Obtain the mean length (cm) at age for each year and season. This function is
used within get_data so is generally not needed directly. It simply
structures the input data.frame into an array.
Value
A numeric array with dimensions \[year, season, age\] containing mean length (cm) at age for each year and season.
Details
The input data.frame must contain the mean length (cm) at age arranged
into the columns Year, Season, and ages 0 to 30:
| Year | Season | 0 | 1 | ... | 29 | 30 |
| 1931 | 1 | 45 | 57.1 | ... | 74.1 | 88.8 |

| 2022 | 2 | 50 | 68.9 | ... | 184.0 | 184.0 |
Examples
length_mu_ysa <- get_length_at_age(length_mean = sbt::length_mean)
