Error in normalize.quantiles(dataset0) : Matrix expected in normalize.quantiles

[Qpt-r]

Hi,
Thanks for developping this interesting tool.
It seems that the error:
Error in normalize.quantiles(dataset0) :
Matrix expected in normalize.quantiles

bulk_dataset <- bulk_dataset %>% mutate_all(as.numeric)
class(bulk_dataset)
[1] "data.frame"
infos1 <- Scissor_m(bulk_dataset, sc_dataset, phenotype, alpha = 0.05,

•               family = "cox", Save_file = 'Scissor_LIHC_survival.RData')
  

Error in normalize.quantiles(dataset0) :
Matrix expected in normalize.quantiles
此外: Warning message:
In asMethod(object) :
sparse->dense coercion: allocating vector of size 2.0 GiB
Called from: normalize.quantiles(dataset0)

Could you please give some help on ow to debug it ?
Many thanks.

maybe use "bulk_dataset <- as.matrix(bulk_dataset)" can solve the problem.
but the result is not good, all of the color is grey :(
