Error with CDF and DB

[jsaintvanne]

During the runGC with CDF files and comparing with a DB, we obtain this error :

Error in x[, settings$timeComparison] : incorrect number of dimensions
Calls: runGC ... match.unannot.patterns -> sapply -> sapply -> lapply -> FUN -> mean

https://github.com/rwehrens/metaMS/blob/master/R/matchSamples2Samples.R#L173 It looks that due to a list of 1 element that is not a list but a matrix (probably because there is only one element in it)... So I should modify how the list has been made just here https://github.com/rwehrens/metaMS/blob/master/R/matchSamples2Samples.R#L31

After investigate a little, this parameter should be a list and in this case with cdf we obtain a matrix... For CDF :

So, after investigation, we obtain a matrix with this mapply function : https://github.com/rwehrens/metaMS/blob/master/R/matchSamples2Samples.R#L38

BUT apparently, we obtain a matrix only when ALL lists have the same length !

So, I should probably just add something to transform matrix into list like

as.list(as.data.frame(x))

This can be a problem when columns haven't the same length but we just said that we obtain a matrix ONLY when columns have the same length... !
