In pgomba/thermgRad: Tools to Visualize and Analyze Germination in Temperature Gradient Plates

Obtain T50, Germination Rate for each Petri dish in the thermal gradient

Description

This function transform an excel spreadshit cumulative germination data from every Petri dish into a grid containing petri dish label, T50 and Germination rate. See details to format the input data correctly. The last column must be the total number of viable seeds of each petri dish (germinated + fresh & mouldy after cut test). It does not have to be (necessarily) a 13 by 13 Petri dish grid

Usage

petri_grid(x)

Arguments

x	A data.frame, probably imported from an excel spreadsheet. See details for formatting

Details

Input for this function is a data frame with this format. Please note this table has a header and is relevant for the function for "Days" to be the header and not a row. This is because thermal plate germination data is probably recorded in a excel spreadsheet with this format
