I have downloaded data from EMBL-EBI (ArrayExpression myocardial infarction) Acession number E-MTAB-3573 raw data, cel file name (Wangyaping normal and disease condition, organism HOMO Sapiens). I have used this paper (Microarray Data Analysis for Transcriptome Profiling) command line RUN in Rstudio, Some result has come out such as Data Preprocession, Normalisation Gene Expression, Gene Annotation, quality Assessement, after that Genefilter command line has to RUN the result come out Error in ncol(eset) 'eset.filt' not found. I have atteched this paper PDF. Please sort out this problem. Thanks Dear
If you get an error from R saying
Error in ncol(eset) 'eset.filt' not found.
You can interpret that as R saying that this thing you are calling 'eset.filt' doesn't exist. And the reason it doesn't exist is most likely because you never made it (or you tried to, but R gave you another error at that step, saying it couldn't make it).
