BatchQC Run BatchQC shiny app
batchqc_explained_variation Returns a list of explained variation by batch and condition combinations
batch_correct Batch Correct This function allows you to Add batch corrected count matrix to the SE object
batch_design This function allows you to make a batch design matrix
batch_indicator Batch and Condition indicator for signature data
bladder_data_upload Bladder data upload This function uploads the Bladder data set from the bladderbatch package. This dataset is from bladder cancer data with 22,283 different microarray gene expression data. It has 57 bladder samples with 3 metadata variables (batch, outcome and cancer). It contains 5 batches, 3 cancer types (cancer, biopsy, control), and 5 outcomes (Biopsy, mTCC, sTCC-CIS, sTCC+CIS, and Normal). Batch 1 contains only cancer, 2 has cancer and controls, 3 has only controls, 4 contains only biopsy, and 5 contains cancer and biopsy
check_valid_input Helper function to save variables as factors if not already factors
