view_terms()

# Get an authentication token for use with the ScPCA Portal
auth_token <- get_auth(email = "your.email@example.com", agree = TRUE)

# Get the sample metadata for a project
sample_metadata <- get_sample_metadata(project_id = "SCPCP000001")

# Download a data for a sample
# this function returns a vector of the downloaded file paths
file_paths <- download_sample(
  sample_id = "SCPCS000001",
  auth_token = auth_token,
  destination = "scpca_data",
  format = "sce"
)
