Description Usage Arguments Value Examples

Description

find.clonotypes(.data, .targets, .method = c("exact", "hamm", "lev"),
  .col.name = "Read.count", .target.col = "CDR3.amino.acid.sequence",
  .verbose = T)

Arguments

.data

List with mitcr data.frames or a mitcr data.frame.

.targets

Target sequences or elements to search. Either character vector or a matrix / data frame (not a data table!) with two columns: first for sequences, second for V-segments.

.method

Method, which will be used to find clonotypes:

- "exact" performs exact matching of targets;

- "hamm" finds targets and close sequences using hamming distance <= 1;

- "lev" finds targets and close sequences using levenshtein distance <= 1.

.col.name

Character vector with column names which values should be returned.

.target.col

Character vector specifying name of columns in which function will search for a targets. Only first column's name will be used for matching by different method, others will match exactly. .targets should be a two-column character matrix or data frame with second column for V-segments.

.verbose

if T then print messages about the search process.

Value

Data.frame.
