I have a set of gpr files that I have read in using read.maimages(),
all of them ending with the number and the date of the experiment.
When I plot the intensities using boxplot() I get the full name of the
sample, i.e. with these long endings. How can I remove these endings?
slide 27_3_210408 slide 27_3_210408.gpr
slide 28_3_210408 slide 28_3_210408.gpr
slide 31_3_210408 slide 31_3_210408.gpr
slide 32_3_220408 slide 32_3_220408.gpr
slide 33_3_220408 slide 33_3_220408.gpr
After looking in the archives of BioC and R I tried the following code
and variations of that but with no luck (I am probably far off the
right expression). I am trying to store the filenames under a vector
that can be given as argument to boxplot
> names = sub('(_3_)(\.)','',data$targets,perl=TRUE)
Can anyone help me?
