plot_design(
    go_id, result, eSet,
    factors=colnames(pData(eSet)), main="", main.Lsplit=NULL, ...)

Arguments

go_id

A Gene Ontology (GO) identifier represented by at least one gene in the dataset.

result

The output of GO_analyse() or a subset of it obtained from subset_scores().

eSet

ExpressionSet of the Biobase package including a gene-by-sample expression matrix in the AssayData slot, and a phenotypic information data-frame in the phenodata slot. In the expression matrix, row names are Ensembl gene identifiers or probeset identifiers, and column names are sample identifiers. In the phentypic data-frame, row names are sample idenfifiers, column names are grouping factors and phenotypic traits usable for the one-way ANOVA.

factors

A set of column names from phenodata. Each of these values will be represented on the X-axis to investigate its effect on the average expression of a given genes for each level of that factor.

main

Changes the main title of the plots.

main.Lsplit

Number of characters after which a new-line character will be inserted in the main title. If this would occur within a word, the new-line character will be inserted before this word. Default is NULL, leaving the title on a single line.

...

Additional arguments which will be passed on to the plot.design() function.

Value

The output of the plot.design() function.
