In tbgitoo/textureAnalyzerGels: Reading and analyzing texture analyzer data

analysis_list_to_dataframe

Description

Converts the output of foam_mechanical_analysis_list, which is a nested list (list of list), into a flat dataframe for use in plotting and statistical analysis.

Usage

analysis_list_to_dataframe(file_info,output_foam_mechanical_analysis_list)

Arguments

file_info	Description of the compression curves. This is a dataframe, which needs to contain as many lines as there are elements in data_list
output_foam_mechanical_analysis_list	Output by foam_mechanical_analysis_list. This is a list of lists

Value

A dataframe containing one line per estimated value. The values are described by the columns measurement, direction and point. The measurement indicates what is measured (stress, strain, distance, and so forth), the direction indicates whether this was obtained in the "down" or "up" cycle (compression or release), while the point column indicates the relevant segment on the foam compression curve (touchpoint, linear elastic segment, transition to plateau, plateau, transition to densification). As there are many measurements and points, as well as the "down" and "up" cycle, there are many lines in the return value for each line in file_info. The

Examples

data(CMC_concentration_data)
foam_mechanical_analysis_list_result=foam_mechanical_analysis_list(file_info=CMC_concentration_file_info, data_list=CMC_concentration_data,stress_column="pressure_reduced",stress_slope_column="pressureSlope_reduced")	

analyzed_data = analysis_list_to_dataframe(file_info=CMC_concentration_file_info,output_foam_mechanical_analysis_list=foam_mechanical_analysis_list_result)



# Usage of the dataframe: one has to select specific measurements at specific points and a specific direction

E_elastic_down = analyzed_data[analyzed_data$measurement=="E" & analyzed_data$point=="elastic" & analyzed_data$direction=="down",]

plot(value ~ CMC_conc, E_elastic_down[order(E_elastic_down$CMC_conc),],type="b",log="xy")
