Dear list,

Is there any specific requirement for installation of affycoretools? like the version of R, etc. I am trying to install affycoretools, but there is always some error msg like:

Error: package 'GO.db' required by 'GOstats' could not be found.
After I fix the above error, there is some new error:

Error: package 'DBI' required by 'AnnotationDbi' could not be found
I fix this one there is some new one and seems that it will never end. 

So what should I do in order to install affycoretools? 
In addition, the function affystart in affycoretools can be used to plot the distribution of intensity, what is the corresponding function in package affy to perform the same task? I am trying to plot the intensity distribution from two batches of data. 

Thanks a lot! Happy holidays,

James
