The target file is a txt file created by the user
where every input file (array, sample) is
attached to a experimental condition
Usage
readTargets(infile,verbose=FALSE)
Arguments
infile
name of the target file, for instance 'targets.micro.txt'
verbose
logical, if TRUE prints out output
Value
A 'data.frame' containing by the columns specified in the input file
targets.txt. This 'targets.txt' file must be created by the user.
Details
In the 'target' file (see Table 1 in vignette) we specify the
experimental conditions under which the data have been generated.
The target file MUST contain the following mandatory columns:
-FileName : Name of the array data file
-Treatment : Treatment effect
-GErep : Treatment effect in numeric code, from
'1' to 'n', being 'n' the number of the levels
of the treatment effect
Other explanatory variables specifying the experimental conditions might be
also included.
