I am trying to finish a microarray analysis. I need to select information from the A flavus package to find deferentially expressed genes. Select is not working in Annotation Dbi. How do I create a custom select function so that R recognizes the function? Thank you. cdf=AFLAVUSa520391F (22683 affyids) annotation=aflavusa520391f
library("aflavusa520391fcdf") anno<-select(aflavusa520391fcdf, + keys=(featureNames(eset)), + columns=c("SYMBOL","GENENAME"), + keytype="PROBEID") Error in select(aflavusa520391fcdf, keys = (featureNames(eset)), columns = c("SYMBOL", : could not find function "select"
