Greetings!!

To see the contents of .cel file in R/Bioconductor i used the following commands

celpath="R/win-library/3.3"
> data=ReadAffy(celfile.path = celpath)
> data
                  AffyBatch object
                  size of arrays=1164x1164 features (10 kb)
                  cdf=HG-U133_Plus_2 (??? affyids)
                  number of samples=1
       Error in getCdfInfo(object) : 
                  Could not obtain CDF environment, problems encountered:
                  Specified environment does not contain HG-U133_Plus_2
                   Library - package hgu133plus2cdf not installed
                    Bioconductor - could not connect
> expr = exprs(data)
> int = intensity(data)
> expr[1:10,]
    1     2     3     4     5     6     7     8     9    10 
  110 12382   134 12731    66    90 12682   105 12725   137 
> int[1:10,]
    1     2     3     4     5     6     7     8     9    10 
  110 12382   134 12731    66    90 12682   105 12725   137 

what does the answer from command exprs and intensity indicate.. is it possible to view the whole file.

thanking in advace.

Both exprs and intensity do the same thing (note you got identical results!). They extract the matrix of expression values, which is in some sense 'the contents of a .cel file'.

It is possible to view the whole file, but you will have to define what you mean by 'view'. Simply typing expr at the R prompt will cause R to print the first 10,000 of the values, which in some sense is 'viewing' the data. You could also make a boxplot or a density plot, which to me at least is a more reasonable way to 'view' about 1.3 million numbers.

But rather than asking how to do something trivial, could you say exactly what you are trying to do? I can't imagine it's useful to look at a million different numbers, so I imagine there is a larger goal in mind.

i actually want to understand the contents of .CEL file
