Description Usage Arguments Details Value Author(s) References Examples

This function estimated the common stress tolerance and susceptibility indices.

1	indices(data, x, y)

`data`	A data frame including genotype name (Gen), yp and ys
`x`	Response variable in non-stress condition (yp)
`y`	ys: Response variable in stress condition (ys)

This function is the main function of presented packages, using the mentioned formula calculated the indices and put the indices in a data frame (df1) to use in the other functions.
