Hello,
I wrote following R code to analyze
affymeterix
microarray
data
library(BiocGenerics) library(methods) library(Biobase) library(affy) library(limma) library(statmod) library(AnnotationDbi) library(DBI) targets <- readTargets ("affy_targets.txt") data <- ReadAffy(filenames=targets$FileName) eset <- rma(data) pData(eset)
But at this step while executing showed following error
Error in function (classes, fdef, mtable) :
Unable to find an inherited method for function ‘rma’ for signature ‘"AffyBatch"’
I am using this code from past 1 year with R 2.15.2 (now also
I
have
used
same version
)
which
worked perfectly all the time. But today it ran into
error
..
Just not able to resolve this :(
Can anybody please help
Thanks,
Nitin
