get.celfile.dates: Extract Dates from CEL files

In affyio: Tools for parsing Affymetrix data files

Usage

get.celfile.dates(filenames, ...)

Arguments

filenames	a vector of characters with the CEL filenames. May be fully pathed.

Details

The function uses read.celfile.header to read in the header of each file. The ScanDate component is then parsed to extract the date. Note that an assumption is made about the format. Namely, that dates are in the Y-m-d or m/d/y format.
