In PhilippJanitza/rootdetectR: Statistical analysis of rootdetection output with R

Calculate Summary Statistics for Normalized Rootdetection Data Set

Description

This function calculates sample size (n), median, mean, standard deviation (sd) and standard error (se) according to grouping variable/s (Factor1 and Factor2) and a dependent variable (LengthMM).

Usage

summary_stat(
  root_norm,
  col_grouping = c("Factor1", "Factor2"),
  col_value = "LengthMM"
)

Arguments

root_norm	data.frame; normalized Rootdetection data set
col_grouping	string or vector; name of the column/s that should be used as grouping variable/s (Label or c(Factor1, Factor2))
col_value	string; name of the column containing values (dependent variable) (LengthMM)

Value

data.frame; containing summary statistics for each Factor1 - Factor2 combination

Examples

# normalize Rootdetection Output
root_norm <- norm_10mm_standard(root_output)

# calculate summary statistic of standard Rootdetection data set
summary_stat(root_norm)

# calculate summary statistic grouped by Factor 1 only
summary_stat(root_norm, col_grouping = "Factor1", col_value = "LengthMM")
