vsBoxPlot {vidger} | R Documentation |
This function allows you to extract necessary results-based data from analytical objects to create a box plot comparing log10(FPKM or CPM) distributions for experimental treatments.
vsBoxPlot(data, d.factor = NULL, type = c("cuffdiff", "deseq", "edger"), title = TRUE, legend = TRUE, grid = TRUE)
data |
output generated from calling the main routines of either 'cuffdiff', 'DESeq2', or 'edgeR' analyses. For 'cuffdiff', this will be a '*_exp.diff' file. For 'DESeq2', this will be a generated object of class 'DESeqDataSet'. For 'edgeR', this will be a generated object of class 'DGEList'. |
d.factor |
a specified factor; for use with 'DESeq2' objects only. This input equates to the first parameter for the contrast argument when invoking the 'results()' function in 'DESeq2'. Defaults to 'NULL' |
type |
an analysis classifier to tell the function how to process the data. Must be either 'cuffdiff', 'deseq', or 'edger'. 'cuffdiff' must be used with 'cuffdiff' data; 'deseq' must be used for 'DESeq2' output; 'edgeR' must be used with 'edgeR' data. See the 'data' parameter for further details. |
title |
display the main title of plot. Logical; defaults to 'TRUE'. If set to 'FALSE', no title will display in plot. |
legend |
display legend of plot. Logical; defaults to 'TRUE'. If set to 'FALSE', no legend will display in plot. |
grid |
display major and minor axis lines. Logical; defaults to 'TRUE'. If set to 'FALSE', no axis lines will display in plot. |
