cts 1.0-24 (2026-03-17)

• Modernize Fortran sources for current compilers (e.g., gfortran/flang): replace old-style CHARACTER*n declarations with CHARACTER(LEN=n) and remove nonconforming tab characters to reduce -pedantic warnings. convert labeled DO/CONTINUE loops to block DO/END DO in several routines, improving readability and maintaining compatibility with modern Fortran compilers.
• Documentation maintenance: add missing \\value sections for exported functions and update Rd usage/ arguments to match code changes.
• Vignette maintenance: ship a pre-rendered static vignette output (HTML) to avoid long-running or fragile vignette rebuilds during R CMD check.
• DESCRIPTION / metadata: expand Description text and update maintainer/citation information.

cts 1.0-21 (2017-04-28)

• change package= to PACKAGE= when calling .Fortran in R function
• to register native routines and to disable symbol search

cts 1.0-19 (2014-02-27)

• added pre2 and prv2 in car object for fitted values with variances

cts 1.0-18 (2013-08-22)

• modified to remove calls to plot.spec for R version 3.1.0
• add inst/COPYRIGHTS

cts 1.0-17 (2013-06-21)

• delete LAPACK source files dgetrs.f and dgetrf.f, instead call these subroutines in LAPACK
• update author field in DESCRIPTION

cts 1.0-16 (2013-06-13)

• The estimates of all the other variances (in this case the forecast value variance) must by multiplied by this residual variance.
• Lazy Fortran programmers often specify Fortran dimensions as 1 rather than * or a real bound: d1rply.f, d2rply.f, d3rply.f, d4rply.f, d5rply.f, d6rply.f, d7rply.f, d8rply.f, d9rply.f

cts 1.0-12 (2012-07-25)

• changed the Fortran subroutine cspec to the calculation of the spectrum
• added a new parameter frmult in function spectrum which can be used to muliply the frequency range
• added AIC and BIC values in the output of function car

cts 1.0-11

• changed the limit of number of observations from 500 to 5000

cts 1.0-10 (2012-04-05)

• in R function car, to avoid array overrun, change the following lines phi <- .Fortran("setupdate", phi1=double(order), to phi <- .Fortran("setupdate", phi1=double(20),

cts 1.0-9 (2012-01-15)

• modify plot.spec.ls
• change R function names plot.spec.car and plot.spec.ls.

cts 1.0-8 (2011-11-22)

• The package failed test/build on Mac machines with version 1.0-6 and 1.0.7. Removed machine.f and used the envirn.f in version 1.0-5, and add getmin.f and store.f in version 1.0-5.

cts 1.0-7 (2011-11-18)

• modify car.R to generate machine.txt with an extra end line as a workaround for Fortran machine.f failure on Mac machines

cts 1.0-6 (2011-11-15)

• add Fortran source file diagram
• add Fortran source file machine.f to read the machine dependent information written by R function car_control
• replace sgefa.f with dgetrf.f, and sgesl.f with dgetrs.f in lycsr.f and mepad.f (sgefa.f and sgesl.f are indeed dgefa.f and dgesl.f, respectively, in Netlib).
• remove unused Fortran source file sgesa.f, sgesl.f, dpodi.f, envron.f

cts 1.0-5 (2011-08-28)

• replace two values computed by calling envron in envirn.f, and remove envron.f. The machine dependent paramaters in envirn.f caused a failure of test/build on Windows machines.

cts 1.0-4 (2011-07-23)

• commented out print/write in Fortran subroutines, and add IMPLICIT NONE

cts 1.0-3

• changes from 1.0-1: pass a parameter TRACE in R function to Fortran (TRA), which controls printout. Also minorly improve R functions

cts 1.0-1 (2006-09-29)

• In Makevars, replace PKG_LIBS=$(LAPACK_LIBS) $(BLAS_LIBS) with PKG_LIBS=$(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS) Note on ‘cts’ VERSION 1.0-2 (2006-12-11)
• This version was used for some calculations with time deformation, not for package development purpose

cts 1.0 (2006-06-22)

• submitted the package to CRAN
