plot_by_component: Plot by Treatment component

In brentpm2/FIELD_PRO_ANALYSIS: FieldPro Output Data Management and Analysis

Description

Constructs a bar chart of a provided response variable for all treatments containing a specified component within a trial. Exports graph to pdf only. Exports data used to generate graph to tab separated file.

Usage

plot_by_component(datafile, 
                  treatment_list, 
                  component, 
                  trial = "", 
                  resp_var = "DATA")

Arguments

datafile	A dataframe containing the column specified as resp_var and 'SUMMARY TRT#', and 'TRIAL #'. This dataframe is contained within the output of the 'readallsheets' function.
treatment_list	A dataframe containing the columns 'TREATMENT COMPONENT', one of which corresponding to component, and 'SUMMARY TRT #'. This dataframe is contained within the output of 'readallsheets' function.
component	A character string corresponding to at least one entry within the treatment_list column 'TREATMENT COMPONENT'.
trial	A character string corresponding to an entry within the 'TRIAL #' column of dataframe. Optional, as not specifying a value will result in the first trial being used.
resp_var	A character string corresponding to the column header present within dataframe, which contains numeric data.

Value

returns an aggregated datafile subsetted to treatments which contain the specified component, aggregating multiple instances of a given treatment.

                                              "c","b"))

                       "TRIAL #" = c(1,1,1,1,1,1,2))
names(datafile) <- c("DATA","SUMMARY TRT#","TRIAL #")
plot_by_component(datafile = datafile,
                  treatment_list = trtlist,
                  component = "a",
                  resp_var = "DATA")
