Description Usage Arguments Value Errors
Loads an RNA exon expression data file as generated for the TCGA, returning its contents as a data frame. The input file has four tab-delimited columns, no header. The first column in the file describes the exon as <chr>:<start>-<end><strand>, the next three give count, coverage, and rpkm values.

path |
The path to the exon expression data file to load |
A data frame with the following columns from the exon expression file:
chr | The exon's chromosome |
start | The genomic start coordinate for the exon |
end | The genomic end coordinate for the exon |
strand | The strand the chromosome is on, one of + | - | * |
count | One of the exon expression level columns |
coverage | One of the exon expression level columns |
rpkm | One of the exon expression level columns |
The following fatal errors can occur:
No such file: path
The exon expression file named can not be found. Case, spelling permission and wrong working dir for relative paths are all common errors.
