Create a generic microarray based input object
1 2 3 4 5 |
diff_genes |
A 2 two column data.frame where the first column are genes and the second column are p-values |
limma_probe_table |
A data.frame from |
annotated_exprs_matrix |
A matrix where the rows are genes and the columns samples. |
expression_matrix |
Normalized expression matrix where the samples are columns and probes are rows |
annotation_table |
A dataframe providing annotation for the probes. The dataframe should have 3 columns:
|
group1_indici |
vector containing indici for samples belonging to group 1 (Column numbers) |
group2_indici |
vector containing indici for samples belonging to group 2 (Column numbers) |
group1_label |
Label for each group 1, for example "patient" or "control" |
group2_label |
Label for each group 2, for example "patient" or "control" |
settings |
Settings used to generate the object. Used only internally by the package. |
This function allows the creation of a generic microarray based input object with the same class as objects created by
create_input_microarray
. This can be useful in the cases where you already have differentially
expressed genes, an annotated expression matrix or both and want to wrap that into an input object
to use in downstream analysis. All arguments are optional.
The function returns an object of class "MODifieR_input". The object is a named list containing the following components:
diff_genes |
A 2 two column data.frame where the first column are genes and the second column p-values |
limma_probe_table |
A data.frame from |
annotated_exprs_matrix |
A matrix where the rows are genes and the columns samples. Probes have been collapsed
into genes using |
expression_matrix |
A matrix, the original input expression matrix |
annotation_table |
A data.frame, the original annotation table used to annotate the probes |
group_indici |
A named list containing 2 numeric vectors. The names are the group labels and the values are the group indici |
