run_viper() error

[ejfertig]

I'm trying to run the example provided for run_viper() in the documentation for this package but am getting the following error when using the code directly:

library(bcellViper)
data(bcellViper, package = "bcellViper")

acessing (human) dorothea regulons

for mouse regulons: data(dorothea_mm, package = "dorothea")

data(dorothea_hs, package = "dorothea")

run viper

tf_activities <- run_viper(dset, dorothea_hs,

•                        options =  list(method = "scale", minsize = 4,
  

•                                        eset.filter = FALSE, cores = 1,
  

•                                        verbose = FALSE))
  

Error in .check_expected_columns():
! Output columns are different than expected.
Expected: source, target, mor, likelihood
Extra:

Run rlang::last_trace() to see where the error occurred.

Thought welcome.
