Error: could not find function "xcmsSet"

[Lucas Schwartzenberg]

When I try to use "c) Run XCMS to pick peaks and convert to peakML files"

I keep getting this error:

Error: could not find function "xcmsSet"

I can get around the error by

library (xcms)

And then manually reentering the commands from the file, but this is not long term solution for me.
Is there some way for the xcms-library to be loaded automatically?
