twofacaov: Two-Way ANOVA Over Grouping Variable 1 And 2

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

Two-Way ANOVA Over Grouping Variable 1 And 2

Description

The function performs a two way ANOVA and Tukey post-hoc test for normalized Rootdetection standard over grouping variable 1 and 2 (Factor1 and Factor2). Caution: In the actual version it is necessary to provide a Label column (grouping variable 1 and 2 separated by label delimiter (label_delim)) in addition to grouping variable 1 and 2 necessary.

Usage

twofacaov(
  root_norm,
  col_grouping1 = "Factor1",
  col_grouping2 = "Factor2",
  col_value = "LengthMM",
  col_label = "Label",
  label_delim = ";",
  summary_plots = F,
  draw_out = F,
  file = "2fac_ANOVA_all_vs_all.pdf",
  axis_label_size = 0.7,
  p_value_size = 0.8
)

Arguments

root_norm	data.frame; normalized Rootdetection data set
col_grouping1	string; column name of the first grouping variable (Factor1)
col_grouping2	string; column name of the second grouping variable (Factor2)
col_value	string; name of the column containing values (dependent variable) (LengthMM)
col_label	string; column name of label (combining grouping variable 1 and 2 separated by delimiter)
label_delim	character; defines how Factor1 and Factor2 are separated in Label
summary_plots	logical; If TRUE summary plots were printed (plot(aov))
draw_out	logical; If TRUE Matrix containing p-values is plotted in pdf file
file	string; file name of the pdf output (is needed if draw_out = T)
axis_label_size	numeric; font size of axis labels
p_value_size	numeric; font size of the p-values printed in pdf file

Value

list; data.frames containing p-values for one-way ANOVA and Tukey post-hoc over grouping variable 1 and 2 (Factor1 and Factor2)

Examples

# get data.frame containing p-values for two-way ANOVA and Tukey post-hoc

root_norm <- norm_10mm_standard(root_output)
twofacaov(root_norm, label_delim = ";", draw_out = FALSE)

# get data.frame and plot as pdf output

root_norm <- norm_10mm_standard(root_output)
twofacaov(root_norm, label_delim = ";", draw_out = TRUE, file = "2fac_ANOVA_all_vs_all.pdf")
#' # function creates a pdf file 2fac_ANOVA_all_vs_all.pdf
