monte Carlo simulations. In
particular, a class cf
for correlation functions and
methods to analyse those are defined. This includes (blocked)
bootstrap (based on the boot
package) and jackknife, but also an
automatic determination of integrated autocorrelation
times. hadron
also provides a very general function
bootstrap.nlsfit()
to bootstrap a non-linear least squares fit.
More specific functions are provided to extract hadronic quantities
from Lattice Quantum Chromodynamics simulations, a particular Monte
Carlo simulation,(see e.g. European Twisted Mass Collaboration, P. Boucaud et
al. (2008) doi:10.1016/j.cpc.2008.06.013). Here, to determine
energy eigenvalues of hadronic states, specific fitting routines
and in particular the generalised eigenvalue method (see
e.g. B. Blossier et al. (2009) doi:10.1088/1126-6708/2009/04/094
and M. Fischer et al. (2020)

In addition, input/output and plotting routines are available.
