Hi all,

During I working for DNA microarray data analysis using Bioconductor , I faced some problem about Quality Control  !!

When I have written this command qc() for example qc(dat) in R program , the result was : Error: could not find function "qc"  !!!!!! 

how I can solve this issue ?

Regards,

Tahani Hasan

Any time you see an error like that, it means that you haven't yet loaded the package that has that function. So you need to first load the package using library().

I also faced another problem with a mark "=" ,, like this command below:

 

> plotAffyRNAdeg(deg,col=cols)
> legend(legend=sampleNames(dat), x="topleft",
+ + lty=1, cex=0.5, col=cols)
Error: unexpected '=' in:
"legend(legend=sampleNames(dat), x="topleft",
+ lty="

what about it ??
