Fish#

Data set for modeling weight on the other variables. Data was first presented in a publication from 1917.

Apparently, observation 143 had 6 roach in its stomach and may be an outlier.

Initialization#

library(fosdata)
data <- fosdata::fish

Accessing fields#

data <- fosdata::fish
width_percent <- data$width_percent # Just a random field in the dataset

Interactive R Sample#

You can use the R editor below to interactively explore the dataset and generate plots. This contains a fully self-contained R environment with fosdata, ggplot2, and dplyr loaded.

LLM instructions#


If using an LLM, you can copy-paste the following instructions to accompany your prompt to inform the model of the fields and their types in the dataset.
