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

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,
  spaces_first = TRUE
)

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.

spaces_first

logical. Whether blank lines should come before (TRUE, default) or after (FALSE) each line of sequence.

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,
    spaces_first = TRUE
)
#> [1] ""       "GGCGGC" ""       "GGC"   

convert_input_seq_to_sequence_list(
    "GGCGGCGGC",
    line_length = 3,
    spacing = 2,
    spaces_first = FALSE
)
#> [1] "GGC" ""    ""    "GGC" ""    ""    "GGC" ""    ""   

convert_input_seq_to_sequence_list(
    "GGCGGCGGC",
    line_length = 6,
    spacing = 0
)
#> [1] "GGCGGC" "GGC"
