Estimating the number of genes and pathways

[llrs]

While estimating it would be better to provide a parameter if we assume that the original object pass the check function or otherwise

[llrs]

• The function calc.nPathways estimates the number of pathways based on the number of genes.
• The function calc.nGenes estimates the number of genes based on the number of pathways.
• The function estimate.nGenes estimates the number of genes based on the genes per pathways.
• The function estimate.nPathaways estimates the number of pathways based on the pathways per gene.
  We need to introduce other estimates, we need a better naming scheme

[llrs]

Simplify, use one estimate function exported to the user and then use underlying functions depending on the information provided.
Still the functions should be named somehow, perhaps based on the information provided.
However this solution would mean that the output is inconsistent between different input parameters, sometimes a number, sometimes a vector.
It would mean any special print function?

Better provide a data.frame such like tidymodels (estimate, max, min) or something alike. If it cannot be calculated report NA
