## Performs *set* membership on two Massvectors

### Description

Performs *set* membership on two Massvectors

### Arguments

`obx` | see below in Methods section
`oby` | see below in Methods section
`error` | measurement error in e.g. Da or as relative error in parts per million (ppm)
`ppm` | if `TRUE` then error in parts per million(ppm), in arbitrary units otherwise.
`uniq` | if `TRUE` compute non-crossing matching.

### Value

returns a vector of class `logical`

### Methods

obx = "numeric", oby = "numeric"
  :
obx = "Massvector", oby = "Massvector"
  :

### Examples

    data(pldata)
    pl1 <- pldata[[1]]
    pl2 <- pldata[[4]]
    fis.element(pl1[,1,drop=TRUE],pl2[,1,drop=TRUE],error=0.1,ppm=FALSE)
    fis.element(pl1,pl2,error=0.1,ppm=FALSE,uniq=FALSE)
