Plot CDR3 length distribution — plot_cdr3_length • tcrdistR

Draws a bar chart of CDR3 amino-acid sequence lengths for the alpha chain, beta chain, or both (faceted side-by-side).

Usage

plot_cdr3_length(
  tcr_df,
  chain = c("alpha", "beta", "both"),
  max_lengths = 30L,
  title = NULL
)

Arguments

tcr_df: Data.frame with cdr3a and/or cdr3b columns.
