importM.COSMIC
Imports a tsv file containing CNA data from COSMIC. Imports a TSV file
mapping COSMIC gene IDs to HGNC gene symbols, required to match a CNA gene
symbol to an HGNC gene symbol (replaced by calls to fastMap()).
Returns an rCNA object in an RDS, where column names represents samples
(as TCGA-SampleID (note that the required information for a proper TCGA
mutation barcode is not available for COSMIC data, and that the sampleID
for this data is specific to COSMIC data)), row names are HGNC gene
symbols, and the values represent copy number.

|
fNameCNA |
The path to a TSV file with CNA data from COSMIC. |
outFName |
The path to an output file for the rCNA RDS object. |
silent |
Controls whether output to console should be suppressed. FALSE by default. |
writeLog |
Controls whether writing the result to the global logfile is enabled. TRUE by default. |
Return rCNA object of COSMIC CNA data as RDS compressed data frame file.
The format of the COSMIC CNA data is as follows. (through sftp, run get with this path: /files/grch38/cosmic/v80/CosmicCompleteCNA.tsv.gz)
