[R] Error in function (classes, fdef, mtable): unable to find an inherited method for function "indexProbes", for signature "exprSet", "character"

Hello Everyone,

I am writing programs in R from 7 months and I am able to solve most of the
errors/issues except for this current post. 

My Task is to read a Microsoft Excel file(textE_to_affy.csv) which contains
the Microarray Expression Values collected from the Illumina Microarray
experiment. These collected intensity values need to be normalized(Rank
Invariant Normalization) by using the R function
"normalize.AffyBatch.invariantset()". 

Since the normalize.AffyBatch.invariantset() method requires the input
argument to be an AffyBatch Object, I used the read.exprSet() method to
convert the intensity values present in the (textE_to_affy.csv) file into an
AffyBatch Object as follows: 
> testFile <- tempfile()
>textAffy<-read.table("textE_to_affy.csv",header=TRUE,sep=",",row.names=1)

I have observed that this same error message has been posted and answered in
a different context in this forum. Even though I am not using the S4 class
and method concepts here, I am getting this error. 

I have also uploaded the input file on which the normalization needed to be
performed.

Hence, I would be grateful for you if you can give some direction/advice for
me to overcome this error. 

Thanks a lot,

Pay attention to these messages. Use readExpressionSet instead!

This error should not occur with an ExpressionSet.

You are using a package that uses S4.
