Unexpected symbol with code

General
#1

Hi, I am trying to put this code into R, but it keeps telling me I have an "unexpected symbol."

phenoData<-read.csv("pheno.txt",header=TRUE,sep="\t")design<-model.matrix(~diagnosis,phenoData)fit<-lmFit(eset,design)

Error: unexpected symbol in "phenoData<-read.csv("pheno.txt",header=TRUE,sep="\t")design"

#2

Try it this way

phenoData <- read.csv("pheno.txt", header=TRUE, sep="\t")

design <- model.matrix(~diagnosis, phenoData)

fit <- lmFit(eset, design)

Hello,

Yes I tried it this way as well but got the following error.

design <- model.matrix(~diagnosis, phenoData)
Error in eval(predvars, data, env) : object 'diagnosis' not found

#5

Thank you for the help!

I realized I specified the data in the txt file as something other than "diagnosis", which is why it was unrecognizable.
