run_estimation: A function to perform a statistical test at a sgRNA-level, deprecated.

Description

A function to perform a statistical test at a sgRNA-level, deprecated.

Usage

run_estimation(
  sgcount,
  design,
  group_a,
  group_b,
  delim = "_",
  ge_id = NULL,
  sg_id = NULL
)

Arguments

sgcount

This data frame contains read counts of sgRNAs for the samples.

design

This table contains study design. It has to contain `group.`

group_a

The first group to be tested.

group_b

The second group to be tested.

delim

The delimiter between a gene name and a sgRNA ID. It will be used if only rownames contains sgRNA ID.

ge_id

The column name of the gene column.

sg_id

The column/columns of sgRNA identifiers.

Value

A table contains the sgRNA-level test result, and the table contains these columns:

  • `sgRNA': The sgRNA identifier.

  • `gene': The gene is the target of the sgRNA

  • `n_a': The number of replicates of the first group.

  • `n_b': The number of replicates of the second group.

  • `phat_a': The proportion value of the sgRNA for the first group.

  • `phat_b': The proportion value of the sgRNA for the second group.

  • `vhat_a': The variance of the sgRNA for the first group.

  • `vhat_b': The variance of the sgRNA for the second group.

  • `cpm_a': The mean CPM of the sgRNA within the first group.

  • `cpm_b': The mean CPM of the sgRNA within the second group.

  • `logFC': The log fold change of sgRNA between two groups.

  • `t_value': The value for the t-statistics.

  • `df': The value of the degree of freedom, and will be used to calculate the p-value of the sgRNA.

  • `p_ts': The p-value indicates a difference between the two groups.

  • `p_pa': The p-value indicates enrichment of the first group.

  • `p_pb': The p-value indicates enrichment of the second group.

  • `fdr_ts': The adjusted P-value of `p_ts'.

  • `fdr_pa': The adjusted P-value of `p_pa'.

  • `fdr_pb': The adjusted P-value of `p_pb'.
