ViDGER (Visualization of Differential Gene Expression using R), is an R
package that can rapidly generate information-rich visualizations for the interpretation of differential gene expression results from three widely-used tools: Cuffdiff
, DESeq2
, and edgeR
.
The stable version of this package is available on Bioconductor . You can install it by:
if (!require("BiocManager")) install.packages("BiocManager")
BiocManager::install("vidger")
If you want the latest version, install it directly from this GitHub repo:
if (!require("devtools")) install.packages("devtools")
devtools::install_github("btmonier/vidger", ref = "devel")
The stable release of vidger
has 9 visualization functions:
vsScatterPlot()
vsScatterMatrix()
vsBoxplot()
vsDEGMatrix()
vsVolcano()
vsVolcanoMatrix()
vsMAPlot()
vsMAMatrix()
vsFourWay()
To simulate the usage of the three aformentioned tools, "toy" data sets have been implemented in this package. Each of these data sets represents their respective R
class:
df.cuff
Acuffdiff
output file.df.deseq
ADESeq2
object class.df.edger
AnedgeR
object class.
To load these data sets, use the following command:
data("<object-type>")
...where "<object-type>"
is one of the previously mentioned data sets.
For additional information on these functions, please see the given documentation in the vidger
package by adding the ?
help operator before any of the given functions in this package or by using the help()
function.
