Hi all,
I have loaded the LIMMA and Biobase package and tried these commands:
library(limma)
library("Biobase")
data <- read.table("c:/temp/data.txt",header=T,row.names=1)
ExpressionData <- as.matrix(data[,c(2,3,4,6,7,8)])
eset <- new("ExpressionSet", exprs = ExpressionData)
design <- cbind(WT=1,P=c(0,1,1,0,1,1),G=c(0,1,0,0,1,0))
fit <- lmFit(eset,design)
But I keep getting an eroor message after "lmFit" that says:
Error in possibleExtends(cl, class2, class1Def, class2Def) :
trying to get slot "subclasses" from an object (class "classRepresentation")
that is not an S4 object
I am using R-2.9.2. Whats happening now? I have done exactly the same commands
in another computer and it works fine. I forgot which R version it was. But
after installing the latest version nothing works. Pls advice...
Regards,
Wendy
