Hi, I'm new to microarray analysis and aroma.affymetrix I'm trying to create a dynamic report, output using arrayexplorer but i'm getting this error:
Warning messages: 1: In is.na(x) : is.na() applied to non-(list or vector) of type 'NULL' 2: In writeImages.SpatialReporter(reporter, arrays = arrays, aliases = aliases, : No color maps specified. Nothing to do. 3: In is.na(x) : is.na() applied to non-(list or vector) of type 'NULL' I'm trying to analyze huex chips. This is a summary of my code thus far if it's of any help: cdf<-AffymetrixCdfFile$byChipType("HuEx-1_0-st-v2") cs<-AffymetrixCelSet$byName("Control", chipType="HuEx-1_0-st-v2") qn<- QuantileNormalization(cs) csN <- process(qn) plm<- RmaPlm(csN) fit(plm) ces<- getChipEffectSet(plm) rs<-calculateResidualSet(plm) ae<-ArrayExplorer(rs) process(ae) ###this is where i see the error Any suggestions would be greatly appreciated!!
