I have a recent problem running the exprs() function on an AffyBatch object. Previously, I was able to run it, but all of a sudden, when I run, the following code snippet, I get a list instead of an object. And therefore, when I want to display it in Jupyter notebook, it gives me the following error:
AffyBatch object size of arrays=1164x1164 features (106 kb) cdf=HG-U133_Plus_2 (54675 affyids)
> expr = exprs(affy_obj)
ERROR while rich displaying an object: Error in FUN(X[[i]], ...): attempt to use zero-length variable name
However, if I use intensity() function, it works. Anyone knows what am I missing?
