plantphysioR

The goal of plantphysioR is to provide basic functions related to plant physiology, it contains functions related to various yield related indices, pigment content calculations and PEG6000 calculations

Installation

You can install the development version of plantphysioR from GitHub with:

# install.packages("devtools")
devtools::install_github("rameshram96/plantphysioR")

Example

library(plantphysioR)
#all_indices 
Ms<-mean(yield_data$Ys)
Ms<-mean(yield_data$Ys)
Yp<-yield_data$Yp
Ys<-yield_data$Ys
all_indices(Yp,Ys,Mp,Ms)
#This function calculates all the yield related indices inclued in the package
# calculation of Stress susceptibility index
ss_index(500, 350, 450, 370)
