[baj12]

Describe the bug
Error in cyto_plot after renaming samples:

Error in frameList[isFrame] : invalid subscript type 'list'

To Reproduce

library(CytoExploreR)


data(GvHD)
set <- GvHD[1:4]  
cyto_channels(set)
cyto_plot(set, 
          parent = "root",
          channels =  "FSC-H",
          density_stack = .5)
attributes(set)
ls(envir = attr(set,"frames"))
pd = attr(set,"phenoData")
attr(set, "subset")
sampleNames(set)
sampleNames(set) <- c("V1", "V2", "V3", "V4")
attributes(set)
ls(envir = attr(set,"frames"))


cyto_plot(set, 
          parent = "root",
          channels =  "FSC-H",
          density_stack = .5)

attr(set, "subset")
