Hi Elisabeth,

I am having a similar problem to the one which you posted to the following
link:
https://stat.ethz.ch/pipermail/bioconductor/2013-February/050949.html

did you ever find the solution, I am receiving the same error:
In FUN(newX[, i], ...) : NAs introduced by coercion

Any help would be much appreciated,

Yours,
