Since I did an R update including updating the minfi package to v1.14 (which I now deeply regret), an error keeps preventing me from reading my .idat files. I'm using the load.champ function which entails read.450k of the minfi package. The file path he's trying to read is wrong and reads like "c:/myDir/c:/myDir/..."

Probably, it's a simple bug which was also mentioned and fixed here. I didn't have it in minfi v1.12 so it probably has returned.

Thanks in advance for any help,
