1 year ago Not an expert, but did you see the data arrangement 3 from this tutorial? https://cran.r-project.org/web/packages/TropFishR/vignettes/lfqData.html - probably is what you want?

I am currently conducting research on shrimp stock assessment using the ‘TropFishR’ package to analyze a monthly carapace length frequency dataset. The package allows for the analysis of one year of data, specifically data collected from January to December of a particular year. Sample code for opening the library, working with an Excel file, and opening the dataset from the working directory is provided below:
Open the TropFishR library
library(TropFishR)
Open the Excel data file
library(openxlsx)
Set the working directory where the data is located
setwd
Open the dataset in the working directory
data <- read.xlsx("frequency.xlsx")
To reproduce the result
set.seed(1)
Define the date, assuming 15 as the midpoint of sampling days
1:12 indicates data collected from January to December
-2022 indicates the year, with the remaining codes remaining the same
dates <- as.Date(paste0("15-",01:12,"-2022"),format="%d-%m-%Y") However, if we have more than one year of data, how can we feed it into the ‘TropFishR’ package?
