News for Package vegperiod
Version 0.4.0
- introduced threshold
Tsum.crit for sum of day degrees
in function vegperiod()
- made plausibility check optional via new parameter
check.data (suggested by @rhabel)
- restructured documentation to provide more details on start and end
methods
- acknowledged funder in DESCRIPTION
- fixed a changed URL
Version 0.3.1
- if
StdMeteo does not find an end, it now reports the
last day of the year instead of 0.
Version 0.3
- fix
est.prev parameter used in start method Menzel. Now
averages as advertised (Thanks for catching this bug to @awellpott).
- switched to unit testing framework
tinytest
Version 0.2.7
- changed temperature plausibility checks because of severe winter
1956 with daily mean temperatures of -27 °C in Germany and even lower
and higher daily mean temperatures in climate scenarios.
Version 0.2.6
- fixed change of base URL of DWD open data (Thanks @ckluss for reporting and
pointing in the right direction)
- fixed download of recent monthly climate data. Breakage caused by
DWD file name schema change (#1). Thanks @rwoerde for reporting.
- corrected minimum R version. Argument
fileEncoding was
introduced to read.fwf() in R 3.2
Version 0.2.5
- replaced package ‘RCurl’ with ‘curl’ for downloading DWD Data
- stopped importing package ‘methods’
- fixed read.DWDstations() because DWD changed layout of station
list
- updated documentation of read.DWDdata() because DWD changed column
order of climate data files
Version 0.2.4
- vegperiod() checks if Tavg (daily mean temperature) is between -25
and 35 to catch temperatures multiplied by 10. Sometimes done to store
as integers. (thanks to Ronald Bialozyt for reporting a crash)
Version 0.2.3
- vegperiod() reports end of vegetation period always as integer
- new parameter ‘quiet’ to readDWDdata to suppress messages and
progessbar of download
- started unit testing with package ‘testthat’
Version 0.2.2
- start.method=‘Ribes uva-crispa’ using leaf out of gooseberry as
indicator. Developed by Germany’s National Meteorological Service
(DWD).
- est.prev can now be equal to number of provided years
- proper error message if only one year of data provided and previous
year’s chill days requested
Version 0.2.1
- cleaned up mangled output of start.method=‘StdMeteo’. StdMeteo now
behaves properly and returns a vector.
- use stats::filter() in the package to protected filter() against
getting run over by package dplyr (thanks to Cristabel Duran for
reporting).
Version 0.2.0
New Features
read.DWDdata() reads open meteo data from the Climate
Data Center (CDC) of Germany’s National Meteorological Service
(Deutscher Wetterdienst, DWD).read.DWDstations() fetches information about available
DWD stations
Major Changes
- renamed arguments in vegperiod() to clarify meaning / easier tab
completion:
- first.avg -> est.prev
- temp.sum -> Tsum.out
- method.start -> start.method
- method.end -> end.method
- renamed method
StdClimatolgy to StdMeteo /
ETCCDI in vegperiod() and brought calculations into
compliance with ETCCDI standard
Bug fixes and minor
improvements
- added a hack in method LWF-BROOK90 of vegperiod() to adjust for
different arithmetic precision in VBA version (thanks to Paul
Schmidt-Walter for providing climate.in files for comparision and help
finding the bug)
- fixed bug leading to crash of vegperiod() if argument
first.avg=0 (thanks to Ronald Bialozyt for reporting)
- the argument “dates” of vegperiod() accepts now also character
strings understood by
as.Date()
- rewrote help-page of vegperiod() and added references for all
methods
Version 0.1.0
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
