I'm new to R. I've received data from a bead array, consisting of 24 samples.
I've installed the beadarray package from bioconductor.
The problem is that whenever I try to read the data into R it gives me an error message.
I don't know what I'm doing wrong (checked the directory)
The txt files look like this:
Loading required package: Biobase

Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :

What am I doing wrong?? Please help.
