plotEnrichment: Plot and match singular enrichment results

In PEIMAN2: Post-Translational Modification Enrichment, Integration, and Matching Analysis

Plot and match singular enrichment results

Description

This function can be used to plot results of singular enrichment analysis for one set of protein. It can also be used to integrate and match the results of two separate singular enrichment analysis and plot the common PTMs. For more details please see examples.

Usage

plotEnrichment(x, y = NULL, sig.level = 0.05, number.rep = NULL, plotit = TRUE)

Arguments

x	A data frame that contains singular enrichment results generated by runEnrichment
y	Default value is NULL. If provided by a singular enrichment results, the matching results of x and y are plotted.
sig.level	The significance level to select post-translational modification (based on their corrected p-value). Note that sig.level applies to both x and y simultaneously.
number.rep	Only plot PTM terms that occurred more than a specific number of times in UniProt database. This number is set by number.rep parameter. The default value is NULL.
plotit	a logical indicating whether you want to draw the plot (TRUE, default value) or you want to return the plot (FALSE).

Value

Plot.

Examples

## Enrichment analysis for the first protein list
enrich1 <- runEnrichment(protein = exmplData1$pl1, os.name = 'Homo sapiens (Human)')
## Plot results for first protein list
plotEnrichment(x = enrich1)

## Enrichment analysis for the second protein list
enrich2 <- runEnrichment(protein = exmplData1$pl2, os.name = 'Homo sapiens (Human)')
## Plot results for second protein list
plotEnrichment(x = enrich2)

## Integrate and match the results of two separate singular enrichment analysis
plotEnrichment(x = enrich1, y = enrich2)
plotEnrichment(x = enrich1, y = enrich2, number.rep = 5)
