Hi everyone, can anyone help me solve this problem with the ChAMP library (2.29.1), it tells me Anno not found in section 3 of Use Annotation Start

``` myImport<-champ.load(directory=getwd(),arraytype="EPICv2")

[ Section 3: Use Annotation Start ] ....

Error in rownames(Anno$ControlProbe) : object 'Anno' not found In addition: Warning messages: 1: In readLines(csvfile) : incomplete final line found on '/Users/aur/Desktop/Array/208160850024/Sample_Sheet_28_03_24.csv' 2: In data("AnnoEPICv2") : data set 'AnnoEPICv2' not found

You also need to install the matched ChAMPdata to use EPICv2. As the instruction here.

Run below code to install the ChAMPdata contains EPICv2 annotation.

git clone https://github.com/YuanTian1991/ChAMPdata.git
R CMD INSTALL ChAMPdata

Or by using devtools library function :

install_github("YuanTian1991/ChAMPdata")

(thank you for this great tool !)

You don't need to do either of the above suggestions.

library(BiocManager)
install("YuanTian1991/ChAMPdata")

will install without having to bother with how exactly it is being installed.

It is not clear that you can use ChAMP for the EPICv2 arrays. You might consider instead using minfi directly.
