From db9ae6a0c9cecb92048fde6f06af1da183c09b5f Mon Sep 17 00:00:00 2001 From: Johannes Ranke Date: Thu, 19 Nov 2020 15:41:24 +0100 Subject: Depend on parallel, doc improvements By depending on parallel instead of importing it, functions to set up and stop a cluster are always available when mkin is loaded. The use of multicore processing in mmkin on Windows is now documented in the help file, which brings mkin closer to a version 1.0 #9. --- docs/dev/reference/f_time_norm_focus.html | 283 ++++++++++++++++++++++++++++++ 1 file changed, 283 insertions(+) create mode 100644 docs/dev/reference/f_time_norm_focus.html (limited to 'docs/dev/reference/f_time_norm_focus.html') diff --git a/docs/dev/reference/f_time_norm_focus.html b/docs/dev/reference/f_time_norm_focus.html new file mode 100644 index 00000000..a95234a7 --- /dev/null +++ b/docs/dev/reference/f_time_norm_focus.html @@ -0,0 +1,283 @@ + + + + + + + + +Normalisation factors for aerobic soil degradation according to FOCUS guidance — f_time_norm_focus • mkin + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

object

An object containing information used for the calculations

...

Currently not used

moisture

Numeric vector of moisture contents in \% w/w

field_moisture

Numeric vector of moisture contents at field capacity +(pF2) in \% w/w

temperature

Numeric vector of temperatures in °C

Q10
