gexmap: Main function of the GExMap package

Description Usage Arguments Author(s) References

View source: R/gexmap.R


GExMap analyze genomic distribution and GO of genes lists produced by transcriptomic studies.


gexmap(genome = "homosapiens", scale = "", source = "", res = "", isGO = FALSE, isMAP = TRUE, lim_chi = 5, global_test_choice = 4, pcorrd = 1, pcorrv = 1)



Annotation data and genomic localizations for all genes of a specific genome


The variable scale is the scale used to produce the graphics and to perform the statistical tests. Customizable in input in the gexmap(scale="") main function, the scale is set to 1 000 000 bp by default.


Folder which would contain alla data source as *.Rdata files.


Folder which will contain the results data files and folders.


TRUE/FALSE, customizable input variable to perform or no the Gene Ontology analysis of the tested gene list.


TRUE/FALSE, customizable input variable to perform or no the graphical reoprts of genomic analysis in pdf files.


Limit number of gene necessary to perform the CHI squared global test to statistically select the chromosomes. (used in the gestest() function).


Choice of chromosomes selection according to the results of the global statistical tests (see gextest() function).\ 1- At least CHI is OK\ 2- At least Wilcoxon is OK\ 3- CHI & Wilcoxon are OK\ 4- CHI OR Wilcoxon is OK\ Default value is set at 4.


Choice of pvalue correction method for the global tests (see gextest() function).


Choice of pvalue correction method for the local tests (see gextest() function).
