DGObarplot: Draw a bar graph on the DO and GO analysis.

In JoelleJee/DGOplot: DO and GO Enrichment Analyses Plotting

Description

A function that draws a double bar graph of DO and GO analysis, ordered and colored by group and p.adjust value.

Usage

DGObarplot(
  DGOResult,
  showCategory = 8,
  DOcol = c("red", "darksalmon"),
  GOcol = c("blue", "lightskyblue"),
  pAdjustCutoff = 0.05
)

Arguments

DGOResult	DO and GO enrichment analysis result returned from enrichDGO().
showCategory	number of ontology groups to show from DO and GO each.
DOcol	color to use for plotting DO.
GOcol	color to use for plotting GO.
pAdjustCutoff	p.adjust cutoff value for ontology group to plot.

Value

Returns a double bar graph of DO and GO analysis.

• different color for DO and GO results

• color gradient by p.adjust value

• ordered by p.adjust value

Examples

## Not run: 
# load data from DOSE
library(DOSE)
data(geneList)
gene <- names(geneList)[abs(geneList) > 2]
result <- enrichDGO(gene, universe=names(geneList))

# tamper the data little bit to see 
# the full functionalities of DGOplot
result$DO@result$p.adjust <-  result$DO@result$p.adjust / 10
 
DGObarplot(result)
DGObarplot(result,
           DOcol = c("purple", "yellow"),
           GOcol = c("red", "blue"),
           showCategory = 6)

## End(Not run)
