Comparison Class
Comparison Class
Details
An R6 class that represents a comparison between two groups of samples. This class contains the comparison name, the group order, and the comparison table. It includes methods to initialise, print, and validate the data.
Public fields
comparison_name
Character. The name of the comparison.
group_order
Character vector. The order of groups for the comparison, with length 2. The first element is treated as the "control" group, and the second as the "test" group.
comparison_table
A data.table that contains the group, sample, and condition information for the comparison.
Methods
Method new()
Create a new Comparison object.
Usage
Comparison$new(comparison_name, group_order, comparison_table)
Arguments
comparison_name
A character string representing the name of the comparison. Must be of length 1 and not exceed 100 characters.
group_order
A character vector specifying the order of groups for the comparison. Must be of length 2.
comparison_table
A data.table that contains group and sample information for the comparison. It should have two columns, named "group" and "sample". The "group" column identifies the clinical group to which each sample belongs, and the "sample" column lists the names/IDs of the samples. The groups in this table should match the names specified in `group_order`. Print a summary of the Comparison object.
Method print()
Examples
comparison <- Comparison$new(
comparison_name = "Treatment vs Control",
group_order = c("Control", "Treatment"),
comparison_table = data.table::data.table(
group = c("Control", "Control", "Treatment", "Treatment"),
sample = c("Sample1", "Sample2", "Sample3", "Sample4")
)
)
#> Treatment vs Control: deriving condition "control", "test" from group_order argument: control - Control, test - Treatment
print(comparison)
