merge two ramclustR objects
mergeRCobjects(
ramclustObj.1 = NULL,
ramclustObj.2 = NULL,
mztol = 0.02,
rttol = 30,
course.rt.adj = NULL,
mzwt = 2,
rtwt = 1,
intwt = 3
)
ramclustObj.1 |
ramclustR object 1: this object will be the base for the new object. That is all the features from ramclustObj.1 will be retained. |
ramclustObj.2 |
ramclustR object 2: this object will mapped and appended to racmlustObj1. That is only features which appear consistent with those from ramclustObj.1 will be retained. |
mztol |
numeric: absolute mass tolerance around mz |
rttol |
numeric: feature retention time tolerance. Value set by this option will be used during the initial anchor mapping phase. Two times the standard error of the rt loess correction will be used for the full mapping. |
course.rt.adj |
numeric: default = NULL. optional approximate retention time shift between ramclustObj.1 and ramclustObj.2. i.e if the retention time of ramclustObj.1 is on average 15 seconds longer than that of ramclustobj.2, enter '15'. if 1 is less than 2, enter a negative number. This is applied before mapping to enable a smaller 'rttol' value to be used. |
mzwt |
numeric: when mapping features, weighting value used for similarities between feature mass values (see rtwt, intwt) |
rtwt |
numeric: when mapping features, weighting value used for similarities between feature retention time values (see mzwt, intwt) |
intwt |
numeric: when mapping features, weighting value used for similarities between ranked signal intensity values (see rtwt, mzwt) |
Two ramclustR objects are merged with this function, mapping features between them. The first (ramclustObj.1) object use used as the template - all data in it is retained. ramclustObj.2 is mapped to ramclustObj.1 feature by feature - only mapped features are retained. A new ramlcustObj is returned, with a new SpecAbund dataset with the same column number as the ramclustObj.1$SpecAbund set.
returns a ramclustR object. All values from ramclustObj.1 are retained. SpecAbund dataset from ramclustObj.1 is moved to RC$SpecAbund.1, where RC is the new ramclustObj.
