ABSTRACT – The need to optimize seed quality assessment using new, more accessible, and modern computational resources

has led to the emergence of new tools. In this paper, we introduce SeedCalc, a new R software package developed to process

germination and seedling length data. The functions included in SeedCalc allow fast and efficient data processing, offering

greater reliability to the variables generated and facilitating statistical analysis itself since the data are already processed with

the appropriate structure to be statistically analyzed in the R software. SeedCalc is available free of charge at https://CRAN.Rproject.org/package=SeedCalc.

Index terms: R package, germination indexes, seedling uniformity, seed vigor, data analysis.
