[BioC] XCMS / mzR / Rcpp dependency issue

[Uwe Schmitt]

Hi,

I have some problems to install xcms for R 2.5.1 on Windows 7, 64 bit.
I follow the installation instructions and enter:

 > source("http://bioconductor.org/biocLite.R")
 > biocLite("xcms", dep=T)

this loads some packages and gives me a warning:
installed directory not writable, cannot update packages 'boot', 'class',
'KernSmooth', 'MASS', 'nnet', 'rpart', 'spatial'

If I want to check if xmcs is installed I get:

 > require("xcms")

Lade nötiges Paket: xcms
Lade nötiges Paket: mzR
Lade nötiges Paket: Rcpp
Error : .onLoad failed in loadNamespace() for 'mzR', details:
call: value[[3L]](cond)
error: failed to load module Ramp from package mzR
konnte Funktion "errorOccured" nicht finden
Failed with error: ‘Paket ‘mzR’ konnte nicht geladen werden’

I try to translate the messages to english:

load required packet: xcms
load required packet: mzR
load required packet: Rcpp
Error : .onLoad failed in loadNamespace() for 'mzR', details:
call: value[[3L]](cond)
error: failed to load module Ramp from package mzR
could not find function "errorOccured"
Failed with error: ‘Paket ‘mzR’ could not be loaded'

Any hints what is going wrong ? I installed xcms on an older machine six
months ago and I had no problems at all.

Kind Regards,

Uwe
