Please write an algorithm in words not actual code to pull desired data from a matrix of data and get the desired 4 graph out out of legal crab per pot per district per year.

Legal crab is a recruit male, post recruit male and an adult female. Illegal crab are any pre recruit crab.

Example of the imported data matrix, row numbers correlate to the 14 lines of data on the king crab sheet.

King Crab Data Reading Material This is excerpts of the web sites README file. You will need to read this information to help you answer the questions This is a description of the Kodiak Island king crab survey data, distributed for the Data Analysis Exposition being sponsored by the Statistical Graphics and Statistical Computing Sections at the 1990 American Statistical Society Joint Statistical meetings in Anaheim. The main data set consists of king crab pot survey data for the years 1973 through 1986. The surveys were conducted in the waters around Kodiak Island, Alaska, using pots similar to the pots used by the commercial fishing fleet. (A crab pot is a trap that resembles a wooden crate.) A fixed sampling grid was used to place strings of pots (stations) consisting usually of 10 pots in open ocean, or of 2-5 pots in bays The pots were left in the water for periods of 16-24 hours, removed, and the crab counts recorded. The survey was conducted each summer, 2-4 weeks prior to start of the commercial fishing season. The crab counts are classified by size (roughly representing age) and sex into six categories. The basic survey data is a file "survey", containing a 3,450 by 14 matrix with these columns: 1. Year (last two digits) 2. Fishing district (one of four) 3. Station identifier (alphabetic) 4. The number of pots fished 5-6. Latitude and longitude of the location halfway between the first and last pot of the station 7. Number of pre-recruit-4 crab 8. Number of pre-recruit-3 crab 9. Number of pre-recruit-2 crab 10. Number of pre-recruit-1 crab 11. Number of recruit males 12. Number of post-recruit males 13. Number of juvenile females 14. Number of adult females
