| multiEIC {Mosaic} | R Documentation |
Extract EICs from multiple files for multiple features.
multiEIC(rawdata = rawcoll, mz = data.frame(mzmin = pcame_mini$mzmin, mzmax = pcame_mini$mzmax), rt = data.frame(rtmin = pcame_mini$rt - 5, rtmax = pcame_mini$rt + 5), rnames = row.names(pcame_mini), byFile = F, XIC = F, getgauss = F, RTcorr = NULL)
rawdata |
a (named) list of xcmsRaw objects, e.g. generated by Mosaic::loadRawM, OR an MSnbase OnDiskMSnExp object |
mz |
a data.frame with minimum (column 1) and maximum (column 2) m/z values in each row. |
rt |
a data.frame with minimum (column 1) and maximum (column 2) retention time values (in seconds) in each row. |
rnames |
names of the rows in the result matrix, typically the row.names of the feature table, or the filenames if byFile =T. |
byFile |
a data.frame with columns File and Group , holding file paths and group names, respectively. |
XIC |
deprecated |
getgauss |
additionally, fit a gauss curve to each EIC (time consuming), defaults to FALSE |
RTcorr |
if not NULL, this RTcorr object will be used to adjust retention times. |
