Dear Bioconductor: I am trying to read a *.csv file from a UBS microdrive using read.table. I am using R 2.0.1 on a G5 IMac. I tried the following: data <- read.table("DATASTOR:Data:dataset.csv",sep=",", header=T,na.string="NA") data <- read.table("DATASTOR::Data::dataset.csv",sep=",",header=T,na.string="N A") I have also tried variations on backward and forward backslashes, but none of the variations appear to work. I supect that the solution is rediculously simple, but I can't see it. Can someone help me? John
