Reference Values Data Frame

Source: R/sample_data.R
ref_df.Rd

A data frame containing population-level reference values for methylation probes, used for imputing completely missing probes when target data lacks specific CpG sites. Values derived from large-scale population methylation studies.

Usage

ref_df

Format

A data frame with 20 rows (CpG probes) and 2 columns:

mean

Population mean beta values for each probe

median

Population median beta values for each probe

Primary applications:

  • Filling completely missing probes with reference_fill

  • Providing population baselines for comparison

  • Supporting quality control and outlier detection

str(ref_df)
#> 'data.frame':	20 obs. of  2 variables:
#>  $ mean  : num  0.399 0.662 0.495 0.528 0.677 ...
#>  $ median: num  0.369 0.788 0.528 0.435 0.782 ...
