Normalise open-ended DRAGEN FASTQC position/length bin tokens

DRAGEN FASTQC fastqc_metrics.csv position and read-length tokens are usually a single integer (150) or a closed range (145-152), but with a coarser --fastqc-granularity (or reads longer than the top bin) DRAGEN also emits open-ended terminal bins: 256+ (positions) and >=255 (read lengths). This strips the open-bin markers (+, >=, >, =) so the token collapses to its single integer bound. Closed ranges (A-B) are left untouched for a subsequent separate_longer_delim("-") to expand.

Without this, as.integer("256+") / as.integer(">=255") would silently coerce to NA and drop the top position/length bin.

Usage

fastqc_bin_open(v)

Arguments

v

(character())
Vector of raw position/length bin tokens (with any trailing bp already removed).

Value

(character()) Tokens with open-bin markers stripped.

Examples

fastqc_bin_open(c("150", "145-152", "256+", ">=255"))
#> [1] "150"     "145-152" "256"     "255"
