This was reported a while ago by Dan Tenenbaum, forgotten about by me and
fixed tonight in minfi v1.13.2
The previous use of the read.450k.exp function, where there was both a
base = SOMETHING
and a targets object (created by read.450k.sheet) with a targets$Basename
with values like
is no longer support (it used to be that the base argument was ignored).
User now just have to do
sheet = read.450k.sheet(ARGS)
rgset = read.450k.exp(targets = sheet)
We now support giving a base argument in case targets$Basename does not
contain the full path.
And this time I hope it works....
