One-way ANOVA Over Grouping Variable 2 Treatments

Description

The function performs a one-way ANOVA and Tukey post-hoc test over grouping variable 2 (Factor2). The function takes each control + treatment combination of grouping variable 2 and perfoms a one-way ANOVA iterating over grouping Variable 1 (Factor1). The p-values are adjusted using Benjamini-Hochberg correction.

Usage

onefacaov_fac2(
  root_norm,
  col_grouping1 = "Factor1",
  col_grouping2 = "Factor2",
  col_value = "LengthMM",
  control = "20",
  draw_out = F,
  file_base = "1fac_ANOVA_factor2",
  axis_label_size = 0.7,
  p_value_size = 0.8
)

Arguments

`root_norm`	data.frame; normalized Rootdetection data set
`col_grouping1`	string; name of the column that should be used as grouping variable 1 (Factor1)
`col_grouping2`	string; name of the column that should be used as grouping variable 2 (Factor2)
`col_value`	string; name of the column containing values (dependent variable) (LengthMM)
`control`	string; name of the grouping variable 2 (Factor2) control condition
`draw_out`	logical; If TRUE a matrix containing p-values is plotted in a pdf file
`file_base`	string; file base name of the pdf output (is needed if draw_out = TRUE)
`axis_label_size`	numeric; font size of axis labels in pdf file (if draw_out = TRUE)
`p_value_size`	numeric; font size of p-values in pdf file (if draw_out = TRUE)

Value

list; data.frames containing p-values for one-way ANOVA and Tukey post-hoc

Examples

# get data.frame containg p-values for one-way ANOVA and Tukey post-hoc over grouping variable 2
root_norm <- norm_10mm_standard(root_output)
onefacaov_fac2(root_norm, control = "20", draw_out = FALSE)

# plot p-value matrix as pdf output
onefacaov_fac2(root_norm, control = "20", draw_out = TRUE, file_base = "1fac_ANOVA_factor2")
# function creates a pdf file 1fac_ANOVA_factor2_28.pdf
