Hi Everyone,

I am very new to R. When i run the code yesterday, it was working fine. I was able to find gene annotation.

somehow, today, when i try to run it again, it is giving me errors message that i don't understand. It says that it cannot open file. what file is it looking for?

##make sure to install and load annotationtool in R annotation_HGU133Plus2 <- read.csv("c://affymetrix.csv", colClasses =
"character")
annotation_probesets <- scan('c://ttest.csv',skip=1,what='')
dataDirectory <- system.file("data", package = "annotationTools")
annotation_stuff <- read.csv(paste(dataDirectory, 
annotation_HGU133Plus2, sep = "/"), colClasses = "character") myPS <- c(annotation_probesets)
getGENESYMBOL(myPS, annotation_stuff)
getGENEONTOLOGY(myPS, annotation_HGU133Plus2)
