convert_input_seq_to_sequence_list: Split a single input sequence into a vector of "lines" for...

In ggDNAvis: 'ggplot2'-Based Tools for Visualising DNA Sequences and Modifications

Split a single input sequence into a vector of "lines" for visualisation (visualise_single_sequence() helper)

Description

Takes a single input sequence and an integer line length, and splits the input sequence into lines of that length (with the last line potentially being shorter).

Optionally inserts empty strings "" after each line to space them out.

Usage

convert_input_seq_to_sequence_list(
  input_seq,
  line_length,
  spacing = 1,
  start_spaces = FALSE,
  end_spaces = FALSE
)

Arguments

input_seq	character. A DNA/RNA sequence (or for the purposes of this function, any string, though only DNA/RNA will work with later functions) to be split up.
line_length	integer. How long each line (split-up section) should be.
spacing	integer. How many blank lines to leave before/after each line of sequence. Defaults to 0.
start_spaces	logical. Whether blank lines should also be present before the first line of sequence. Defaults to FALSE.
end_spaces	logical. Whether blank lines should also be present after the last line of sequence. Defaults to FALSE.

Value

⁠character vector⁠. The input sequence split into multiple lines, with specified spacing in between.

Examples

convert_input_seq_to_sequence_list(
    "GGCGGCGGC",
    line_length = 6,
    spacing = 1,
    start_spaces = TRUE,
    end_spaces = TRUE
)

convert_input_seq_to_sequence_list(
    "GGCGGCGGC",
    line_length = 3,
    spacing = 2
)

convert_input_seq_to_sequence_list(
    "GGCGGCGGC",
    line_length = 3,
    spacing = 2,
    end_spaces = TRUE
)

convert_input_seq_to_sequence_list(
    "GGCGGCGGC",
    line_length = 6,
    spacing = 0,
    start_spaces = TRUE,
    end_spaces = FALSE
)
