hallo everybody,
I have a problem with qaProcess.marginevents() function from flowQ package
I'm following the example

>  library(flowQ)
>  data(GvHD)
>  dest<- tempdir()
>  qp<- qaProcess.marginevents(GvHD, channels=c("FSC-H", "SSC-H"),

that I got trying
>  ?qaProcess.marginevents

but the command
>  qp<- qaProcess.marginevents(GvHD, channels=c("FSC-H", "SSC-H"),

follows to the error message:
computing margin events...Error: no se pudo encontrar la función "boundaryFilter"
Error en filter(set, boundaryFilter(x, side = side)) :
   error in evaluating the argument 'filter' in selecting a method for function 'filter'

and I have no idea how to deal with this error.I will be very thankful if you could help me to solve this problem.

Best wishes,
Ewelina Bakala
